Analysis of Burning Rate Phenomena and Extinguished Solid Propellants From an Interrupted Closed Bomb with Plasma Igniter

摘要

Interrupted closed-bomb analyses of M30 and JA2 propellants have been performed with the goal of understanding the phenomena responsible for the apparent augmentation of closed-bomb burning rates when plasma, rather than black powder, ignition is used. Burning rates of the propellants during plasma injection and after the plasma (to blowout pressures of 100 MPa) have been estimated from the grain regression measurements and the P-t traces. characterization of the extinguished grains has been performed in order to understand the interaction of the plasma with the propellant, including scanning electron microscopy (SEM) and the Fourier-transform infrared (FTIR) analyses.
