Abstract

The invention discloses a high-maneuverability turning energy control method for a high-speed plane symmetric aircraft, a medium and equipment, and belongs to the technical field of aircraft guidancecontrol. The invention aims to solve the problem that a high-speed plane symmetric aircraft needs to consume energy and adjust the course through long-time large rolling maneuver in a test area, guarantees that the aircraft enters a landing area at the end point of the energy management section, provides an online energy management method without a large number of iterative computations, and solves the problems that when the aircraft is separated from boosting, energy dispersion is large, and missile-borne aircraft computing resources are limited. In the energy management section, the aircraftmakes large maneuvering turns in opposite directions twice to bend the trajectory, energy is consumed in the maneuvering process, the course is adjusted, and finally the aircraft enters a landing area.

Description

technical field

[0001] The invention relates to a method, medium and equipment for controlling large maneuvering turning energy of a high-speed plane symmetrical aircraft, and belongs to the technical field of aircraft guidance and control. Background technique

[0002] During the flight test of the high-speed surface-symmetric aircraft, the booster is sent into the test window, and then the aircraft is separated from the booster to carry out the flight test. Bending, energy is consumed during maneuvering, heading is adjusted, and the aircraft enters the landing zone at the end of the energy management segment.

[0003] Existing energy management methods need to pre-store ballistics in the missile-borne aircraft, which requires high storage resources for the missile-borne aircraft; online prediction of the remaining range is required, which requires high computing resources for the missile-borne aircraft. Existing energy management methods do not consider the influence of t...

Embodiment Construction

[0034] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as image 3 As shown, a high-speed surface-symmetrical aircraft large-scale maneuvering energy control method, after the aircraft completes the preset task, it performs two roll maneuvers in opposite directions to realize the aircraft turning, so that the energy of the aircraft after performing the two roll maneuvers and heading meet the terminal guidance conditions, and then carry out terminal guidance control on the aircraft, so that the aircraft enters the landing zone.

[0036] Preferably, the aircraft flies in BTT mode during turning.

[0037] Specifically, the aircraft range x-horizontal range z is as follows figure 1 shown. Vehicle Range X - Roll Angle Command¶ c Instructions such as figure 2 shown.

[0038] Point A is the separation point between the aircraft and the booster.

[0039] Section A-B is the...
