Description

Technical Field

[0001] This utility model relates to the field of air cannon technology, specifically a dual-cylinder high-speed self-locking air cannon. Background Technology

[0002] Ejection escape is a crucial means of emergency ejection and life protection in situations where an aircraft experiences irreversible malfunction or the pilot is unable to control the aircraft to return to the airport. With the development of aviation technology, the performance of ejection escape equipment is constantly improving; however, pilot ejection is not 100% successful. According to in-depth analysis by industry experts, the three main factors affecting safe ejection escape are: equipment factors, human factors, and aircraft attitude factors.

[0003] Existing air cannon equipment has certain shortcomings in use:

[0004] 1. The main reasons affecting the success of ejection are improper timing of ejection, non-standard ejection and ejection preparation actions, and unclear mastery of the relevant theoretical knowledge of ejection and parachuting. Improper timing of ejection includes two types: hesitation before ejection and accidental ejection when it should not be ejected. Hesitation before ejection is also known as delayed ejection decision.

[0005] 2. To avoid errors and omissions in ejection escape maneuvers; to improve pilots' ability to judge emergencies and prevent misjudgments; and to strengthen simulated ejection escape drills, which are of great significance for some pilots with relatively weak technical foundations. Utility Model Content

[0006] The purpose of this utility model is to provide a dual-cylinder high-speed self-locking air cannon to address the issues raised in the background art, such as pilots' improper timing of ejection, non-standard ejection and preparation actions, and unclear understanding of ejection parachute-related theoretical knowledge, which are the main reasons affecting the success of ejection rescue. Improper timing of ejection includes two types: hesitation before ejection and accidental ejection when it should not be done. Hesitation before ejection is also known as delayed ejection decision. This invention aims to avoid errors and omissions in ejection rescue actions, improve pilots' judgment ability in the face of emergencies, and prevent misjudgment. In view of the fact that some pilots have relatively weak technical foundations, strengthening the simulation exercise of ejection rescue is of great significance.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0010] As a preferred embodiment of this utility model, a pressure-reducing pad is provided on the side of the pressure-reducing plate of the pneumatic cylinder, and the pressure-reducing pad and the pressure-reducing plate of the pneumatic cylinder are connected by a limit screw thread.

[0011] As a preferred embodiment of this utility model, a cylinder piston rod locking member is provided on the outer surface of the cylinder piston rod, and the cylinder piston rod locking member is located on the side of the cylinder piston.

[0012] As a preferred embodiment of this utility model, the other end of the cylinder body is threadedly connected to a lower cylinder cover, and the lower cylinder cover and the upper cylinder cover are positioned opposite each other.

[0013] As a preferred embodiment of this utility model, a pin is provided on the side of the lower end cover of the cylinder. The pin passes through the lower end cover of the cylinder and extends into the cylinder piston rod locking member. The pin is inserted into the lower end cover of the cylinder, and a lower end seal is provided at the connection between the pin and the lower end cover of the cylinder.

[0014] As a preferred embodiment of this utility model, an air inlet and a sensor are respectively provided on the side of the lower end cover of the cylinder, and a pull rod is fixedly connected to the side of the lower end cover of the cylinder. The pull rod passes through the upper end cover of the cylinder and is slidably connected to the upper end cover of the cylinder.

[0015] As a preferred embodiment of this utility model, the outer surface of the pull rod is threaded with a fixing nut, which is located on the side of the upper end cover of the cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, by setting up a return cylinder body, a return cylinder piston, a return cylinder sealing gasket, and a cylinder piston rod locking component, the power of the ejection seat comes from the rapid ejection of the cabin along the ejection track. Among them, the dual-cylinder high-speed self-locking air cannon, with its powerful thrust, rapid speed, and excellent safety, is particularly suitable for ejection simulators. The high-speed dual-cylinder self-locking mechanism is designed specifically for ejection simulators. It not only has a fast ejection speed, but also performs well in terms of performance and safety. Based on the above characteristics, we can conclude that using the high-speed dual-cylinder self-locking mechanism as the ejection power source in the ejection simulator will provide a safer and more reliable experience.

[0018] 2. In this utility model, by using a combination of a pneumatic cylinder pressure-reducing plate, a pneumatic cylinder pressure-reducing rod spring, a pressure-reducing spring, and a pull rod, a spring rod with a pressure-reducing spring is specially designed between the pressure-reducing plate and the cylinder piston. This configuration allows the pressure-reducing spring to play a buffering role during operation, thereby effectively extending the service life of the cylinder piston rod. Furthermore, connecting the upper and lower end covers of the cylinder with the pull rod further enhances the stability of the overall structure. Attached Figure Description

[0026] Among them, the cylinder body 13, the upper cylinder cover 15, the lower cylinder cover 12, and the cylinder piston rod 5 are made of high-strength steel and are heat-treated to increase their strength.

[0027] According to this embodiment Figure 1 , Figure 2 and Figure 3 As shown, a pneumatic cylinder depressurization plate 7 is provided on the outer surface of the cylinder piston rod 5. A cylinder piston 6 is provided on the side of the cylinder piston rod 5. A pneumatic cylinder depressurization plate spring rod 9 is provided between the cylinder piston 6 and the pneumatic cylinder depressurization plate 7. A depressurization spring 10 is sleeved on the outer surface of the pneumatic cylinder depressurization plate spring rod 9. A pneumatic cylinder depressurization pad 8 is provided on the side of the pneumatic cylinder depressurization plate 7. The pneumatic cylinder depressurization pad 8 and the pneumatic cylinder depressurization plate 7 are connected by a limit screw threaded connection. A cylinder piston rod locking member 11 is provided on the outer surface of the cylinder piston rod 5. The cylinder piston rod locking member 11 is located on the side of the cylinder piston 6. The other end of the cylinder body 13 is threadedly connected to a lower cylinder end cover 12. The end cap 12 and the upper end cap 15 of the cylinder are positioned opposite each other. A pin 17 is provided on the side of the lower end cap 12 of the cylinder. The pin 17 passes through the lower end cap 12 of the cylinder and extends into the cylinder piston rod locking member 11. The pin 17 is inserted into the lower end cap 12 of the cylinder. A lower end seal 18 is provided at the connection between the pin 17 and the lower end cap 12 of the cylinder. An air inlet and a sensor are respectively provided on the side of the lower end cap 12 of the cylinder. A pull rod 16 is fixedly connected to the side of the lower end cap 12 of the cylinder.

[0029] The working process of this utility model is as follows: When the dual-cylinder high-speed self-locking air cannon designed using this scheme is in operation, first check whether the device is working properly. The operator connects the air compressor to the device through a solenoid valve. When the sensor passes through, it transmits the data to the host computer and controls the opening or closing of the device. Since the side of the cylinder piston rod 5 is respectively equipped with the return cylinder piston 3 and the cylinder piston 6, a secondary cylinder is designed. The secondary cylinder can open the exhaust port of the primary cylinder, reduce the exhaust resistance of the primary gas, and increase the projectile speed.
