A compressed air ejection experimental device for simulating missile ejection

Abstract

A compressed air ejection experimental device for simulating missile ejection comprises an ejection device, a measurement and control system, an air compressor, an air supply system and a UPS power supply. Before the experiment starts, the ejection device is filled with simulated projectiles; when the test starts, adjust the launch angle, and eject the simulated projectiles out of the cylinder when receiving the ejection command from the measurement and control system; the air supply system starts or stops supplying the ejection device to the ejection device Air; the air compressor inflates the gas cylinder before the experiment; the measurement and control system sends adjustment instructions and ejection instructions to the ejection device, and during the process of simulating the ejection of the ejection barrel, the displacement of the simulated ejection, the pressure and temperature of the ejection barrel are collected in real time, and carried out storage, analysis and display of results. The UPS power supply supplies power for the ejection device, measurement and control system and air supply system. The invention provides an experimental platform for the relevant professions of air ejection, can study the dynamic parameters of the simulated projectile launching process in the launch tube, and realize the scaling test of the missile launch process in the launch tube.

Problems solved by technology

[0003] With the widespread use of compressed air ejection technology in the field of missile launching, researchers in my country's military colleges and universities have carried out theoretical analysis and simulation calculations on the dynamic parameters of the missile ejection process. Due to the lack of ejection experimental equipment, the theoretical analysis results cannot be verified experimentally.
