针对飞机地面滑行位置、姿态等行为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机场滑行道几何约束和非完整运动学约束下飞机地面滑行运动计算方法。依据地面滑行几何约束,对飞机前轮转弯角进行解析推导,设计出适合仿真推演计算的飞机地面运动求解方法。依据非完整运动描述方程,设计出在开环控制下飞机地面运动求解方法。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。通过数学仿真验证了方法的有效性。
Aiming at the behavior calculation of aircraft taxiing position and attitude, the paper studies the problem. From the perspective of airport tower control simulation, the calculation method of aircraft ground taxiing movement under geometric constraints and nonholonomic kinematic constraints of taxiway is proposed. According to the geometrical constraints of the taxiway on the ground, the turning angle of the front wheel of the aircraft is analyzed and derived, and the solution method of the aircraft ground movement suitable for the simulation and deduction calculation is designed. According to the non-complete motion description equation, the method of solving the ground motion of 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 by mathematical simulation.
