specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1-Figure 7 Illustrate, a kind of rotatable light gas cannon device of the present embodiment comprises air chamber 1; It also comprises launch tube 2, bomb support separation device 5, support platform 6, two-way hydraulic oil cylinder 7, base support 13, angle sensor 10 and two speedometers 4;

[0016] The air chamber 1, the launch tube 2 and the support platform 6 are located above the base bracket 13, the launch tube 2 is arranged horizontally, and the air chamber 1 and the launch tube 2 are all fixedly mounted on the upper surface of the support platform 6. The bullet holder separation device 5 Including the sleeve barrel 5-2 and the tapered barrel 5-1 made into one, the large-diameter end face of the tapered barrel 5-1 is connected with the bottom end surface inside the barrel 5-2, the middle part of the tapered barrel 5-1 is connected with the sleeve The bottom of the barrel 5-2 is processed with a coaxial through...

specific Embodiment approach 2

[0020] Specific implementation mode two: combination Figure 5 Note that the cone angle of the conical cylinder 5-1 of this embodiment is 45°. Such arrangement can satisfy the launch of the projectile body with the bullet rest and the separation of the bullet rest and the projectile body. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific implementation mode three: combination Figure 5 To illustrate, the velocimeter 4 in this embodiment is a laser velocimeter. In this way, the laser speedometer is a non-contact precision instrument for measuring the speed and length of the object, with high precision and low energy consumption. There is a certain distance between the two laser speedometers when in use. The laser transmitter and laser receiver of the laser speedometer are installed On the side wall of the launch tube, the laser emitter and laser receiver on each laser velocimeter are arranged facing each other, and the velocity of the projectile passing through is measured by two parallel laser beams. Others are the same as in the first or second embodiment.

Abstract

A rotatable light-gas gun device relates to a light-gas gun and aims at solving the problems of an existing screw rod type rotatable light-gas gun that the utilization is inconvenient, the rotary speed is slower, the working efficiency is lower and the adaptability is poor. The rotatable light-gas gun device comprises a gas chamber, and further comprises an emission tube, a sabot separation device, a supporting platform, a bidirectional hydraulic oil cylinder, a base bracket, an angle transducer and two tachometers, wherein the gas chamber, the emission pipe and the supporting platform are located above the base bracket; the gas chamber and the emission pipe are fixedly arranged on the upper surface of the supporting platform; the sabot separation device comprises a sleeve bucket and a tapered cylinder which are integrally molded; one end of the emission pipe and the gas chamber are communicated and are detachably connected; the other end of the emission pipe is connected with the sleeve bucket; the tapered cylinder is arranged in the emission pipe; the angle transducer is mounted on the base bracket; one end of the bidirectional hydraulic oil cylinder is rotationally connected with one end of the supporting platform, and the other end of the bidirectional hydraulic oil cylinder is rotationally connected with the base bracket. The rotatable light-gas gun device is used for the fields including space vehicles or material performance researches and the like.

Description

technical field [0001] The invention relates to a light gas cannon, in particular to a light gas cannon device capable of rotating and launching in a vertical plane. Background technique [0002] The light gas gun device can launch projectiles of different shapes and materials to meet the needs of various high-speed and ultra-high-speed experiments. It is currently used in the research of kinetic energy weapon effects, geospace physics research, spacecraft protection research, and material performance research under high strain rates. Widely used, it is the most common high-speed and ultra-high-speed drive equipment. Compared with ordinary light gas cannon devices, the rotatable light gas cannon device has the characteristics of being able to launch projectiles at different angles and realize hitting targets at different angles. [0003] At present, there are very few light gas guns with rotation angles both at home and abroad. NASA (NASA) Ames Research Center has a set of...
