Abstract

The problem of forming the altitude-speed profile of the flight of civil and military transport aircraft (AC) at the ascent stage and optimization according to the economic criterion is solved using a dynamic model of the motion of the center of mass in a vertical plane. The model takes into account the change in the mass of the AC and the systematic component of the wind speed. The aerodynamic characteristics of the AC and its weight, as well as the altitude and speed characteristics and the throttle characteristics of the engines, are close to those of a modern typical medium-range AC. For the given ascent scenario, the optimal and quasi-optimal control laws are found at the acceleration stage. The influence of the scenario’s parameters on the values of the main optimization criteria is estimated. The dependences of the optimal values of the ascent rate on the cost index are obtained and the range of its variability is found.

民用和军用运输机垂直导航问题优化上升阶段的方法和结果

摘要

利用质心在垂直平面运动的动力学模型，解决了在上升阶段形成民用和军用运输机（AC）飞行的高度-速度剖面并根据经济准则进行优化的问题。 . 该模型考虑了 AC 质量的变化和风速的系统分量。AC的空气动力学特性及其重量，以及发动机的高度和速度特性以及油门特性，都接近于现代典型的中程AC。对于给定的上升场景，在加速阶段找到最优和准最优控制规律。估计场景参数对主要优化标准值的影响。
