摘　　要：巡飞弹常采用微型涡喷发动机,需完成长时间的巡逻飞行任务,为实现典型航迹飞行,全弹质量变化率将不断变化,文中分别建立了两种典型航迹下巡飞弹燃油消耗质量的数学模型,其中构造了代理模型来计算气动力参数和燃油耗油率(SFC)。经算例仿真计算,得到了典型航迹下巡飞弹质量消耗的变化规律,以及对应的推力控制律和需用攻角变化律,所建立的燃油质量消耗数学模型可用于巡飞弹总体设计之中。Scout missile used micro turbojet engine mostly, loitering on the search region for a long time. Mass variation of scout missile varied to keep the representative trajectory. The paper established fuel mass consumption methods of scout missile in two representative trajectories, and constructing the surrogate model of aerodynamic coefficient and SFC. The rule of mass consumption, propulsion and attack angle was educed by simulation in representative trajectory. Fuel mass consumption model established in the paper can be used in preliminary design of scout missile.
