The steady state performance is optimized by combining multiple variables of variable cycle engine. The results of maximum thrust performance optimization in non-state-of-charge state are presented as an example. The results show that this optimization method overcomes the shortcomings of traditional optimization methods and optimizes the steady-state performance of variable cycle engine.
