Pneumatic catapulting device and method of reusable working medium

Abstract

The invention discloses a catapulting device and method of a reusable working medium. The device comprises a carrying barrel, electromagnetic roll boosters, a buffering sealing piece, a stroke sensor,a catapulting cavity wall, a carrying barrel pull rod, communication holes, pull rod plugs, a servo motor a, a pull rod frame, a servo motor b, a compensatory pressure sensing switch, a pressure compensation hole, a gas storage cavity wall, a working medium compensation cavity wall, a supercharging hole, a working medium gas generator and a small supercharger. The potential energy of high-pressure working medium gas is converted into kinetic energy to promote the carrying barrel to move, so that the catapulting action of a to-be-catapulted carrier is achieved, in combination with the electromagnetic roll boosters, the electromagnetic roll boosters are started at the moment when the to-be-catapulted carrier is separated from a contact face of the carrying barrel, and the to-be-catapulted carrier is secondarily accelerated. The working medium gas is reused, the to-be-catapulted carrier is secondarily accelerated through the arranged electromagnetic roll boosters, the number of times offrequent replacement of an externally-connected gas bottle is reduced, the time cost of the launching process is reduced, and the use efficiency of a launching system is greatly improved.

Description

technical field [0001] The invention relates to a projecting device which utilizes double servo motors to improve the energy utilization rate of the working medium, and is especially suitable for use occasions where the working medium is inconvenient to be replenished and replaced and needs to be reused, and belongs to the technical field of function optimization and enhancement of the projecting system. Background technique [0002] In recent years, there have been more and more activities on lunar exploration projects and deep space exploration at home and abroad, and the demand for launching a large number of small unpowered probes has also increased. Such demands have greatly promoted the development process of low-efficiency and high-efficiency projectiles in space. As an effective means of achieving a certain speed for launching detectors and micro-nano satellites, kinetic energy projectiles using gas working fluids can meet this demand background. developed rapidly. ...

Problems solved by technology

[0006] 1. The compressed spring energy storage type projectile not only cannot achieve the projectile ability of large kinetic energy, but due to the limitation of the mechanism, if it wants to achieve a certain projectile ability, it will cause problems of its own structure and excessive volume, which cannot be realized in some specific occasions. Applications

[0007] The pressure resistance of the external gas storage equipment is too high, and the gas chamber of the traditional light gas gun has no self-increasing mechanism. Therefore, the external gas storage equipment must meet the ultra-high pressure to ensure the continuous inflation of the gas chamber and complete the ultra-high pressure of the projectile. High-speed launch, therefore, the pressure resistance requirements for external gas storage equipment are extremely strict, which greatly increases the hidden danger of system safety

[0008] 2. Consumable working fluid type projectiles will consume a certain amount of working fluid after each projectile, and with the consumption of working fluid, its projecting ability will become weaker and weaker, especially if it cannot meet certain requirements. Applications where it is difficult to supplement and replace the working medium seriously restrict the use efficiency and its application range

[0009] 3. Consumption of working fluid type ejector, in order to achieve multiple projections, it needs to be equipped with high-pressure, high-quality working fluid storage equipment and pressure modulation equipment, which seriously increases the quality of the entire projectile system and significantly increases the cost of transportation and use , increasing the safety hazards of equipment operation
