Aircraft ground taxiing behavior calculation method

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。

The aircraft behavior computational problems are studied aimed at taxiing position and attitude.Aircraft taxiing movement calculation method constrained by taxiway geometry and nonholonomic kinematics is proposed from the perspective of airport tower control simulation.According to taxiway geometry constraint,we analyze nose gear steering angle variation and design an aircraft ground movement algorithm suitable for simulation-driven.According to nonholonomic kinematics equations,we design a mathematic method to describe aircraft ground movement maneuver under the open-loop control.Compared with dynamics model,the method we proposed has the advantages that are easier to calculate and more suitable to drive visual simulation.The validity of this method is verified by mathematic simulation.
