摘　　要：分析了发动机加力状态燃油消耗的特点,利用主燃烧室燃烧效率远大于加力燃烧室燃烧效率的特点,将性能寻优控制中的最小油耗模式扩展至加力状态.用线性规划(Linear Programming)算法进行发动机性能寻优.进行了加力状态最小油耗模式的数字仿真实验,仿真结果表明在加力状态应用最小油耗模式,可以使单位耗油率减少5%～7%,其效益远高于非加力状态的最小油耗模式,具有明显的实际应用价值.The characteristic of fuel consumption at aero-engine afterburning condition was analyzed. Based on the fact that the efficiency of main combustor is higher than that of the afterburner, this article puts minimum fuel consumption mode into use at aero-engine afterburning condition. Linear Programming was used to optimize the aero-engine performance. Digital simulations show that the specific fuel consumption was decreased by 5% - 7%. The benefit of minimum fuel consumption mode at afterburning condition is much more than that of non-afterburning condition. It has great application potential in engineering.
