Novel two-stage light-gas gun driven by high pressure air

Abstract

The invention provides a novel two-stage light-gas gun driven by high pressure air and belongs to the technical field of light-gas gun experiments. The novel two-stage light-gas gun mainly comprises asupport, a first-stage air chamber, a first-stage air chamber electromagnetic valve, a trigger electromagnetic ball valve, a second-stage air chamber, a large piston, a small piston, a launching pipe, an air release device and the like. A two-stage air chamber power source is adopted, the second-stage air chamber is divided into a large piston section and a small piston section, the two inside pistons are in rigid linkage, in the initial state, the first-stage air chamber and the small piston section of the second-stage air chamber are filled with high pressure air, storage and release of thehigh pressure air are controlled by the electromagnetic valve, and thus under the circumstance that initiating explosive devices, hydrogen and other flammable and explosive gases cannot be provided,superspeed flying of an object is achieved through air compression loading. The novel two-stage light-gas gun is safe and reliable, superspeed flying of the object is achieved with a compressed air method, experiment cost is low, and operation is safe, simple and convenient.

Description

technical field [0001] The invention relates to a novel two-stage light gas cannon driven by high-pressure air, which belongs to the technical field of light gas cannon experiments. Background technique [0002] Light gas cannon loading technology is the most commonly used means and method for studying the collision of ultra-high-speed objects in contemporary times, and there are many kinds of light gas cannons, among which there are more secondary and tertiary light gas cannons. The commonly used secondary light gas gun is composed of two high-pressure gas chambers with different inner diameters. Generally, the primary gas chamber is filled with inert gas or driven by gunpowder to compress the piston, and the secondary gas chamber is filled with hydrogen and other light gases. The piston in the primary gas chamber compresses the hydrogen gas in the secondary gas chamber, so that the hydrogen gas can be ignited to produce a large amount of gas in a limited volume. The huge p...

Problems solved by technology

[0004] The object of the present invention is to provide a novel two-stage light gas gun driven by high-pressure air, using a two-stage air chamber power source, wherein the two-stage air chamber is divided into a large piston section and a small piston section, and the two pistons are rigidly linked. State The small piston section of the primary air chamber and the secondary air chamber is filled with high-pressure air, and the storage and release of high-pressure air is controlled by a solenoid valve to solve the problem of using inflammable and explosive gases such as pyrotechnics and hydrogen. Air compression loading realizes ultra-high-speed flight of objects
