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...

Problems solved by technology

In the existing energy management method, when designing the range-energy profile, the calculation is simple, and the influence of the roll angle of the aircraft on the range is not considered, that is, the vertical and horizontal decoupling design

This design method will lead to a larger prediction of the flight range, because a larger roll angle will accelerate the speed of the aircraft's descent, increase the dynamic pressure of the aircraft, thereby accelerating energy loss and shortening the flight range

In order to reduce the deviation of the range, the aircraft cannot do long-term large roll maneuvers under this design method, so that the deviation of the range prediction can be controlled within an acceptable range, but this limits the maneuverability of the aircraft
