Acceleration process optimization control research was conducted based on the variable vane adjustment and feasible sequential quadratic programming (FSQP) algorithm. Using the adjustment of the guide vane during acceleration

the air mass flow of high pressure compressor and fan can be optimized. In this case

the fuel flow can be increased at a faster speed. Thus

the acceleration performance was significantly enhanced. Then

compared with conventional two-variable (fuel flow and nozzle throat area) optimization method

three-variable optimization method simulations were carried out based either on guide vane of fan or on that of high pressure compressor. The results show that fuel flow rate is better than the traditional ways. Moreover

the guide vane of high pressure compressor plays a more important role than that of fan during the process. The acceleration pass after optimization is close to the surge margin boundary with restraint in the feasible region. The acceleration time of the three methods are 5.5s

4.9s and 4.5s respectively.
