针对飞机推出和跑道掉头两种地面滑行特殊行为的位置和姿态计算问题进行了研究。从机场塔台管制运行模拟仿真的角度出发,提出了非完整运动学约束下飞机推出滑行和跑道掉头运动计算方法。依据飞机推出实际和非完整运动路径跟踪模型,设计出适合仿真推演计算的飞机推出运动求解方法。根据飞机跑道掉头的几何约束和转弯角运动约束,设计出开环控制下完整刻画飞机运动的求解方法。与动力学求解模型相比,该方法具有计算简便,适合于视景仿真驱动的优点,并通过数学仿真验证了方法的有效性。
The position and attitude calculation problems of two kinds of special behaviors of ground taxiing are introduced in this paper. From the perspective of airport tower control simulation, the calculation method of aircraft taxiing and runway turnout under nonholonomic kinematic constraints is proposed. According to the actual and incomplete trajectory tracking model introduced by the aircraft, an aircraft launch kinematic solution method is designed to simulate the deduction and calculation. According to the geometrical constraints of U-turn on the runway and the constraints on the turning angle, a solution to describe the movement of the aircraft under open-loop control is designed. Compared with the kinetic solution model, this method has the advantages of simple calculation and suitable for visual simulation driving. The effectiveness of the method is verified through mathematical simulation.
