飞机最快上升转弯轨迹的计算

70年代初,Miele A等人提出SGRA方法用于优化飞行轨迹计算。但方法存在时间加权系数难于确定、长时间的飞行轨迹计算积分精度不易控制及要计算数字微分等不足。对此提出一改进梯度方法,并计算了某型战斗机从亚音速三维转弯升高到超音速的最短时间飞行轨迹。结果表明,本方法稳定有效,为解决飞机最快机动轨迹的优,乜提供了一种行之有效的手段。

MINIMUM TIME 3-D FLIGHT TRAJECTORY COMPUTATION

In early 70s,Miele A et al developed the SGRA method for the optimal flight trajectory computation,but there are some shortages in determining the time weighting,controlling the integral precision and requiring a numerical differential.This article presents a modifying gradient method,and the fastest 3-D turning trajectory from subsonic to supersonic is calculated.It is turned out that this method is stable and efficient.This method provides an efficacious algorithm for optimizing the flight trajectroy.
