Relationship between Plasma Energy and Gas Generation in an Electrothermal-Chemical Gun

摘要

A scheduled relationship between plasma energy (electrical energy) and the gasgeneration (decomposition) of the propellant in the combustion chamber of an electrothermal-chemical (ETC) gun is one of the key factors in controlling the ETC interior ballistic cycle. This relationship is investigated by using an inverse analysis model, which computes the gas generation of the propellant to analyze ETC experimental data. A heat loss function is included in the model for this investigation since heat loss is a significant factor in small-caliber guns.
