Optimization design of hypersonic vehicle propulsion system based on ISIGHT and MATLAB

Abstract

Since the beginning of the 21st century, the anti-missile weapons of various countries in the world have continued to develop, and it is difficult for ordinary ballistic missiles to break through the end defenses of the anti-missile system. Therefore, hypersonic vehicles and missiles are born to deal with the application of powerful anti-missile systems. It is generally considered that an aircraft greater than five times the speed of sound is called a hypersonic aircraft. It is exactly because of its extremely high flight speed that high requirements are placed on the performance of the propulsion system of the aircraft. This paper takes the American X-43A hypersonic aircraft as the basic configuration and combines MATLAB to compile the optimization program to realize the multi-objective optimization and reliability design of the aircraft propulsion system in ISIGHT.
