Speed vector directive driving method for unmanned aerial vehicle human-in-the-loop head-up display

Abstract

The invention provides a speed vector directive driving method for unmanned aerial vehicle human-in-the-loop head-up display. According to the method, under the condition that no effective attack angle signal is measured, according to the correlation derivation of angle-of-attack change and normal overload increment, a pseudo angle of attack is constructed on a ground console by using effective normal overload information downloaded by an unmanned aerial vehicle to simulate a real angle of attack, so that the pseudo angle of attack is used for driving the display of a head-up display speed vector directive of a flight control comprehensive picture display area of the ground console. According to the method, the response polarity of the pseudo angle of attack is correct and basically free of delay in the maneuvering process of the unmanned aerial vehicle, the response amplitude basically coincides with that of a normal angle of attack in the operation of medium and small rods, and the response amplitude is slightly smaller than that of a normal angle of attack in the operation of a large rod, so that the use requirements are met.

Description

technical field [0001] The invention belongs to the field of aircraft avionics, in particular to a method for driving a speed vector indicator for a UAV HUD display. Background technique [0002] In the design of UAV operation and control, refer to the display effect of the head-up display in the cockpit of the manned aircraft, refer to the human-in-the-loop control similar to the manned mode, and add or replace the specific flight parameters of the UAV in detail processing, real-time display The current flight environment of the UAV provides the operator with important information required for flight control and provides an important guarantee for the safe flight of the aircraft. [0003] In the display area of ​​the UAV flight control comprehensive screen, the use of the speed vector symbol is very important. By observing the relative positional relationship between the symbol and the horizon, the UAV operator can easily grasp the change of the current flight altitude of t...

Problems solved by technology

[0004] However, for UAVs, considering the cost of use or measurement accuracy, the angle of attack sensor is generally not installed, and it is difficult to obtain the real angle of attack of the UAV. A relatively reliable pseudo-attack angle must be calculated through other signal construction methods. angle for drive velocity vector sign
