摘　　要：针对高超声速滑翔飞行器,利用理论推导和数值仿真的方法分析经典控制律中倾侧角对飞行速度、飞行高度、过程约束的影响。在平衡滑翔条件下,通过理论推导得出飞行速度、飞行高度、过程约束与倾侧角之间的解析式。仿真结果表明,理论推导的解析式具有较高的精度,解析解可以表征飞行速度、飞行高度和过程约束的变化规律。初始速度相同时,倾侧角越大,飞行速度、飞行高度、热流密度下降越快,动压和过载越大。在跳跃滑翔条件下,初始速度相同时,倾侧角越大,飞行速度下降越快,飞行高度和过程约束的波动变化幅度越小。Aiming at a hypersonic glide vehicle, the methods of theoretical derivation and numerical simulation are used to analyze the influence of the bank angle on flight speed, flight altitude and process constraints in the classical control law. Under the condition of equilibrium glide, the analytical formula between the flight speed, flight altitude, process constraints and bank angle is derived. The simulation results show that the analytical solution has superior accuracy, and the analytical solution can be used to characterize the change law of flight speed, flight altitude and process constraints. With the same initial speed, the greater the bank angle is, the faster the decline of the flight speed, flight altitude and heating rate is, and the greater the dynamic press and load factor are. Under the condition of skip glide, with the same initial speed, the greater the bank angle, the faster the decline of the flight speed, and the smaller the fluctuation of the flight altitude and the process constraints.
