摘要
建立了综合飞行 /推进系统的数学模型 ,介绍了飞机全维非线性数学模型和涡轮风扇发动机非线性部件级数学模型的建模及综合方法。对飞机执行地形跟随任务时 ,飞行员调节飞行速度的方法与基于总能量的调节飞行速度的方法进行了比较。结果表明 ,基于总能量的方法比飞行员直接控制飞行速度能够减小发动机的燃油消耗 ,降低发动机的磨损 ,进而可以增加飞机的航程 ,延长发动机的使用寿命。
Mathematics model of integrated flight/propulsion system is developed in this paper Both the nonlinear model of plane and the nonlinear component model of turbofan engine are introduced, and their synthesis method is discussed Velocity regulation in low altitude penetration using different method, such as by pilot and by total energy management, is discussed also The result of simulation indicates that the efficiency of engine is improved and wear of engine is reduced by total energy management method, so both the flight range and the life of engine are prolonged
