Description

Technical Field

[0001] This invention relates to the field of flight training technology, and in particular to a simulation device and method for flight training. Background Technology

[0002] Flight simulation training devices are training equipment used to practice flight operation skills under various conditions. They can simulate the static and dynamic characteristics of flight equipment, as well as various visual conditions and physical factors such as sound, overload, and vibration. By using flight simulation training devices, pilots can master new technologies and equipment more quickly, improve the efficiency of equipment use, and save training costs. Some flight simulation training devices can also simulate the impact of weather on pilots.

[0003] A Chinese invention patent with publication number CN118116261A discloses a flight simulation training device. This device uses a simulation screen mechanism in conjunction with a flight display screen to simulate the impact of rain on flight, providing trainees with training in rainy weather. The technical solution employed involves water dripping from above and splashing onto the glass of the simulation screen mechanism to simulate the pilot's obstructed vision in rainy weather. However, this simulation method has certain drawbacks. At high altitudes, the aircraft travels at high speed relative to the surrounding airflow, experiencing significant wind resistance. When the airflow passes over the aircraft's window surface, it blows away water droplets before they can flow downwards, creating a continuous, horizontally flowing water trail. This flow pattern of water droplets has a completely different impact on the pilot's vision obstruction compared to a downward dripping pattern.

[0004] Therefore, in view of the fact that the simulated state of raindrops falling on the aircraft window in the existing rain flight simulation device is different from the actual high-altitude flight situation and has low realism, a rain flight simulation device with a blowing structure can be designed to simulate the effect of the surrounding airflow blowing water droplets on the window during high-altitude flight, and to simulate the state of obstructed vision during rainy flight with higher realism. Summary of the Invention

[0005] To overcome the problem that the simulated raindrops falling on the aircraft window in existing rain flight simulators differ from the actual high-altitude flight conditions.

[0006] The technical solution of this invention is as follows: a simulation device for flight training, comprising a console, a control cabinet mounted on one side of the console, a simulator mounted on the control cabinet, and a display screen. The display screen is used to display simulated flight images. It also includes a seat mounted on the console, a water supply assembly mounted inside the control cabinet, and a lift control assembly and a speed control assembly mounted on the console. The water supply assembly is used to supply water to the simulator, which is used to simulate the impact of rainy weather on flight visibility. Both the lift control assembly and the speed control assembly are signal-connected to the control unit of the display screen. The lift control assembly controls the display screen to simulate flight ascent or descent, and the speed control assembly controls the display screen to simulate flight acceleration or deceleration. The console is used to collect data from the lift control assembly and the... The speed control component outputs a signal and sends it to the water supply component. The simulator includes two parallel glass plates, several drainage holes at the top of the simulator, and a drainage trough at the bottom of the simulator. The two glass plates form a simulation chamber. A water circulation component is installed inside the control cabinet, and a water pumping component and a blower component are installed inside the simulator. The water circulation component is used to input water from the simulator into the water supply component, and the water pumping component is used to spray water from the simulator. The speed control component is signal-connected to the water pumping component. The blower component is used to deliver gas into the simulator. When the simulated flight speeds up, the water pumping component increases the water spraying speed, and the blower component increases the gas delivery speed. When the simulated flight speeds down, the water pumping component decreases the water spraying speed, and the blower component decreases the gas delivery speed.

[0007] Preferably, the water supply assembly includes a water supply tank and a water pump installed in the control cabinet. The water pump inlet is connected to the water supply tank, and the water pump outlet is connected to the simulator via a pump pipe.

The water tank is located below the drain trough, and the cover plate is installed on the upper end of the water supply chamber. When the first electric valve is opened, water in the water tank flows into the water supply chamber along the seepage pipe, the first electric valve, and the drain pipe. When the first electric valve is closed, the water level in the water tank continues to rise.

[0010] Preferably, the water circulation assembly is equipped with an audio-visual simulation component to simulate lightning and thunder during rain. This component includes a guide rod fixedly connected to the lower end of the water tank, a return spring mounted on the guide rod, a tension sensor mounted on a balance platform, a flashlight mounted in the simulator, and a sound generator mounted on the balance platform. The guide rod is slidably connected to the balance platform, allowing the water tank to move up and down axially along the guide rod. One end of the return spring is connected to the guide rod, and the other end is connected to the tension sensor, which detects the tension of the return spring. The flashlight simulates lightning, and the sound generator simulates thunder. A first contact switch is installed at the bottom of the water tank, and another first contact switch is installed at the top of the balance platform. As the water tank moves downwards, the tension sensor sends a signal to the control unit of the flashlight. When the water tank moves downwards until both first contact switches are energized, the sound generator emits thunder.

[0011] Preferably, the water-lifting assembly includes an upper roller movably connected to the top of the simulation chamber, a lower roller movably connected to the bottom of the simulation chamber, two first rubber wheels respectively connected to the upper roller and the lower roller, a first belt connecting the two first rubber wheels, and a motor mounted on the simulator. The first rubber wheels on the upper roller are fixedly connected to the output end of the motor. The upper roller is positioned below the drain hole, and the lower roller is positioned above the drain trough. The motor is used to drive the upper roller to rotate, and the first rubber wheels and the first belt are used to transmit the power of the upper roller to the lower roller. The upper roller is used to spray the water dripping from the drain hole, and the lower roller is used to spray the water in the drain trough.

[0012] Preferably, the blowing assembly includes a wind chamber located on one side of the simulator, several fans located inside the wind chamber, second rubber wheels fixedly connected to each fan, second belts drivingly connected to each second rubber wheel, a drive gear fixedly connected to the upper roller, a driven gear fixedly connected to one of the second rubber wheels, and an air outlet located on one side of the wind chamber.

The transmission shaft is used to transmit the power of the lower roller shaft to the transmission disc, and the transmission disc is used to drive the rocker arm to push the push rod and the push plate to move up and down reciprocally.

[0014] Preferably, the control cabinet is equipped with an air supply assembly, which includes an airbag housing installed inside the control cabinet, a partition fixedly connected to the airbag housing, a second electric valve installed at the bottom air inlet of the airbag housing, and an exhaust pipe fixedly connected to the airbag housing at one end. A push plate is fixedly connected above the airbag housing. The second electric valve is used to open or close the bottom air inlet of the airbag housing, and the other end of the exhaust pipe is connected to the water supply tank. The exhaust pipe is used to input the gas inside the airbag housing into the water supply tank. A second contact switch is installed at a corresponding position on the push plate and on the control cabinet. A third contact switch is installed on both the push plate and the partition. The push plate moves down until the third contact switch is installed. When the contact switch is energized, the second electric valve opens the air inlet; when the push plate moves up until the second contact switch is energized, the second electric valve closes the air inlet; a filter assembly is installed on the water circulation assembly. The filter assembly includes a connecting pipe fixedly connected to the cover plate at one end, a filter cartridge installed at the lower end of the balance platform, and an air inlet pipe connected to the filter cartridge at one end. The other end of the connecting pipe is connected to the filter cartridge, and the other end of the air inlet pipe is connected to the air chamber of the blower assembly. The connecting pipe is used to input the gas in the water supply chamber into the filter cartridge, and the air inlet pipe is used to input the air in the filter cartridge into the blower assembly. An activated carbon layer is provided inside the filter cartridge, which is used to filter the gas entering the filter cartridge.

[0015] A method for flight training, employing a flight training simulation device as described above, includes the following steps: S1: The trainee first sits in the seat and places his hands on the first push handle of the lift control component and the second push handle of the speed control component. The simulator is activated, and the display screen shows the flight scene with the initially set flight speed and flight angle. At the same time, the water pump in the water supply component starts and sends water from the water supply tank into the simulator through the pump pipe at a fixed output power. Water drips into the simulation tank through the drain hole to simulate the effect of rain. The trainee watches the screen through the simulator and the perspective changes to the scene of flying in the rain. S2: The motor in the water pumping assembly outputs power to the first roller with its initial output power. The first roller rotates, causing the water dripping on it to be splashed onto the glass plate. At the same time, using the transmission effect of the first rubber wheel and the first belt, the upper roller transmits power to the lower roller. The lower roller rotates synchronously, splashing the water flowing down from the drainage trough onto the glass plate again. The rotation of the upper and lower rollers splashes water droplets onto the glass plate, creating the effect of heavy rain falling on the windows of an airplane cockpit. S3: While the upper and lower rollers are rotating and spraying water droplets, the transmission shaft in the transmission assembly transmits the power of the lower roller to the transmission disc. During the rotation of the transmission disc, the rocker arm is continuously pushed. The push rod moves up and down under the swinging action of the rocker arm, causing the push plate to continuously push the airbag in the air supply assembly. When the push plate pushes down, the second electric valve is closed. The gas in the airbag is discharged into the water supply chamber through the exhaust pipe. The water in the chamber removes some impurities. The push plate moves down until the third contact switch is energized, and the second electric valve opens. At this time, all the gas in the airbag is discharged. At the same time, the push plate moves up, pulling the airbag to extend. Outside air flows back into the airbag through the second electric valve. When the push plate moves up until the second contact switch is energized, the second electric valve closes again. This process is repeated. S4: The air flowing into the water supply chamber enters the filter cartridge through the connecting pipe, passes through the activated carbon layer inside, removes some of the remaining impurities, and then flows into the air chamber of the blower assembly through the air inlet pipe. S5: At the same time, by utilizing the meshing transmission of the active gear and the driven gear, in conjunction with the transmission action of the second rubber wheel and the second belt, the power of the first roller is transmitted to the fan. The fan rotates at high speed, accelerating the gas that entered the air chamber in the previous step and expelling it from the air outlet into the simulator's simulation chamber, creating a blowing effect. The high-speed airflow flows across the surface of the glass plate, blowing water droplets and water flow laterally away, simulating the flow of water droplets on the airplane window during high-altitude flight. S6: Water flowing from the drain trough enters the water tank below. At this time, the first electric valve is closed, and water cannot flow out from the drain pipe. As the water in the water tank increases, the weight of the water tank increases, and it moves downwards closer to the balance platform, compressing the return spring and stretching it. When the tension sensor detects that the tension value of the return spring has reached the threshold, it sends a signal to the control unit of the flashlight. The flashlight emits a momentary flash of light to simulate the effect of lightning. After the water tank moves further down until the first contact switch is energized, the sound generator starts to simulate thunder and sends a signal to the first electric valve. The first electric valve opens, and the water in the water tank flows into the water supply chamber through the seepage pipe and the drain pipe, waiting for the next circulation pump. S7: When the trainee pushes the second push handle by hand, the second torque sensor detects the change in torque of the second spring and converts the change into an electrical signal, which is transmitted to the control console in real time. The control console adjusts the output of the display screen, that is, adjusts the simulated flight speed. At the same time, it also sends a signal to the motor control unit of the water-lifting assembly. When the speed is increased, the motor output power increases, the speed at which the upper and lower rollers throw water droplets is faster, and the frequency of simulated water droplets hitting the aircraft window increases. In addition, the fan in the blowing assembly rotates faster, simulating a greater relative wind speed. Conversely, when the speed is decreased, the speed at which the upper and lower rollers throw water droplets is slower, and the fan rotation speed is also slower. S8: When the flight screen displays poor visibility or the simulated rain is too heavy, the trainee can manually push the first push handle. The first torque sensor detects the torque change of the first spring and converts the change into an electrical signal, which is transmitted to the control console in real time. The control console adjusts the output of the display screen, that is, adjusts the angle of the simulated flight (raise or lower). The control console converts the torque signals transmitted by the first and second torque sensors into corresponding flight angle and flight speed values. Based on the initial flight speed and angle, it calculates the time to fly above the cloud layer and sends a signal to the water pump control unit, causing the water pump to stop running after the corresponding time, simulating the state of flying above the cloud layer in rainy weather.

[0016] The beneficial effects of this invention are: 1. By using the water-lifting component to output power onto the water droplets, the effect of splashing water droplets and water spray is created. The splashing force, speed, sound and range of the water hitting the glass plate of the simulator can be greater, which is more consistent with the scene of high-speed flight in the rain and the simulation is more realistic. 2. Set up a wind blowing component on the simulator and use the power generated by the water lifting component to drive it. This can simulate the effect of wind blowing water droplets falling on the aircraft window during high-altitude and high-speed flight, and make the simulation of the impact of rain on the flight visibility more realistic. 3. By adjusting the output power of the water-spraying and wind-blowing components through the speed control component, different states of raindrop splashing and flowing can be achieved at different flight speeds, making the simulation training more diverse and more realistic. 4. By collecting the output signals of the ascent and descent control components and the speed control components through the console, and using the initial flight speed and angle as calculation parameters, the time point for entering the cloud flight can be calculated, and the screen image can be adjusted accordingly. This can train trainees to choose to fly above the cloud layer to avoid the impact of rain when heavy rain greatly obstructs their vision. 5. By using the state changes of the water tank in the water circulation component as a signal source, the sound and light simulation component can be activated. Lightning and thunder can be simulated in sequence according to a certain pattern, making the simulated rainy weather environment more realistic. 6. The power of the water pumping component is converted into the power for conveying gas in the blowing component, eliminating the need for other power sources and making the equipment more economical to operate; 7. By first flushing air into the water supply chamber, water can be used as a filter material to absorb some air impurities, reducing the amount of dust and impurities carried into the simulator by the air. 8. Using a filter cartridge as another filtration system after the water supply tank can further remove dust and impurities from the air that floats to the surface, improving air cleanliness.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-13This invention provides an embodiment of a flight training simulation device, comprising a console 1, a control cabinet 2 mounted on one side of the console 1, a simulator 3 mounted on the control cabinet 2, and a display screen 4. The display screen 4 displays simulated flight images. It also includes a seat 5 mounted on the console 1, a water supply assembly mounted inside the control cabinet 2, and a lift control assembly and a speed control assembly mounted on the console 1. The water supply assembly supplies water to the simulator 3, which simulates the impact of rainy weather on flight visibility. Both the lift control assembly and the speed control assembly are signal-connected to the control unit of the display screen 4. The lift control assembly controls the display screen 4 to simulate flight ascent or descent, and the speed control assembly controls the display screen 4 to simulate flight descent. The simulator displays the speed increase or decrease of the simulator. Control console 1 is used to collect the output signals of the lift control component and the speed control component, and send the signals to the water supply component. Simulator 3 includes two parallel glass plates, several drainage holes on the top of simulator 3, and a drainage trough 901 on the bottom of simulator 3. The two glass plates form a simulation chamber. Control cabinet 2 is equipped with a water circulation component, and simulator 3 is equipped with a water lifting component and a blower component. The water circulation component is used to input water from simulator 3 into the water supply component, and the water lifting component is used to spray water from simulator 3. The speed control component is signal-connected to the water lifting component, and the blower component is used to deliver gas into simulator 3. When the simulated flight speeds up, the water lifting component increases the spraying speed of water, and the blower component increases the gas delivery speed.When the simulated flight decelerates, the water spray component reduces the water spray speed, and the air blowing component reduces the gas delivery speed. (Current raindrop simulation uses a top-down dripping method, and the water droplets flow slowly downwards on the glass plate. This differs from the flow of water droplets on the aircraft window during high-altitude flight. At high altitudes, strong winds and high aircraft speeds cause raindrops falling on the window to be blown to one side before they have time to flow downwards. The impact of these two water droplet flow patterns on visibility differs.) After the trainee sits in seat 5, they control the ascent and descent control component and the speed control component with their left and right hands respectively. Simultaneously, the water supply component pumps water into simulator 3, and the water flows through the exhaust system on simulator 3. Water drips into the simulated cabin between two glass panels (the front and rear glass panels of simulator 3 are made of the same material as real aircraft windows; simulator 3 is surrounded by other metal or glass materials to form a frame structure, enclosing the simulated cabin; drainage holes are located at the top of the frame, and water drips from the drainage holes into the simulated cabin; drainage channel 901 is located at the bottom of the frame, and the dripping water flows away along drainage channel 901). This simulates the effect of rain affecting flight visibility. The water-spraying component acts on the dripping water droplets and the water flowing along drainage channel 901, spraying water droplets onto the glass panels to simulate the effect of rain falling on the aircraft window (in actual applications, windshield wipers can also be set in simulator 3, refer to announcement number CN118116261A). The technical solution involves trainees controlling the start and stop of the system, and scraping away water droplets on the glass plate as needed. Water flows into the water circulation component through the drainage channel 901, replenishing the water supply component. During the dripping process, the water-lifting component simultaneously transmits power to the blowing component, inputting a high-speed airflow into simulator 3 to blow away the water droplets on the glass plate, simulating the impact of wind on raindrops during high-altitude flight. (Flight simulation training generally simulates more severe scenarios than real-world conditions, enhancing pilots' reaction time, judgment, and mental fortitude during regular training. Since it doesn't rain above clouds, in reality, to reduce the impact of heavy rain on flight safety, pilots can fly above clouds to avoid rain, depending on the situation.) Through training... The pilot's use of the ascent and descent control components and speed control components, combined with display screen 4 (showing changes in the flight image during adjustments to flight angle and speed), water-spraying components (increasing output power, water spray speed, and frequency as flight speed increases), and air-blowing components (increasing output power, air delivery speed, and flight speed), allows the control console 1 to collect signal changes from the ascent and descent control components. Using the initial flight angle and speed as additional parameters, the console calculates the time it takes for the aircraft to fly above the cloud layer. This calculation sends a feedback signal to the water supply component's control unit, stopping water supply and simulating the aircraft flying above the cloud layer to avoid rain. This training aims to reduce visibility obstruction and improve pilots' operational awareness for rainy weather flight.

[0021] Please see Figures 1-5 In this embodiment, the water supply assembly includes a water supply tank 601 and a water pump 602 installed in the control cabinet 2. The inlet of the water pump 602 is connected to the water supply tank 601, and the outlet of the water pump 602 is connected to the simulator 3 by a pump pipe 603. The water pump 602 is used to transport water from the water supply tank 601 to the simulator 3, and the drain hole is used to drip water onto the glass plate of the simulator 3. After the trainee sits in the seat 5, the water pump 602 starts immediately. (Depending on actual needs, detection devices such as pressure sensors can be installed in the seat 5 to monitor the water pump 602.) The start control of 2 sends a command signal, which can also keep the water pump 602 running continuously. The water pump 602 draws water out of the water supply tank 601 and delivers the water to the simulator 3 through the pump pipe 603. The water flows out from the drain hole into the simulation tank to simulate the rain effect. (In actual applications, a movable plate with holes can be set above or below the drain hole. The reciprocating movement of the movable plate can align the holes with the drain hole or close the drain hole. Refer to the technical solution disclosed in announcement number CN118116261A to simulate the water droplet effect.)

[0022] Please see Figures 1-3 and Figures 10-13In this embodiment, the lifting control assembly includes a first base 701 mounted on the console 1, a first bearing 702 movably connected within the first base 701, a first push handle 703 fixedly connected to the first bearing 702, a first spring 704 mounted between the first bearing 702 and the first base 701, and a first torque sensor 705 mounted on the first spring 704. The first torque sensor 705 is used to detect the torque of the first spring 704 and send a signal to the control unit of the display screen 4; the speed control assembly includes a second base 801 mounted on the console 1, a first push handle 703 fixedly connected to the first bearing 702 ... push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 fixedly connected to the first bearing 702, a first push handle 703 The system includes a second shaft seat 802 connected within the second base 801, a second push handle 803 fixedly connected to the second shaft seat 802, a second spring 804 installed between the second shaft seat 802 and the second base 801, and a second torque sensor 805 installed on the second spring 804. The second torque sensor 805 detects the torque of the second spring 804 and sends a signal to the control unit of the display screen 4. When the trainee pushes the second push handle 803, the second torque sensor 805 detects the change in torque of the second spring 804 and sends a signal to the control console 1 based on the change value, which is then adjusted by the control console 1. The display screen 4 (i.e., the screen display is adjusted to match the simulated flight speed) simultaneously sends a signal to the control unit of the water-lifting assembly. When the speed increases, the output power of the water-lifting assembly is increased, and the output power of the blower assembly also increases synchronously. Conversely, when the speed decreases, the control console 1 adjusts the display screen 4 to decrease the output power of the water-lifting and blower assemblies. When the trainee pushes the first push handle 703, the first torque sensor 705 detects the torque change of the first spring 704 and sends a signal to the control console 1 based on the change value, which then adjusts the control console 1. The entire display screen 4 (that is, the screen display is adjusted to match the screen corresponding to the simulated flight angle, flying upwards or downwards) is displayed. The control console 1 simultaneously collects the detection data of the first torque sensor 705 and the second torque sensor 805 during the corresponding time period, and calculates the time to fly above the cloud layer by combining the initial flight speed and angle data. It then sends a signal to the control unit of the water pump 602 in the water supply assembly, causing the water pump 602 to stop running after the corresponding time. This simulates the state in rainy weather where the pilot chooses to fly above the cloud layer to reduce the impact of rain on visibility, and the impact of rain on visibility is eliminated.

[0023] Please see Figures 1-2 and Figures 4-6In this embodiment, the water circulation assembly includes a water tank 902 housed in the control cabinet 2, a balance platform 903 fixed in the control cabinet 2, a seepage pipe 904 connected to the lower end of the water tank 902, a first electric valve 905 installed on the seepage pipe 904, a drain pipe 906 fixedly connected to the outlet end of the first electric valve 905, and a cover plate 907 fixedly connected to the lower end of the drain pipe 906. The water tank 902 is located below the drain trough 901, and the cover plate 907 is installed on the upper end of the water supply chamber 601. When the first electric valve 905 is opened, water in the water tank 902 flows into the water supply chamber 601 along the seepage pipe 904, the first electric valve 905, and the drain pipe 906. When the first electric valve 905 is closed, the water level in the water tank 902 continuously rises. An audio-visual simulation assembly is installed on the water circulation assembly. The audio-visual simulation assembly is used to simulate lightning and thunder during rain. The audio-visual simulation assembly includes a guide fixedly connected to the lower end of the water tank 902. The simulator 3 includes a guide rod 1001, a return spring 1002 mounted on the guide rod 1001, a tension sensor 1003 mounted on the balance platform 903, a flashlight 1004 mounted in the simulator 3, and a sound generator 1006 mounted on the balance platform 903. The guide rod 1001 is slidably connected to the balance platform 903. The water tank 902 can move up and down along the axial direction of the guide rod 1001. One end of the return spring 1002 is connected to the guide rod 1001, and the other end is connected to the tension sensor 1003. The tension sensor 1003 is used to detect the tension of the return spring 1002. The flashlight 1004 is used to simulate lightning, and the sound generator 1006 is used to simulate thunder. A first contact switch 1005 is installed at the bottom of the water tank 902, and another first contact switch 1005 is installed at the top of the balance platform 903. When the water tank 902 moves down, the tension sensor 1003 sends a signal to the control unit of the flashlight 1004.When the water tank 902 moves downwards until the two first contact switches 1005 are energized, the sounder 1006 emits a thunderous sound. With no water in the water tank 902, the return spring 1002 lifts the water tank 902, and the first contact switches 1005 are in the open state. At this time, the first electric valve 905 is closed, and the tension sensor 1003 detects zero tension in the return spring 1002. Water flowing from the drain trough 901 first enters the lower water tank 902, and water cannot flow from the drain trough. Water flows out through pipe 906 and the first electric valve 905. As the water in the water tank 902 increases, its weight increases, causing it to gradually move downwards towards the balance platform 903. The movement of the guide rod 1001 stretches the return spring 1002. When the tension sensor 1003 detects that the tension of the return spring 1002 has reached a threshold, it sends a signal to the control unit of the flashlight 1004. The flashlight 1004 then emits a brief flash of light within the simulator 3, simulating the effect of lightning. As water continues to flow into the water tank 902, after the water tank 902 moves further down until the first contact switch 1005 is energized, a signal is sent to the control unit of the sound generator 1006 (i.e., the small speaker). The sound generator 1006 activates the simulated thunder sound. At the same time, the tension sensor 1003 detects that the tension value of the return spring 1002 has reached another threshold, and sends a signal to the control unit of the first electric valve 905. The first electric valve 905 opens, and the water in the water tank 902 flows through the seepage pipe 904 and... The drain pipe 906 flows into the water supply chamber 601, awaiting the next circulation pump. As water continuously flows out of the water tank 902 (the outflow rate is faster than the inflow rate), the weight of the water tank 902 decreases, causing the return spring 1002 to contract and gradually lift the water tank 902. When the tension sensor 1003 detects that the tension value of the return spring 1002 has returned to zero, it sends a signal again to the control unit of the first electric valve 905. The first electric valve 905 closes, and the water tank 902 returns to the water storage state.

[0024] Please see Figures 1-5 and Figures 7-9In this embodiment, the water-lifting assembly includes an upper roller 1101 movably connected to the top of the simulation chamber, a lower roller 1102 movably connected to the bottom of the simulation chamber, two first rubber wheels 1103 respectively connected to the upper roller 1101 and the lower roller 1102, a first belt 1104 drivingly connected between the two first rubber wheels 1103, and a motor 1105 mounted on the simulator 3. The first rubber wheels 1103 on the upper roller 1101 are fixedly connected to the output end of the motor 1105. The upper roller 1101 is positioned below the drain hole, and the lower roller 1102 is positioned above the drain trough 901. The motor 1105 drives the upper roller 1101 to rotate. The first rubber wheels 1103 and the first belt 1104 transmit the power of the upper roller 1101 to the lower roller 1102. The upper roller 1101 is used to spray the water dripping from the drain hole, and the lower roller 1102 is used to spray the water in the drain trough 901. (During high-altitude, high-speed flight, raindrops will hit the aircraft window in large quantities. However, water dripping directly downwards does not simulate the effect of raindrops splashing onto the window. By using the rotating upper roller 1101 and lower roller 1102 to act on the water droplets and water flow, centrifugal force is used to create a splashing effect on the water droplets, thus simulating the effect of raindrops splashing onto the window.) The motor 1105 controls the rotation of the upper roller 1101. Water droplets falling on the upper roller 1101 through the drain hole will be splashed onto the glass plate to both sides. At the same time, under the transmission action of the first rubber wheel 1103 and the first belt 1104, the power of the upper roller 1101 is transmitted to the lower roller 1102. The lower roller 1102 rotates synchronously, acting on the water flowing through the drain trough 901, and splashing some of the water upwards onto the glass plate. The upper roller 1101 and lower roller 1102 work together to simulate the effect of a large amount of rainwater splashing onto the aircraft window on a rainy day.

[0025] Please see Figures 1-2 and Figures 4-5 , Figures 7-8In this embodiment, the blowing assembly includes a wind chamber disposed on one side of the simulator 3, a plurality of fans 1501 disposed within the wind chamber, second rubber wheels 1502 fixedly connected to each fan 1501, a second belt 1503 drivingly connected to each second rubber wheel 1502, a driving gear 1504 fixedly connected to the upper roller 1101, a driven gear 1505 fixedly connected to one of the second rubber wheels 1502, and an air outlet 1506 opened on one side of the wind chamber. The second rubber wheels 1502 are movably connected to the wall panel of the wind chamber. The driving gear 1504 meshes with the driven gear 1505. The second rubber wheels 1502 and the second belt 1503 are used to transmit the power of the upper roller 1101 to each fan 1501. The fans 1501 are used to accelerate the gas in the wind chamber to be discharged from the air outlet 1506 into the simulation chamber. The upper roller 1101 rotates... Simultaneously, power is output to the drive gear 1504, which drives the driven gear 1505 to rotate (the diameter of the driven gear 1505 is much smaller than that of the drive gear 1504, meaning that the time for the driven gear 1505 to rotate one revolution is much shorter than that for the drive gear 1504 to rotate one revolution). The driven gear 1505 then outputs power to one of the second rubber wheels 1502. Through the transmission action of the second rubber wheel 1502 and the second belt 1503, each second rubber wheel 1502 and its fan 1501 rotate at high speed, accelerating the airflow in the air chamber and discharging it from the air outlet 1506 into the simulator 3 (in actual use, a drain outlet can be set at the bottom of the air chamber, connected to the water supply chamber 601, to drain the water splashed into the air chamber), creating a blowing effect on the water droplets on the glass plate, simulating the effect of wind on water droplets on the aircraft window during high-altitude flight.

[0026] Please see Figures 1-5 and Figures 8-9In this embodiment, a transmission assembly is installed on the water pumping assembly. The transmission assembly includes a transmission shaft 1201 fixedly connected to one end of the lower roller 1102, a transmission disc 1202 fixedly connected to the transmission shaft 1201, a rocker arm 1203 movably connected at one end to the eccentric position of the transmission disc 1202, a push rod 1204 movably connected to the other end of the rocker arm 1203, and a push plate 1205 installed on the push rod 1204. The transmission shaft 1201 is used to transmit the power of the lower roller shaft to the transmission disc 1202. The transmission disc 1202 is used to drive the rocker arm 1203 to push the push rod 1204 and the push plate 1205 to move up and down reciprocally. An air supply assembly is installed in the control cabinet 2. The air supply assembly includes an airbag cover 1301 installed in the control cabinet 2, a partition 1302 fixedly connected to the airbag cover 1301, and a second air inlet installed at the bottom of the airbag cover 1301. An electric valve 1303, an exhaust pipe 1304 fixedly connected at one end to the airbag cover 1301, and a push plate 1205 fixedly connected above the airbag cover 1301 are included. The second electric valve 1303 is used to open or close the air inlet at the bottom of the airbag cover 1301. The other end of the exhaust pipe 1304 is connected to the water supply tank 601 and is used to input the gas inside the airbag cover 1301 into the water supply tank 601. A second contact switch 1305 is installed on the push plate 1205 and at corresponding positions on the control cabinet 2. A third contact switch 1306 is installed on the push plate 1205 and on the partition plate 1302. When the push plate 1205 moves down until the third contact switch 1306 is energized, the second electric valve 1303 opens the air inlet. When the push plate 1205 moves up until the second contact switch 1305 is energized, the second electric valve 1303 closes the air inlet.A filter assembly is installed on the water circulation assembly. The filter assembly includes a connecting pipe 1401 fixedly connected at one end to the cover plate 907, a filter cartridge 1402 installed at the lower end of the balance platform 903, and an air inlet pipe 1403 connected at one end to the filter cartridge 1402. The other end of the connecting pipe 1401 is connected to the filter cartridge 1402, and the other end of the air inlet pipe 1403 is connected to the air chamber of the blower assembly. The connecting pipe 1401 is used to input the gas in the water supply chamber 601 into the filter cartridge 1402, and the air inlet pipe 1403 is used to input the air in the filter cartridge 1402 into the blower assembly. The filter cartridge 1402 is equipped with... There is an activated carbon layer used to filter the gas entering the filter cartridge 1402. As the lower roller 1102 rotates, it transmits power to the transmission disc 1202 via the transmission shaft 1201 in the transmission assembly. The transmission disc 1202 rotates, continuously swinging the rocker arm 1203. The push rod 1204 reciprocates up and down under the swinging action of the rocker arm 1203, which also causes the push plate 1205 to reciprocate up and down continuously. When the push plate 1205 moves downward, it pushes the airbag shroud 1301 in the air supply assembly. At this time, the second electric valve 1303 is in the closed state, and the airbag shroud 1301... The gas is discharged into the water supply tank 601 through the exhaust pipe 1304, passing through the water and removing some impurities (because these impurities remain in the water, the water inlet of the water pump 602 needs to be equipped with a filter structure to prevent impurities from entering the water supply channel of the water pump 602). This continues until the push plate 1205 moves down close to the partition 1302, energizing the third contact switch 1306 and sending a signal to the control unit of the second electric valve 1303. The second electric valve 1303 opens, at which point all the gas in the airbag 1301 is discharged. Then, the push plate 1205 moves up, pulling the airbag 1301. As 301 extends, outside air flows back into the airbag cover 1301 through the second electric valve 1303. When the push plate 1205 moves upward until the second contact switch 1305 is energized, the second electric valve 1303 closes again. The air entering the water supply chamber 601 enters the filter cartridge 1402 along the connecting pipe 1401 (because the fan 1501 is constantly rotating, a negative pressure is formed in the air chamber, so the air is always in a state of tending to flow into the air chamber). After passing through the activated carbon layer in the filter cartridge 1402, impurities in the water are further intercepted, preventing impurities and dust from being blown into the simulator 3.

[0027] Please see Figures 1-13 In this embodiment, the present invention provides a method for flight training, employing a flight training simulation device as described above, comprising the following steps: S1: The trainee first sits in seat 5, with both hands on the first push handle 703 of the lift control component and the second push handle 803 of the speed control component. The simulator is activated, and the display screen 4 simulates the flight scene with the initially set flight speed and flight angle. At the same time, the water pump 602 in the water supply component is activated. With a fixed output power, the water pump 602 in the water supply tank 601 is sent to the simulator 3 through the pump pipe 603. Water drips into the simulation tank through the drain hole to simulate the effect of rain. The trainee watches the screen 4 through the simulator 3, and the perspective changes to the scene of flying in the rain. S2: The motor 1105 in the water pumping assembly outputs power to the first roller with its initial output power. The first roller rotates, causing the water dripping on it to be splashed onto the glass plate. At the same time, using the transmission effect of the first rubber wheel 1103 and the first belt 1104, the upper roller 1101 transmits power to the lower roller 1102. The lower roller 1102 rotates synchronously, splashing the water flowing down from the drainage trough 901 onto the glass plate again. The rotation of the upper roller 1101 and the lower roller 1102 splashes water droplets onto the glass plate, creating the effect of heavy rain falling on the windows of an aircraft cockpit. S3: While the upper roller 1101 and lower roller 1102 are rotating and spraying water droplets, the transmission shaft 1201 in the transmission assembly transmits the power of the lower roller 1102 to the transmission disc 1202. During the rotation of the transmission disc 1202, it continuously pushes the rocker arm 1203. The push rod 1204 moves up and down reciprocally under the swinging action of the rocker arm 1203, causing the push plate 1205 to continuously push the airbag cover 1301 in the air supply assembly. When the push plate 1205 pushes downward, the second electric valve 1303 is in the closed state, and the gas in the airbag cover 1301 passes through... The exhaust pipe 1304 discharges into the water supply tank 601. The water passing through the tank removes some impurities. The push plate 1205 moves down until the third contact switch 1306 is energized, and the second electric valve 1303 opens. At this time, all the gas in the airbag cover 1301 is discharged. At the same time, the push plate 1205 moves up, pulling the airbag cover 1301 to extend. Outside air flows back into the airbag cover 1301 through the second electric valve 1303. When the push plate 1205 moves up until the second contact switch 1305 is energized, the second electric valve 1303 closes again. This process is repeated in a cycle. S4: The air flowing into the water supply chamber 601 enters the filter cartridge 1402 through the connecting pipe 1401, passes through the activated carbon layer inside, removes some of the remaining impurities, and then flows into the air chamber of the blower assembly through the air inlet pipe 1403. S5: At the same time, by utilizing the meshing transmission of the drive gear 1504 and the driven gear 1505, and in conjunction with the transmission action of the second rubber wheel 1502 and the second belt 1503, the power of the first roller is transmitted to the fan 1501. The fan 1501 rotates at high speed, accelerating the gas that entered the air chamber in the previous step and expelling it from the air outlet 1506 into the simulation chamber of the simulator 3, forming a blowing effect. The high-speed airflow flows across the surface of the glass plate, blowing the water droplets and water flow laterally away, simulating the flow of water droplets on the airplane window during high-altitude flight. S6: Water flowing out of the drain trough 901 enters the water tank 902 below. At this time, the first electric valve 905 is closed, and water cannot flow out from the drain pipe 906. As the water in the water tank 902 increases, the weight of the water tank 902 increases, and it moves downwards closer to the balance platform 903, pressing the return spring 1002 to stretch. When the tension sensor 1003 detects that the tension value of the return spring 1002 has reached the threshold, it sends a signal to the control unit of the flash lamp 1004. The flash lamp 1004 emits a momentary flash of light to simulate the effect of lightning. After the water tank 902 moves further down until the first contact switch 1005 is energized, the sound generator 1006 starts to simulate thunder and sends a signal to the first electric valve 905. The first electric valve 905 opens, and the water in the water tank 902 flows into the water supply chamber 601 through the seepage pipe 904 and the drain pipe 906, waiting for the next circulation pump. S7: When the trainee pushes the second push handle 803 by hand, the second torque sensor 805 detects the change in torque of the second spring 804 and converts the change into an electrical signal, which is transmitted to the control console 1 in real time. The control console 1 adjusts the output screen of the display screen 4, that is, adjusts the simulated flight speed. At the same time, it also sends a signal to the motor 1105 control unit of the water-lifting assembly. When the speed is increased, the output power of the motor 1105 increases, and the speed at which the upper roller 1101 and the lower roller 1102 throw water droplets is also faster, and the frequency of simulated water droplets hitting the aircraft window increases. In addition, the fan 1501 in the blowing assembly also rotates faster, simulating a greater relative wind speed. Conversely, when the speed is decreased, the speed at which the upper roller 1101 and the lower roller 1102 throw water droplets is slower, and the rotation speed of the fan 1501 is also slower. S8: When the flight screen on display 4 shows poor visibility or the simulated rain is too heavy, the trainee can push the first push handle 703 by hand. The first torque sensor 705 detects the torque change of the first spring 704 and converts the change into an electrical signal, which is transmitted to the control console 1 in real time. The control console 1 adjusts the output screen of display 4, that is, adjusts the angle of simulated flight (raise or lower). The control console 1 converts the torque signals transmitted by the first torque sensor 705 and the second torque sensor 805 into corresponding flight angle and flight speed values. Based on the initial flight speed and angle, it calculates the time to fly above the cloud layer and sends a signal to the control unit of the water pump 602, causing the water pump 602 to stop running after the corresponding time, simulating the state of flying above the cloud layer in rainy weather.

10. A method for flight training, characterized in that: The simulation device for flight training as claimed in claim 9 comprises the following steps: S1: The trainee first sits in the seat (5), and holds the first push handle (703) of the lifting control component and the second push handle (803) of the speed control component with both hands respectively. The simulation device is started, and the display screen (4) simulates and displays the flight picture at the initially set flight speed and flight angle. At the same time, the water pump (602) in the water supply component is started, and the water pump (602) in the water supply tank (601) is sent to the simulator (3) through the water pump pipe (603) with a fixed output power, and the water drips into the simulation tank through the drainage hole, simulating the effect of rain. The trainee watches the screen (4) through the simulator (3), and the viewing angle changes to the picture of flying in the rain. S2: The motor (1105) in the water-lifting assembly outputs power to the first roller body at the initial output power, and the first roller body rotates, causing the water dripping thereon to be thrown around and onto the glass plate. At the same time, the upper roller body (1101) transmits power to the lower roller body (1102) by utilizing the transmission effect of the first rubber wheel (1103) and the first belt (1104), and the lower roller body (1102) rotates synchronously, and the water flowing down from the drainage groove (901) is thrown around again onto the glass plate. The rotation of the upper roller body (1101) and the lower roller body (1102) throws water drops onto the glass plate, creating an effect of heavy rain falling on the windows of the cockpit of an aircraft; S3: While the upper roller body (1101) and the lower roller body (1102) are rotating and spraying water droplets, the transmission shaft (1201) in the transmission assembly transmits the power of the lower roller body (1102) to the transmission disc (1202). During the rotation of the transmission disc (1202), the rocker arm (1203) is continuously pushed. The push rod (1204) moves up and down reciprocatingly under the swinging action of the rocker arm (1203), prompting the push plate (1205) to continuously push the airbag cover (1301) in the air supply assembly. When the push plate (1205) pushes downward, the second electric valve (1303) is in a closed state, and the gas in the airbag cover (1301) is released. The gas is discharged into the water supply tank (601) through the exhaust pipe (1304), passes through the water therein, removes some impurities, and the push plate (1205) moves downward until the No. 3 contact switch (1306) is energized, and the second electric valve (1303) is opened. At this time, all the gas in the airbag cover (1301) is discharged, and at the same time, the push plate (1205) moves upward, pulling the airbag cover (1301) to extend, and the outside air flows into the airbag cover (1301) again through the second electric valve (1303). When the push plate (1205) moves upward until the second contact switch (1305) is energized, the second electric valve (1303) is closed again, and this process is repeated; S4: The air flowing into the water supply chamber (601) enters the filter cartridge (1402) through the communication pipe (1401), passes through the activated carbon layer inside the filter cartridge, removes some of the remaining impurities again, and then flows into the air chamber of the blowing assembly through the air inlet pipe (1403); S5: At the same time, the driving gear (1504) and the driven gear (1505) are meshed and driven together with the second rubber wheel (1502) and the second belt (1503), so that the power of the first roller is transmitted to the fan (1501). The fan (1501) rotates at a high speed, accelerating the gas entering the wind chamber in the previous step to be discharged from the air outlet (1506) into the simulation chamber of the simulator (3), thereby forming a blowing effect. The high-speed air flow flows through the surface of the glass plate, blowing the water droplets and water flow away laterally, simulating the flow state of water droplets on the aircraft window in the rain during high-altitude flight; S6: Water flowing out of the drain trough (901) enters the water tank (902) below. At this time, the first electric valve (905) is in a closed state, and water cannot flow out of the drain pipe (906). As the water in the water tank (902) continues to increase, the weight of the water tank (902) continues to increase, and moves downward to approach the balance platform (903), and compresses the return spring (1002) to stretch. When the tension sensor (1003) detects that the tension value of the return spring (1002) reaches the threshold, it sends a signal to A control unit of the flashlight (1004), the flashlight (1004) emits a momentary light to simulate the effect of lightning, and after the water tank (902) moves further downward until the first contact switch (1005) is energized, the sound generator (1006) starts to simulate thunder and simultaneously sends a signal to the first electric valve (905), the first electric valve (905) opens, and the water in the water tank (902) flows into the water supply tank (601) through the seepage pipe (904) and the drainage pipe (906), waiting for the next circulation pump water; S7: When the trainee pushes the second push handle (803) by hand, the second torque sensor (805) detects the change in torque of the second spring (804), and converts the change value into an electrical signal and transmits it to the control console (1) in real time. The control console (1) adjusts the output screen of the display screen (4), that is, adjusts the speed of the simulated flight. At the same time, it also sends a signal to the motor (1105) control unit of the water-lifting component. When the speed is increased, the output power of the motor (1105) increases, the speed of the water droplets thrown by the upper roller (1101) and the lower roller (1102) also increases, and the frequency of the simulated water droplets hitting the aircraft window increases. In addition, the fan (1501) in the blowing component also rotates faster, and the simulated relative wind speed is greater. On the contrary, when the speed is reduced, the speed of the water droplets thrown by the upper roller (1101) and the lower roller (1102) slows down, and the rotation speed of the fan (1501) also slows down. S8: When the flight picture on the display screen (4) shows that the flight visibility is poor, or the simulated rain is too heavy, the trainee pushes the first push handle (703) by hand, and the first torque sensor (705) detects the torque change of the first spring (704), and converts the change value into an electrical signal and transmits it to the control console (1) in real time. The control console (1) adjusts the output picture of the display screen (4), that is, adjusts the angle of the simulated flight. The control console (1) converts the torque signals transmitted by the first torque sensor (705) and the second torque sensor (805) into corresponding flight angle values ​​and flight speed values, and calculates the time of flying above the cloud layer based on the initial flight speed and angle, and sends a signal to the control unit of the water pump (602) to stop the water pump (602) after the corresponding time, so as to simulate the state of flying above the cloud layer in rainy days.
