Abstract

The system simulation model and the relevant multi-objective optimization model were established for a type of liquid propellants rocket engine

by hybrid algorithm and genetic algorithm.Aiming at FFSC

performance parameters of engine were optimized under kinds of different design variables and objective functions

and got the global optimum solutions.The calculation results showed that genetic algorithm was the most available method to solve such a type of problem

also it could be guidance for other similar engine optimization.
