Research on Potential Equilibrium of Dynamic Combustion Performance in Electrothermal-Chemical Launching

Abstract The interior ballistic potential equilibrium theory is used to analyse the parameters at points of pressure curves 30mm conventional launching experiment and electrothermal-chemical (ETC) experiments. Analysis shows that: compared experiment, (1) time for ETC arrive point apparently shortened; (2) relative burnt percentages propellants are smaller in tests. And gas generation brisance three experiments consistent. Then based on measured curves, actual functions chamber fitted respectively. Using average replace shape which derived from hypothesis Geometric Combustion Law, similarity equations Gun established with as reference state. calculated curve obtained by solving electrothermal chemical gun good agreement experimental curve. Therefore, it expected that could predict
