Abstract

The invention discloses a vertical ejection scaling test device constructed based on high-pressure air. The vertical ejection scaling test device comprises a compressed air supply system, an ejection system and a measurement and control system. The compressed air supply system produces and stores air for the test device before the test is started, and completes air supply, air stop and adjustment of the ejection system according to an instruction of the measurement and control system after the test is started; when the test is started, the ejection system receives an ejection instruction of the measurement and control system, and after the specified pressure is reached, the whole simulated missile system is ejected out of a barrel; and the measurement and control system sends instructions such as air supply and air stop to the compressed air supply system, acquires the acceleration of the simulated missile system and the pressure and temperature in the launch canister in real time in the canister outlet process of the simulated missile system, and performs storage, analysis processing and result display. According to the invention, a test platform is provided for air ejection related professions, the dynamic parameter research of the simulated missile system in the launching process in the launch canister is realized, and the approximately uniform acceleration and low-load vertical ejection scaling test of an ejection object in the launch canister is completed.

Description

technical field [0001] The invention belongs to the technical field of air ejection, and in particular relates to a vertical ejection scaling test device based on high-pressure air. Background technique [0002] As a new type of cold launch technology, compressed air ejection technology has the advantages of low cost, no pollution, flameproof, explosion-proof, anti-electromagnetic interference, good versatility, convenient maintenance, and no need for thermal protection measures. [0003] In recent years, with the wide application of compressed air ejection technology in the launch field, researchers in related fields have carried out more theoretical and simulation modeling calculations and analyzes on the dynamic parameters of the ejection process based on compressed air, but lack of targeted In particular, there is no low-load ejection test device based on high-pressure air, so it is impossible to realize the comparative verification of theory and experiment. Therefore, ...
