Carrier Rocket Engine Working Process System Is Discussed

Although oux carrier rocket engine technology has obtained tremendousadvancement, it has much gap from the advanced country. The key factor whicheffects carrier rocket engine technology is the deficiency of the ability of research andirmovation in carrier rocket engine. Analying the current situation and thedevelopment trend of the carrier rocket engine technology in the world, combiningwith the characteristis of our rocket engine research institute, and searching theapproach that enhance the research and innovation abiIity of catrier rocket enginehave practical significance to accelerate technology progress and improvemanufacture level.The paper anaIyzes the key elements which affect the ability of rescarch andinnovation of different kinds of engines. The author raises the conception of carrierrocket engine working process research system: builds the structure model of carrierrocket engine working process research system by using the theory of operationaIresearch and systems engineering: analyzes this structure model by the analyticalhierarchy process: calculates the system element important degree and integrateimportant degree.The research result has some reference values to the rocket engineresearch institute building and strategy development.This paPer analyzes the environment both at home and abroad of the carrierrocket engine working process research of The l lth Research Institute of ChinaAerospace Science & Technology Corporation. The author puts fOrward themanagement mode and the strategy plan of the carrier rocket engine working processresearch system building. This paper studies the test research systems of key element.such as combustion process test research system. combustion instabi1ity test researchsystem, nozzle test research system, heat transfer and cooling test research system,and also sets up the building scheme of these elements.
