A kind of target drone flight control system and flight control method

Abstract

The invention provides a drone aircraft flight control system and method. The drone aircraft flight control system comprises a flight execution unit, a sensor unit and a flight control unit. By means of the relation existing among the wing area, the drone aircraft lift force and the flight rotating speed, the swing angle of a leading edge flap and a leading edge flap is controlled strictly, so that power consumption of an aircraft engine is reduced while enough drone aircraft lift force is ensured.

Description

technical field [0001] The invention belongs to the field of flight control of aircraft, in particular to a flight control system and a flight control method for a target aircraft. Background technique [0002] The flight control system of the target aircraft is a typical nonlinear, strongly coupled, and multivariable system. The slight changes of each variable will have an impact on the flight attitude, flight direction, flight altitude, flight lift and power of the target aircraft. How to make the target aircraft Maintaining a high-lift and high-stability flight state is an urgent technical problem in the field of target drones; most target drones are equipped with high-lift devices on the wings, which mainly include leading edge flaps and trailing edge flaps; The operation method of the high-lift device of the target aircraft is all manually operated by the pilot to control the swing of the leading edge flap and the trailing edge flap. The workload is heavy. Once the tar...

Problems solved by technology

However, most of the leading edge flaps and trailing edge flaps disclosed in the prior art are retracted or put down or swing manually, and are also controlled according to the deflection angle of the high-lift device, but these flight control systems cannot accurately control the front flaps. The timing of the swinging of the edge flaps and trailing edge flaps, and how many angles of swinging can make the target aircraft change from the state of the stall angle of attack to the flight state of the high angle of attack
