Title Design a passive rotary engine test device and test system
Abstract
The working conditions of solid rocket motor are varied.Sometimes, due to some special needs, the rotation is an important way of the rocket engine flight, and the acceleration of the rotation will have an effect on the work of the solid rocket motor:Cause deformation of the propellant and the housing, the combustion chamber and the nozzle in the gas flow change, impact on the combustion chamber pressure, mass flow rate and the specific impulse and the local areas of the engine heat transfer change, also make metal and metal oxide in propellant or engine shell deposition amount increases, rotation of the engine ignition process also affected。It has important significance for the design of the engine which can meet the overall requirements and the negative impact of the rotation.Therefore, the design of high-speed rotating test rig, the engine of the characteristics of different speeds of research, will play a great role.In this paper, the structure design of the high-speed rotating test rig is carried out, and the maximum speed of the engine measuring system can reach the test of the 10000rpm..
