In order to give full play to the advantages of the variable geometry and variable thermodynamic cycle of the variable cycle engine, it is necessary to optimize the performance of the engine according to different tasks. In this paper, the improved simulated annealing algorithm is used to solve the performance optimization problem of variable cycle engine for the first time. This optimization algorithm gives full play to the advantages of simulated annealing algorithm, and overcomes its time-consuming disadvantage by reducing the number of unreasonable calculations. At last, the simulation results show that the optimization based on the improved simulated annealing algorithm can not only achieve the same accuracy as the simulated annealing algorithm, but also can greatly reduce the amount of calculation, save a lot of time, and improve the calculation efficiency, which is more suitable for use in the optimization of variable cycle engines.
