Abstract

Experimental studies on ram accelerator starting processes were conducted using a 25-mm-bore ram accelerator installed at Shock Wave Research Center, Institute of Fluid Science, Tohoku University. Necessary starting conditions for the thermally choked propulsive mode are discussed on. Ram acceleration was realized, yielding a velocity gain of 350m/s. Shock heating processes before and during diaphragm rupture by a projectile were visualized by high-speed photography, thereby supporting a conclusion made by Burnham that the shock-heated slug can play as an ignitor to the mixture.
