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

Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention are clearly and completely described below.

[0023] According to the calculation method described in the present invention, calculate false angle of attack, in order to illustrate the validity of false angle of attack, in the simulation of aircraft six degrees of freedom, the normal angle of attack of the false angle of attack of construction and aircraft equation output is compared, figure 1 It is the simulation comparison when the simulation time is 2s ~ 6s when the half rod is pulled longitudinally, figure 2 For the simulation comparison when the rod is fully stretched longitudinally, image 3 It is a simulation comparison of pushing the full pole vertically.

[0024] From the simulation results, it can be seen that the response polarity of the false angle of attack is correct during maneuvering, and there is basically no delay. In the manipulation of small and medium sticks, the response amplitud...

Abstract

The present invention provides a method for driving a speed vector indicator for a human-in-the-loop HUD display of an unmanned aerial vehicle. The ground control platform uses the effective normal overload information downloaded by the UAV to construct a pseudo angle of attack, which is used to simulate the real angle of attack, so that the false angle of attack can be used to drive the head-up display speed of the integrated flight control screen display area of ​​the ground control platform Vector symbols are displayed. In the above method, the polarity of the false angle of attack response is correct during the maneuvering process of the UAV, and there is basically no delay. In the manipulation of small and medium sticks, the response amplitude basically coincides with the normal angle of attack. When the large stick is manipulated, the response amplitude is slightly smaller than normal. The angle of attack meets the requirements of use.

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...
