Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be arbitrarily combined with each other.

[0016] As explained in the background section, the role of trainer aircraft is to cultivate pilots' flying skills through flight control training systems. However, for some flight trainees, there are still problems such as difficulties in technical transition, lack of experience, and difficulty in adapting when transitioning from simulator training to actual flight training on trainer aircraft.

[0017] To address the aforementioned problems, this invention proposes a flight control perception training system, which is installed in an embedded flight training experience cabin of a trainer aircraft. This system allows trainees to experience flight before actual flight training, serving as a transitional phase from simulator training to real flight. After trainees have become basically accustomed to flight control perception in the trainer aircraft experience cabin, they can then move to the cockpit to directly participate in piloting the aircraft for real flight control training. Using the flight control perception training system provided by this invention, trainees can improve their flight control capabilities by experiencing and perceiving the real process of controlling the aircraft's attitude using the control wheel, stick, and pedals.

[0018] The present invention provides the following specific embodiments, which can be combined with each other. For the same or similar concepts or processes, they may not be described again in some embodiments.

[0019] like Figure 1 and Figure 2 As shown, the flight control perception training system provided by the present invention is installed in the flight training experience cabin of a trainer aircraft. The flight control perception training system includes two subsystems: a drive control subsystem and an instrument display subsystem.

[0020] like Figure 1 As shown, the drive control subsystem includes: a motor controller that communicates with a host computer in the cockpit, a multi-channel simulated electric mechanism electrically connected to the motor controller, and a multi-channel simulated control component that is connected to the multi-channel simulated electric mechanism in a one-to-one correspondence.

[0021] In the drive control subsystem, the motor controller is used to receive the target displacement signals of each simulated control component sent by the host computer, and send corresponding drive signals to each channel simulated electric mechanism. The target displacement signal of each simulated control component is the displacement signal of the corresponding control component in the cockpit. The motor controller is also used to receive the displacement feedback value of each channel simulated electric mechanism based on the actual displacement stroke feedback of the simulated control component, compare it with the target displacement signal to determine whether each simulated control component is adjusted in place, and stop sending drive signals to each channel simulated electric mechanism after adjustment is in place.

[0022] like Figure 2 As shown, the instrument display subsystem includes an external view display module and a cockpit synchronous display module; the external view display module displays the view outside the aircraft window, while the cockpit synchronous display module displays flight status information, the status of various systems in the aircraft, and the display of different mission screens.

[0023] In one implementation of this invention, each channel of the drive control subsystem includes a simulated electric mechanism comprising: a permanent magnet brushless DC motor, a reducer assembly, a lead screw motion pair, a potentiometer sensor, a slip mechanism, and an extreme position switch.

[0024] In this implementation, a permanent magnet brushless DC motor is responsible for power output; the reducer assembly is connected to the output shaft of the brushless motor, reducing the motor output speed to the actual operating range and increasing the output torque.

[0025] The lead screw motion pair is connected to the output shaft of the brushless motor, converting the rotational motion of the motor output shaft into the linear motion of the lead screw motion pair nut and transmitting torque. The nut of the lead screw motion pair serves as the output shaft of the simulated electric mechanism and is connected to the corresponding simulated control component. The potentiometer sensor is interconnected with the output shaft of the electric mechanism and is used to collect the voltage signal corresponding to the extension or retraction stroke of the output shaft of the electric mechanism.

[0026] The limit position switch is set at the extreme position of the lead screw pair and is used to disconnect the motor power supply when the lead screw pair moves to the extreme position.

[0027] The slippage mechanism is installed between the output shaft of the brushless motor and the lead screw kinematic pair, and is used to disengage the output shaft of the brushless motor from the lead screw kinematic pair when the load is too large.

[0028] In one implementation of this invention, each channel's simulated electric mechanism is uniformly designed according to the following design parameters: electric mechanism stroke, rated torque, and maximum speed of output shaft extension or retraction; each design parameter is selected based on the maximum value among all channel's simulated electric mechanisms; by adjusting the position of the limit position switch inside each channel's simulated electric mechanism, the usage requirements of different working strokes of each channel's simulated electric mechanism are achieved.

[0029] In one implementation of this invention, such as Figure 1 As shown, the multi-channel simulated electric mechanism includes: simulated steering wheel electric mechanism, simulated steering stick electric mechanism, and simulated pedal electric mechanism.

[0030] In this implementation, the multi-channel simulation control components include: a simulation steering wheel connected to the simulation steering wheel electric mechanism via a rocker arm and a steel cable; a simulation steering stick connected to the simulation steering stick electric mechanism via a rocker arm and a lever; and a simulation pedal connected to the simulation pedal electric mechanism via a rocker arm and a lever.

[0031] In one implementation of this invention, such as Figure 1 As shown, the motor controller includes a control module and a drive module. In this implementation, the control module receives the target displacement signal sent by the host computer, processes it logically, and then sends the corresponding channel control signal to the drive module. Correspondingly, the drive module includes drive circuits for the analog electric mechanisms of each channel, and sends drive signals to the analog electric mechanisms of each channel so that the analog electric mechanisms of each channel control the extension or retraction of their respective output shafts.

[0032] In addition, the control module is also used to collect the displacement feedback values ​​of the potentiometer sensors in each channel's simulated electric mechanism and compare them with the target displacement signal. When the difference between the two is within the adjustment accuracy range, the control module determines that the adjustment is in place and stops sending control signals to the drive module.

[0033] In one implementation of this invention, such as Figure 2 As shown, the external visual display module includes: multiple visual cameras installed at various windows in the aircraft cockpit, a visual display processor connected to each visual camera, and multiple visual displays installed in the flight training experience cabin, with each visual display connected to the visual display processor.

[0034] In this implementation, the external visual display module is used to capture the view outside the pilot's window through each visual camera, process the visual video through the visual display processor, synthesize the view, and display the synthesized view to the trainees in the flight training experience cabin through each visual display.

[0035] In one implementation of this invention, such as Figure 3 As shown, the cockpit synchronized display module includes: at least one intelligent display connected to both the cockpit intelligent display and the aircraft mission management system, and a display control board connected to each intelligent display. In this implementation, the cockpit synchronized display module uses the intelligent displays to display flight status information, the status of various aircraft systems, and different mission screens.

[0036] In one specific embodiment of the present invention, two smart displays are respectively arranged on the instrument panel in front of the left and right trainees in the flight training experience cabin. By interconnecting with the smart displays in the cockpit, the displays synchronize flight operation-related screens, including: flight status information, and navigation and communication information. The flight status information includes flight speed, flight altitude, climb rate, and flight attitude. By interconnecting with the mission management system, the displays receive flight training information sent by the mission management system and display different flight training screens.

[0037] Inside the flight training cabin, trainees send interface switching signals to the smart display by operating the display control panel, thus changing the displayed screen.

[0038] This invention provides a flight control perception training system, which has the following two beneficial effects: (1) It realizes the linkage of roll, pitch and yaw three-axis control in the cockpit and flight training experience cabin, which can ensure that flight trainees can truly experience and perceive the whole process of cockpit pilots controlling the aircraft attitude by coordinating the control wheel, control stick and foot pedals, and solve the problem that flight trainees have difficulty adapting after passing the simulator training and switching to real flight. (2) Applicable to different types of trainer aircraft, it is installed in the embedded flight training experience cabin and is compatible with the left and right flight student workbench. The system does not affect the pilot's operation of the aircraft when it is normal or malfunctioning, and the overall system has high reliability.

[0039] The following is an illustrative example illustrating the implementation of the flight control perception training system provided by the present invention.

[0040] Implementation Example See Figure 1 As shown, the flight control perception training system provided in this implementation example is mainly used in large trainer aircraft. It is installed in the flight training experience cabin and interconnected with the cockpit flight control system to realize the synchronous movement of the control stick, control wheel, and pedals in the experience cabin and the cockpit. It has the function of experiencing and perceiving the cockpit pilot's control of the aircraft attitude through the control stick, control wheel, and pedals, and is used for flight trainees to experience the flight control process in advance.

[0041] The flight control awareness training system provided in this implementation example mainly consists of a drive control subsystem and an instrument display subsystem. Among them, such as... Figure 1 As shown, the drive control subsystem mainly includes: a simulated driving wheel, a simulated driving stick, simulated pedals, a motor controller, a simulated driving wheel electric mechanism, a simulated driving stick electric mechanism, a simulated pedal electric mechanism, a rocker arm, a lever, and a steel cable; the instrument display subsystem includes: an external visual display module and a cockpit synchronous display module. The cockpit synchronous display module includes: an intelligent display and a display control board, and the external visual display module includes: a visual camera, a visual display processor, and a visual display.

[0042] In the drive control subsystem, the simulated steering wheel, simulated steering stick, and simulated pedals are selected from the original cockpit control components or newly developed simulated components with the same or similar shape and weight, and the installation layout of each simulated control component is consistent with that of the cockpit control components.

[0043] The electric mechanisms for the simulated steering wheel, simulated steering stick, and simulated pedals all contain a permanent magnet brushless DC motor, a reducer assembly, a lead screw, a potentiometer sensor, a slip mechanism, and limit switches. The permanent magnet brushless DC motor provides power output; the reducer assembly connects to the brushless motor's output shaft, reducing the motor's output speed to the actual operating range and increasing the output torque; the lead screw connects to the brushless motor's output shaft, converting the rotational motion of the motor's output shaft into the linear motion of the lead screw nut and transmitting torque. The nut of the lead screw serves as the output shaft of the simulated electric mechanism, connecting to the corresponding simulated control component (the nut of the lead screw is connected to the corresponding simulated control component via a rocker arm and cable, or a rocker arm and pull rod); the potentiometer sensor is interconnected with the output shaft of the electric mechanism to collect data on the extension or retraction stroke of the electric mechanism's output shaft. The voltage signal; the limit position switch is set at the extreme position of the lead screw pair, and is used to disconnect the motor power supply when the lead screw pair moves to the extreme position. When the output shaft extends or retracts to the extreme position, the limit position switch will be pressed, thereby disconnecting the power supply of the brushless motor and stopping the electric mechanism of the corresponding channel; the slip mechanism is installed between the output shaft of the brushless motor and the lead screw pair, and is used to disengage the output shaft of the brushless motor from the lead screw pair when the load is too large. When the load torque is greater than the slip torque, the friction clutch in the slip mechanism will disengage, thereby disconnecting the connection between the brushless motor and the output shaft of the mechanism, and avoiding damage to the internal motor due to excessive load.

[0044] Each channel's simulated electric mechanism can be designed according to the following specifications: 1) electric mechanism stroke; 2) rated torque; 3) maximum speed of output shaft extension or retraction. Different working strokes of the electric mechanism can be achieved by adjusting the limit position switches.

[0045] The motor controller adopts a control module + drive module architecture. The control module receives the automatic adjustment target displacement signal from the host computer (the displacement signal of each control component is the displacement signal of the corresponding control component in the cockpit). After logical processing by the control module, it sends the corresponding channel control signal to the drive module (each channel control signal includes four signals: enable signal, direction, speed, and clutch control). The drive module includes the drive circuits corresponding to the analog electric mechanisms of each channel. The analog electric mechanisms of each channel receive the control signals sent by the drive module and control the extension or retraction of the output shaft. In addition, the control module collects the displacement feedback value of the potentiometer sensor in the analog electric mechanism and compares it with the automatic adjustment target displacement signal. When the difference between the two is within the adjustment accuracy range, the control module determines that the adjustment is in place and stops sending control signals to the drive module.

[0046] See Figure 1As shown, the motor controller communicates with the host computer, receiving displacement signals from the control wheel, control stick, and pedals in the cockpit, processing them, and sending the processed speed control command signals to the simulated control wheel electric mechanism, simulated control stick electric mechanism, and simulated pedal electric mechanism. The output shaft of the simulated control wheel electric mechanism is connected to the simulated control wheel via a rocker arm and steel cable. Based on the received command signals, it controls the extension or retraction of the output shaft, driving the rocker arm to rotate. The rotation of the rocker arm drives the steel cable along a pulley, causing the simulated control wheel to move synchronously with the control wheel in the cockpit. Similarly, the output shafts of the simulated control stick electric mechanism and the simulated pedal electric mechanism are connected to the simulated control stick and simulated pedals via rocker arms and levers, respectively. Based on the received command signals, they control the extension or retraction of the output shaft, driving the rocker arm to rotate. The rocker arm movement is transmitted to the simulated control stick and simulated pedals via the levers, thereby driving the simulated control stick and simulated pedals to move synchronously with the corresponding control components in the cockpit. When the difference between the displacement feedback value of each channel's simulated electric mechanism and the automatic adjustment target displacement value is within the adjustment accuracy range, the motor controller stops sending speed adjustment command signals to each channel's simulated electric mechanism, the simulated electric mechanism of each channel stops working, and each simulated control component stops at its current position, thereby realizing closed-loop control of the motor controller over the movement of each simulated control component.

[0047] The visual cameras are used to capture the view outside the windows. There are four visual cameras in total, one each at the left and right driver's main viewing windows and side windows, used to capture the view outside the left and right driver's windows.

[0048] See Figure 2 As shown, the visual display processor is used for processing and compositing visual video. Each visual camera is interconnected with the visual display processor, sending visual video signals to it. After receiving the visual video signals, the visual display processor processes them, composites the corresponding visuals, and outputs them.

[0049] See Figure 2 As shown, the visual display is used to display the synthesized visual scene. Four visual displays are arranged in the flight training cabin for the flight trainees. Two visual displays are located on the instrument panel in front of the left and right flight trainees, respectively, and two visual displays are located on both sides of the instrument panel. All four visual displays are interconnected with the visual display processor to receive the visual video signals sent by the visual display processor and display the view outside the windows of the left and right pilots in the cockpit.

[0050] See Figure 3As shown, the intelligent displays are used to display flight status information, the status of various systems in the aircraft, and different mission screens. Two intelligent displays are respectively installed on the instrument panels in front of the left and right trainees in the flight training cabin. These displays are interconnected with the intelligent displays in the cockpit, synchronizing flight control-related screens, including flight status information such as flight speed, altitude, climb rate, and attitude, as well as navigation and communication information; they are also interconnected with the mission management system, receiving flight training information from the system and displaying different flight training screens. A display control panel is located below each intelligent display and is interconnected with the display, sending interface switching signals to it. Each display control panel controls one intelligent display, switching the display screen accordingly.

[0051] The working principle of the flight control awareness training system provided in this implementation example: See [link / description] Figures 1 to 3 As shown, during flight, the left and right pilots in the cockpit control the aircraft's attitude by manipulating the control wheel, stick, and pedals. The host computer collects the motion displacement or angle information of each control component and sends it to the motor controller for calculation and logical processing. The motor controller outputs corresponding control signals, and the simulated electric mechanisms in each channel receive the control signals and control the extension or retraction of the output shaft. These movements are then controlled synchronously by transmission components such as rocker arms, levers, and cables. By interacting with the simulated control components, flight trainees can realistically experience and perceive the entire process of cockpit pilots controlling the aircraft's attitude by manipulating the control wheel, stick, and pedals. The intelligent display on the instrument panel synchronously displays the flight data screen from the cockpit's intelligent display. By observing the flight data, flight trainees can obtain information about the aircraft's attitude and the status of each system. They can switch screens via the display control panel to display different system status information and flight training scenarios. A visual camera captures the scene outside the cockpit pilot's window in real time, which is displayed in real time on the visual display on the instrument panel, realistically reproducing the pilot's perspective from inside the cockpit.

[0052] In special circumstances, when the system loses power, the simulated control wheel, control stick, and pedals in the flight training cabin remain in their pre-power-loss positions. When the system is powered on, if the displacement information of each simulated control component is inconsistent with that of the control components in the cockpit, the simulated electric mechanisms will uniformly and slowly drive each simulated control component to match the displacement of the control components in the cockpit within 3 seconds before responding synchronously. When the flight student's gripping force on the simulated control components exceeds 180N, the simulated electric mechanisms in each channel will slip. When the gripping force decreases to 180N, the simulated electric mechanisms will uniformly and slowly drive each simulated control component to match the displacement of the control components in the cockpit before responding synchronously.

[0053] While the embodiments disclosed in this invention are as described above, they are merely illustrative of the embodiments to facilitate understanding of the invention and are not intended to limit the invention. Any person skilled in the art to which this invention pertains may make any modifications and variations in the form and details of the implementation without departing from the spirit and scope disclosed herein; however, the scope of patent protection for this invention shall still be determined by the scope defined in the appended claims.
