Experimental Research of The Pulse II Ignition Impact Process of Double Pulse Motor

Abstract

Based on the pulse II transient ignition process of double pulse motor, in this paper, the cooling gas impact experiment platform was used to study the transient impact of the pulse II ignition pressure peak on the double pulse motor. The cooling gas impact experiment platform of double pulse motor and two different types of test motor were designed and manufactured. The test was carried out under different conditions such as the pressure of gas storage tank and the number of interstage hole. The motion law of the plugs in the pulse I combustion chamber are found out by high speed imaging technology. The results show that the blowout pattern and the motion law of the plug under the pressure (0.5MPa, 1MPa, 1.5MPa) of gas storage tank.
