军用飞机最大故障速度计算

Calculation of maximum failure speed of military aircraft

根据故障速度计算原理,建立飞机运动仿真模型,重点结合刹车、气动、发动机及起落架系统模型编写运算程序,对飞机加速滑跑段和刹车停止段进行仿真计算。以某型军用飞机为例,建立基于4阶龙格-库塔法(Runge-kutta)的高精度模型求解器进行求解,给出军用飞机最大故障速度计算方法。该算法计算结果与实际试飞数据拟合较好,可为部队实际训练提供参考。

According to the calculation principle of failure speed,an aircraft motion simulation model is established.The key point is to combine the brake model,pneumatic model,engine model and landing gear system model,and to compile the calculation program to simulate the aircraft’s acceleration run-off section and brake stop section.Taking one military aircraft as an example,a high-precision model solver based on the fourth-order Runge Kutta method is established,and the calculation method of the maximum failure speed of military aircraft is given.Calculation result of the algorithm can well fit the actual test flight data,providing reference for the actual training of troops.
