A lateral flight energy management method for unpowered aircraft

Abstract

The invention discloses a lateral flight energy management method of an unpowered aircraft, which relates to the technical field of aircraft flight control. Obtain the cumulative amount of direction; the cumulative amount of direction indicates the position offset direction of the aircraft; calculate the lateral velocity guidance amount according to the cumulative amount of direction and speed offset; pass the lateral position deviation through the inertia link and the proportional link to obtain the lateral position guidance amount ; Carry out weighted summation of the lateral speed guidance amount and the lateral position guidance amount to generate a lateral guidance command to control the lateral flight of the unpowered aircraft. The present invention takes the standard track as the reference, comprehensively considers the lateral velocity deviation and the lateral position deviation, combines lateral guidance with speed control, dissipates excess fuel through lateral maneuvering, avoids over-adjustment, and realizes energy management of the aircraft.

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...
