通过分析水平面内的最快转弯和最小半径转弯,研究了现代战斗机的最优过失速机动和高速机动。利用最优控制理论,讨论和分析了最优倾侧角控制和推力控制规律。典型示例飞机的数值仿真计算结果表明,最优高速转弯轨迹是B、C和S等各段子弧的相应组合,它与发动机推力、飞行高度、端点马赫数、过载和空气动力约束等相关;提高发动机推力亦可减小最优转弯时间。
By analyzing the fastest turning and the smallest radius turning in the horizontal plane, the optimal flipping maneuver and high speed maneuver of modern fighter are studied. Using the optimal control theory, the optimal roll angle control and thrust control law are discussed and analyzed. The numerical simulation results of a typical example aircraft show that the optimal high-speed turning trajectory is a corresponding combination of sub-arcs of segments B, C and S, which is related to engine thrust, flight altitude, end point Mach number, overload and aerodynamic constraints; Engine thrust can also reduce the optimal turn time.
