Embodiment Construction

[0025] The basic process of the firing of the third-stage light gas gun: high-pressure nitrogen is stored in the first-stage gas chamber 1, and the high-pressure gas in the first-stage gas chamber 1 is released instantaneously through the quick opening valve 7 during launch, the high-pressure gas drives the first-stage piston 8 to move, and the first-stage piston 8 Compress the gas in the primary pump tube 2 to the secondary gas chamber 3 to a high-pressure state, the secondary diaphragm 9 ruptures under a certain pressure, the primary pump tube 2 gas drives the secondary piston 10 to move, and the secondary piston 10 compresses the secondary The gas in the pump tube 4 reaches the third-stage gas chamber 5 to a high-pressure state, the third-stage diaphragm 11 ruptures under a certain pressure, and the second-stage pump tube 4 gas drives the projectile 13 to accelerate in the launch tube 6, and the projectile 13 accelerates to the target speed.

Abstract

A three-level light-gas gun driven by compressed nitrogen comprises a primary gas chamber, a primary pump tube, a secondary gas chamber, a secondary pump tube, a tertiary gas chamber and a transmitting tube. The primary gas chamber is connected with the primary pump tube, and a quick opening valve is arranged between the primary gas chamber and the primary pump tube; the primary pump tube is connected with the secondary gas chamber; the secondary gas chamber is connected with the secondary pump tube, and a secondary diaphragm is arranged between the secondary gas chamber and the secondary pump tube; the secondary pump tube is connected with the tertiary gas chamber; and the tertiary gas chamber is connected with the transmitting tube, and a tertiary diaphragm is arranged between the tertiary gas chamber and the transmitting tube. A three-level driving mode is adopted, energy utilization efficiency among levels is improved, a severe gas environment in a gun body is improved, and ablation risks of the gun body are reduced; the secondary gas chamber and the tertiary gas chamber are of straight barrel type structures or barrel structures with large cone angles, and the energy utilization efficiency is improved; and a replaceable ablation ring is arranged at the front end of the transmitting tube, the ablation risks of the gun body are reduced, and experimental cost of super-speed transmission is greatly reduced.

Description

Technical field [0001] The invention relates to a three-stage light gas gun, in particular to a three-stage light gas gun driven by compressed nitrogen. Background technique [0002] Light gas guns can launch materials and projectiles of various shapes to meet the needs of various end-point benefit simulation tests. It is known as the most versatile high-speed and ultra-high-speed driving technology. It is widely used in kinetic energy weapon effect research, geospatial physics research, and spacecraft. Protection research and other fields. Compared with the first-level light gas gun and the second-level light gas gun, the third-level light gas gun adopts a three-stage drive mode. [0003] McGill University in Canada has developed a gunpowder-driven three-stage light gas gun with an inner diameter of 12.7mm, which accelerates 1.5g and 1.1g polyester cylindrical projectiles to 9.6km / s and 10.5km / s respectively. The University of Dayton Research Institute in the United States has a...
