Transverse flight energy management method of unpowered aircraft

Abstract

The invention discloses a transverse flight energy management method of an unpowered aircraft, and relates to the technical field of aircraft flight control. The method comprises the following steps:calculating a transverse deviation amount according to a transverse position deviation and a transverse speed deviation of an aircraft for a standard flight path, and obtaining a direction cumulant through calculation, wherein the direction cumulant represents a position deviation direction of the aircraft; according to the direction cumulant and a speed deviation amount, calculating a transversespeed guide amount; performing an inertial link and a proportional link on the transverse position deviation to obtain a transverse position guide amount; and performing weighted summation on the transverse speed guide amount and the transverse position guide amount to generate a transverse guide instruction, and controlling transverse flight of the unpowered aircraft. According to the method disclosed by the invention, the transverse speed deviation and the transverse position deviation are comprehensively considered based on the standard flight path; transverse guide is fused with speed control; and excess fuel is consumed in a maneuvering manner transversely, so that over-adjustment is avoided, and energy management of the aircraft is realized.

Description

technical field [0001] The invention relates to the technical field of aircraft flight control, in particular to a lateral flight energy management method of an unpowered aircraft. Background technique [0002] When an unpowered aircraft performs long-distance and long-distance flight missions, the energy deviation caused by the deviation of aerodynamic parameters and atmospheric density will accumulate over time, eventually leading to excessive energy dispersion at the end, and even causing the trajectory to diverge during the flight. It is beneficial to the later task handover. Therefore, it is necessary to manage the energy of the aircraft, control the energy accumulation deviation, and prevent the trajectory from diverging. [0003] The energy of the aircraft is designed according to its maximum flight range. For general tasks, there will be a certain amount of energy surplus. Existing aircraft energy management methods are mainly to continuously predict the flight tra...
