Dual reactive gas driven high-speed launching system

Abstract

A dual reactant gas driving high-speed launching system comprises a launching tube (1) containing pills (2), a reaction chamber and a film (3) arranged between the reaction chamber and the launching tube (1). The dual reactant gas driving high-speed launching system is characterized in that a piston (7) is arranged in the reaction chamber and divides the reaction chamber into a reaction chamber zone I (5) and a reaction chamber zone II (4). The film (3) is located at the end of the reaction chamber zone II (4). An ignition element (6) is arranged in the reaction chamber zone I (5). An ignitionelement (8) is also arranged in the reaction chamber zone II (4). Detonation matter is injected in the reaction chamber zone I (5). Detonation matter is injected in the reaction chamber zone II (4) too. The dual reactant gas driving high-speed launching system adopts an effective method capable of greatly increasing the initial pressure and energy density without the need for a booster pump, theimplementation structure is simple, and the gas high-energy density state can be obtained conveniently and rapidly, and therefore high-speed pill launching is realized.

Description

technical field [0001] The invention belongs to the technology of reactive gas driven light gas cannon. Background technique [0002] Among the dynamic loading systems for the study of high-pressure material properties, dynamic response, and high-speed collisions, light gas cannons and artillery loading systems have been widely used because of their advantages such as large pressure adjustment range, high experimental accuracy, and low requirements for site conditions. In the research of dynamic launch technology, how to improve the launch efficiency of the system and obtain a higher temperature and pressure state to achieve a higher launch speed is always the core issue. [0003] Reactive gas-driven light gas cannon technology is the use of low-molecular-weight combustible mixed gas to react and release energy to propel projectiles so that they can obtain higher-speed launch technology. It uses two or more gases, such as hydrogen, methane, etc., to react with oxygen to rel...

Problems solved by technology

[0004] However, the density of the gas is small, and the energy released by the unit volume of the gas reaction (that is, the energy density) is low. To obtain a higher energy density, the method of reducing the initial temperature or increasing the initial pressure can be adopted. Reducing the initial temperature involves a complex cryogenic system. , the price is expensive, and for the initial 300K gas, even if the temperature is reduced to 77K in the liquid nitrogen temperature zone, under the ideal gas assumption, the gas density (unliquefied) will only increase by a little more than 3 times. Initial pressure is a more efficient way to increase energy density

If an ordinary booster pump is used to increase the gas pressure, there are problems such as limited final pressure, bulky equipment, and rapid decrease in efficiency as the gas pressure in the container increases.
