Abstract

We consider the problem of minimizing the fuel consumption of subsonic passenger and transport aircraft at the cruise flight phase. An optimization problem is stated to form the altitude and speed flight profile. It is proposed to solve this problem by the coordinate descent method (taking into account the constraints) combined with the use of a set of auxiliary candidate points. The calculation of fuel consumption as an objective function of optimization is realized by numerical modeling with a fixed step for speed and altitude transients and by a simplified calculation of the per second consumption based on the static equations on flight intervals with constant speed and altitude.

固定到达时间飞机巡航高度和速度剖面的优化

摘要

我们考虑在巡航飞行阶段将亚音速客机和运输机的油耗降至最低的问题。陈述了一个优化问题以形成高度和速度飞行剖面。提出通过坐标下降法（考虑约束）结合使用一组辅助候选点来解决这个问题。作为优化目标函数的油耗计算是通过具有固定速度和高度瞬变步长的数值建模以及基于恒定速度和高度的飞行间隔的静态方程的每秒消耗的简化计算来实现的。
