Because it is complicated to confirm the performance parameter of variable cycle engine, the optimization performance parameter of variable cycle engine was presented. The performance optimization model of engine with constrained conditions was set up, then, use the search algorithm, the parameters were acquired, based on the minimum fuel consumption rate and maximum unit thrust of engine. At last, the variation principle between Mach number and parameters was given. The analysis results show the stability of the optimization model.
