摘要
利用B样条曲线的几何性质,解决了飞行器三维航迹拟合中的边界条件等约束问题。并且通过求解分析B样条曲线的曲率与飞行器按规划三维航迹飞行的需用过载之间的数学关系,推导给出了所规划三维航迹的可飞性过载判断准则。最后,通过具体算例对某型飞机按拟合三维航迹飞行的需用过载进行实时仿真并判断该拟合三维航迹的可飞性。
This paper uses the method of B-Spline curvefittig to optimize the three-dimensional trajectory of a certain fighter plane. It makes use of the advantages of B-Spline to solve the problems which occur when the limit conditions of track are given. By comparing the curvature of B-Spline with the overloading needed by the flight track, this paper deduces a mathematic model as the overloading rule of flying craft needed. Through an ensample, it simulates the overloading of certain kind of aircraft flying along the tridimensional trajectory curvefitted by using this method.
