Description

Technical Field

[0001] The present invention relates to the technical field of scaled model testing of an out-of-water navigation body, and in particular to a compressed gas power simulation device and method for accelerating the acceleration of combustion gas in a navigation body cylinder. Background Art

[0002] During the underwater emergence process, the high-temperature and high-pressure gas generated by the gas generator pushes the vehicle in the launch tube to obtain the initial speed, and then relies on its own inertia and buoyancy to cross the water layer and emerge from the water. In the short process from the beginning of the movement of the underwater vehicle in the launch tube to the moment when its tail touches the water surface and completes the emergence from the water, the vehicle will experience various complex environmental changes, and its motion state may be affected by multiple factors such as high-temperature gas, underwater environment, and launch device. Among them, gas power has an important influence on the running speed, load, motion posture, etc. of the vehicle during its movement, and is one of the important research contents of underwater launch technology for vehicles. Therefore, setting up a safe and reliable compressed gas power device is crucial to ensure the successful and effective emergence of the vehicle from the water.

[0003] Due to the limitations of environmental and economic factors, it is difficult to carry out full-scale tests. Full-scale tests often require obtaining a large number of samples through model experiments. However, it is not convenient to use high-temperature and high-pressure gases to propel the navigation body out of the water in model tests, and the test results are inaccurate as the gas content gradually decreases. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art of inaccurate test results caused by the gradual decrease in the content of fuel gas, thereby providing a compressed gas power simulation device and method for fuel gas-driven acceleration in the cylinder of a navigation body.

[0005] In order to solve the above technical problems, the present invention provides a compressed gas power simulation device for accelerating a navigation body in a cylinder by fuel gas, comprising: an air compressor and a high-pressure gas tank, a barometer, a heating wire, a ventilator, an air bag box, a launching tube, a low-pressure air chamber, a navigation body, and a control cabinet; the high-pressure gas tank is connected to the air compressor, the high-pressure gas tank is provided with a barometer, the heating wire is arranged on the inner wall of the high-pressure gas tank, the air bag box is arranged in the high-pressure gas tank, the air bag box is provided with an air bag, the ventilator is connected to the air bag box, the high-pressure gas tank is connected to the launching tube, the low-pressure air chamber and the navigation body are arranged in the launching tube, and the control cabinet is connected to the air compressor and the barometer, the heating wire, and the ventilator.

[0006] Furthermore, a first air intake pipe is provided between the high-pressure air storage tank and the air compressor, and a first air intake valve is provided on the first air intake pipe.

[0007] Furthermore, the high-pressure gas storage tank is provided with a first air inlet, and the first air inlet pipe is connected to the first air inlet.

[0008] Furthermore, a ventilation pipe is provided between the airbag box and the ventilator, and a second air inlet valve is provided on the ventilation pipe.

[0009] Furthermore, the high-pressure gas storage tank is provided with a second air inlet, and the ventilation pipe is connected to the airbag box through the second air inlet.

[0010] Furthermore, a second air intake pipe is provided between the high-pressure air storage tank and the launching tube, and an inlet valve is provided on the second air intake pipe.

[0011] Furthermore, the high-pressure gas storage tank is provided with an air outlet, the launching tube is provided with a third air inlet, and the second air inlet pipe connects the air outlet and the third air inlet.

[0012] Furthermore, it also includes a navigation body bracket, and the navigation body bracket is provided between the low-pressure air chamber and the navigation body.

[0013] Furthermore, a sealing coating is provided on the inner wall of the airbag.

[0014] The present invention also provides a working method of a compressed gas power simulation device that uses the gas in the cylinder of a navigation body to propel acceleration, comprising:

[0015] Arrange and install all parts in order, then load the vehicle model into the launch tube and complete various performance checks before the test;

[0016] The air compressor is started through the control cabinet to start working, the first air inlet valve is opened, the air is compressed into high-pressure gas and stored in the high-pressure gas storage tank, the pressure value of the barometer is observed, the pressure in the high-pressure gas storage tank reaches the preset pressure value, a high-pressure chamber is formed, the heating wire is started to heat the gas in the high-pressure gas storage tank, and high-temperature and high-pressure gas is formed, then the air compressor and the first air inlet valve are closed, after receiving the instruction of the vehicle to exit the tube, the ventilator is started through the control cabinet, gas is injected into the airbag, the airbag begins to expand, and is pushed out of the airbag box, gradually expanding and discharging the high-temperature and high-pressure gas in the high-pressure gas storage tank, further compressing the high-temperature and high-pressure gas in the high-pressure gas storage tank to increase the pressure, and at the same time, the inlet valve is opened to release the high-temperature and high-pressure gas from the high-pressure gas storage tank and quickly enter the low-pressure air chamber at the bottom of the launch tube. When the pressure in the low-pressure air chamber at the bottom reaches the preset pressure value of the exit tube, the vehicle bracket carries the vehicle and moves upward along the launch tube under the push of the high-pressure gas, and the vehicle bracket then falls off; after the vehicle successfully exits the tube, the ventilator and each valve are closed in turn.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. The compressed gas power simulation device for accelerating a navigation body in a cylinder propelled by gas provided by the present invention comprises: an air compressor and a high-pressure gas tank, a barometer, a heating wire, a ventilator, an air bag box, a launching tube, a low-pressure air chamber, a navigation body, and a control cabinet; the high-pressure gas tank is connected to the air compressor, the high-pressure gas tank is provided with a barometer, the heating wire is arranged on the inner wall of the high-pressure gas tank, the air bag box is arranged in the high-pressure gas tank, the air bag box is provided with an air bag, the ventilator is connected to the air bag box, the high-pressure gas tank is connected to the launching tube, the low-pressure air chamber and the navigation body are arranged in the launching tube, and the control cabinet is connected to the air compressor, the barometer, the heating wire, and the ventilator.

[0019] The high-pressure gas storage tank is connected to the air compressor, so that the high-pressure gas compressed by the air compressor can be transported to the high-pressure gas storage tank, and a stable and closed high-pressure area is formed in the high-pressure gas storage tank, and the pressure value in the high-pressure gas storage tank is detected in real time by using a barometer. Then, the high-pressure gas in the high-pressure gas storage tank is heated by using the heating wire in the tank wall interlayer of the inner wall of the high-pressure gas storage tank, so that the high-pressure gas is converted into high-temperature and high-pressure gas, thereby simulating the high-temperature and high-pressure gas generated when the navigation body is pushed out of the tube. The airbag box is arranged on one side of the high-pressure gas storage tank, which is used to store the airbag that is contracted in the uninflated state. A free switch is set on one side of the airbag box to ensure that the airbag can be broken and pushed out after expansion; the airbag is used to push the high-temperature and high-pressure gas in the high-pressure gas storage tank after inflation; when the experiment is needed, the high-temperature and high-pressure gas in the high-pressure gas storage tank is transported to the launch tube, first enters the low-pressure air chamber, and then uses the high-temperature and high-pressure gas to push the navigation body, so that the navigation body obtains continuous driving force, ensuring the accuracy of the test results.

[0020] The compressed gas power simulation device for accelerating the vehicle in the cylinder by gas propulsion uses high-pressure compressed gas power to propel the vehicle upward. Compressed gas propulsion uses compressed air at room temperature as the gas medium. No high-temperature toxic or harmful gas is generated during the process of the vehicle exiting the cylinder. The entire propulsion system has low economic cost, no pollution, high safety, and fully utilizes energy. It can be adjusted, and the pressure changes smoothly. Ideal in-cylinder motion parameters can be obtained. Compared with conventional thermal launch methods, it will not cause damage such as ablation to the vehicle and the device equipment, and can be tested repeatedly. Its principle is relatively simple, which is convenient for conducting large sample tests to obtain data for related mechanism research.

[0021] At the same time, the airbag design for propelling compressed gas is a flexible medium object. The most prominent and obvious flexible propulsion performance is the airbag's deployment effect. The flexible wall of the airbag can be folded and can withstand a certain pressure. The shape of the airbag will change as the gas is filled. An airbag box and an airbag are added to the original high-pressure gas storage tank. By injecting gas into the airbag, the airbag is released and expanded from the airbag box. The volume of the airbag gradually increases, and the compressed high-temperature and high-pressure gas outside the airbag is further pressurized, gradually pushed out and pushed to the bottom of the launch tube. A large amount of high-pressure gas accumulates at the bottom to provide a driving force for the vehicle to accelerate out of the tube. The airbag is used to simulate the process of a real gas generator, thereby further simulating the acceleration time history curve process and the force process of the vehicle when the vehicle accelerates out of the tube.

[0022] Different from the traditional process of accelerating the vehicle out of the tube using a fixed-volume gas cylinder as the pressure source, the gas pressure injected into the bottom of the tube by the gas cylinder gradually decreases as the gas is discharged. However, the actual gas-driven power gas injection is a constant-pressure injection, or even a supercharged injection process. The airbag propulsion method can achieve a constant or supercharged gas injection process, more accurately simulate the pressure conditions at the bottom of the tube when the gas drives the vehicle out of the tube, and achieve the ability to adjust more model acceleration motion dynamic parameters by changing the temperature, airbag propulsion process, etc.

[0023] In addition, the thermodynamic process of an actual vehicle accelerating out of the cylinder can be simulated. A heatable heating wire is arranged in the interlayer of the tank wall of the high-pressure gas storage tank, which can further heat the high-pressure gas and simulate the thermodynamic change process under the real prototype, so as to better simulate the real process of the actual gas pushing the vehicle to accelerate out of the cylinder.

[0024] 2. The compressed gas power simulation device for accelerating the navigation body in the cylinder of the vehicle provided by the present invention has a sealing coating on the inner wall of the airbag to ensure the sealing of the gas.

[0039] See also Figures 1 to 4 As shown, the present invention provides a compressed gas propulsion simulation device for accelerating a water-borne vehicle 15 out of a tube, comprising: an air compressor 1 and a high-pressure gas tank 4, a barometer 5, a heating wire 21, a ventilator 6, an airbag box 9, a launching tube 13, a low-pressure air chamber 16, a vehicle 15, and a control cabinet 22; the high-pressure gas tank 4 is connected to the air compressor 1, the high-pressure gas tank 4 is provided with a barometer 5, the heating wire 21 is arranged on the inner wall of the high-pressure gas tank 4, the airbag box 9 is arranged in the high-pressure gas tank 4, the airbag 10 is arranged in the airbag box 9, the ventilator 6 is connected to the airbag box 9, the high-pressure gas tank 4 is connected to the launching tube 13, the low-pressure air chamber 16 and the vehicle 15 are arranged in the launching tube 13, and the control cabinet 22 is connected to the air compressor 1 and the barometer 5, the heating wire 21, and the ventilator 6.

[0040] The high-pressure gas storage tank 4 is connected to the air compressor 1, so that the high-pressure gas compressed by the air compressor 1 can be transported to the high-pressure gas storage tank 4, and a stable and closed high-pressure area is formed in the high-pressure gas storage tank 4. The pressure value in the high-pressure gas storage tank 4 is detected in real time by the barometer 5. The high-pressure gas in the high-pressure gas storage tank 4 is heated by the heating wire 21 in the tank wall interlayer of the inner wall of the high-pressure gas storage tank 4, so that the high-pressure gas is converted into high-temperature and high-pressure gas, thereby simulating the high-temperature and high-pressure gas required when the navigation body is out of the cylinder. The airbag box 9 is arranged on one side of the high-pressure gas tank 4, and is used to store the deflated airbag 10 in the uninflated state. A free switch is set on one side of the airbag box 9 to ensure that the airbag 10 can be broken and released after expansion; the airbag 10 is used to propel the high-temperature and high-pressure gas in the high-pressure gas tank 4 after inflation; when experiments are needed, the high-temperature and high-pressure gas in the high-pressure gas tank 4 is transported to the launching tube 13, first enters the low-pressure air chamber 16, and then uses the high-temperature and high-pressure gas to push the navigation body 15, so that the navigation body 15 obtains continuous propulsion force, thereby ensuring the accuracy of the test results.

[0041] The compressed gas propulsion simulation device for accelerating the out-of-water vehicle 15 out of the tube uses high-pressure compressed gas to propel the vehicle upward. The compressed gas uses compressed air at room temperature as the gas medium, and no high-temperature toxic and harmful gas is generated during the process of the vehicle exiting the tube. The economic cost of the entire system is low, pollution-free, and safe. The energy can be fully utilized and can be adjusted. The pressure changes smoothly, and the ideal acceleration motion parameters in the tube can be obtained. Compared with the conventional thermal launch method, it will not cause damage such as ablation to the vehicle and the device equipment, and can be repeated. The principle is relatively simple, which is convenient for conducting large sample experiments to obtain data for related mechanism research.

[0042] At the same time, the design of the airbag 10 for propelling compressed gas is that the airbag 10 is a flexible medium object. The most prominent and obvious flexible propulsion performance is the unfolding effect of the airbag 10. The flexible wall of the airbag 10 can be folded and can withstand a certain pressure. The shape of the airbag 10 will change with the filling of gas. The airbag box 9 and the airbag 10 are added to the original high-pressure gas storage tank 4. By injecting gas into the airbag 10, the airbag 10 is released and expanded from the airbag box 9. The volume of the airbag 10 gradually increases, and the compressed high-temperature and high-pressure gas outside the airbag 10 is further pressurized, gradually pushed out and pushed to the bottom of the launch tube 13. A large amount of high-pressure gas is accumulated in the low-pressure air chamber 16, providing a driving force for the vehicle 15 to accelerate out of the tube. The airbag 10 is used to simulate the process of a real gas generator, thereby further simulating the acceleration time history curve process and force process of the vehicle 15 when the vehicle accelerates out of the tube.

[0043] Different from the process of the vehicle 15 coming out of the tube using a traditional fixed-volume gas cylinder as the pressure source, the gas pressure injected into the bottom of the tube by the gas cylinder gradually decreases as the gas is discharged. However, the actual gas-driven power gas injection is a constant-pressure injection, or even a pressurized injection process. The airbag 10 propulsion method can achieve a constant or pressurized gas injection process, more accurately simulate the pressure conditions at the bottom of the tube when the gas-driven vehicle comes out of the tube, and achieve the ability to adjust more model acceleration motion dynamic parameters by changing the temperature, the airbag 10 propulsion process, etc.

[0044] Furthermore, the thermodynamic process of an actual vehicle accelerating out of the cylinder can be simulated. The heatable heating wire 21 is arranged in the tank wall interlayer of the high-pressure gas storage tank 4, which can further heat the high-pressure gas and simulate the thermodynamic change process under the real prototype, so as to better simulate the real process of an actual vehicle exiting the cylinder.

The second air inlet pipe 12 connects the air outlet 20 and the third air inlet 19, thereby realizing the connection between the high-pressure gas storage tank 4 and the launch tube 13.

[0049] In some optional embodiments, the compressed gas propulsion simulation device for accelerating the out-of-water vehicle 15 out of the cylinder further includes a vehicle bracket 14, and the vehicle bracket 14 is provided between the low-pressure air chamber 16 and the vehicle 15. The vehicle bracket 14 is used to carry the vehicle 15, and usually the high-temperature and high-pressure gas pushes the vehicle bracket 14, and the vehicle bracket 14 pushes the vehicle 15 to move upward, and then falls off.

[0050] In some optional embodiments, the airbag 10 is made of polyamide fabric with good anti-cracking performance and can withstand greater pressure; the inertial force of the airbag 10 when inflated can be reduced. At the same time, a sealing coating is provided on the inner wall of the airbag 10 to ensure the sealing of the gas.

[0051] The installation process of the compressed gas propulsion simulation device for accelerating the out-of-water navigation body 15 is as follows: first, the launch tube 13 is arranged in the working area and fixed to ensure its stability; then the air compressor 1 is connected to the high-pressure gas storage tank 4 with the first air inlet pipe 2, the ventilator 6 is connected to the high-pressure gas storage tank 4 with the second air inlet pipe 12, and the control cabinet 22 is connected to the air compressor 1 and the ventilator 6 with the signal transmission cable 23. After the connection is completed, check the sealing of the device and whether the air valves on each air pipe can be used normally; finally, the high-pressure gas storage tank 4 is connected to the third air inlet 19 at the bottom of the launch tube 13 with the second air inlet pipe 12 to ensure the smoothness of the entire pipeline. All interfaces are reinforced to ensure their sealing.

The high-pressure gas in the high-pressure gas tank 4 is released, and the high-temperature and high-pressure gas in the high-pressure gas tank 4 is further compressed to increase the pressure. At the same time, the inlet valve 11 is opened to release the high-temperature and high-pressure gas from the high-pressure gas tank 4 and quickly enter the low-pressure air chamber 16 at the bottom of the launch tube 13. When the pressure in the low-pressure air chamber 16 at the bottom reaches the preset pressure value required for the accelerated movement of the vehicle, the vehicle bracket 14 carries the vehicle 15 and moves upward along the launch tube 13 under the push of the high-pressure gas, and the vehicle bracket 14 then falls off. After the vehicle 15 successfully exits the tube, the ventilator 6 and each valve are closed in turn.
