Control method of aseismic airbag of fixed-wing unmanned target aerial vehicle

Abstract

The invention relates to a design of a control device of an aseismic airbag of a fixed-wing unmanned target aerial vehicle, relates to a control technology of the aseismic airbag of the fixed-wing unmanned target aerial vehicle, and is a solution scheme for realizing safe landing shock absorption of the fixed-wing unmanned target aerial vehicle. For realizing safe landing shock absorption of the fixed-wing unmanned target aerial vehicle, the aseismic airbag needs to be quickly inflated to the optimal state. The optimal internal pressure of the aseismic airbag which can achieve the best shock-absorbing effect is calculated in real time according to the height, temperature, fuel consumption, speed, acceleration and other information of the fixed-wing unmanned target aerial vehicle, and the optimal internal pressure is taken as a target pressure; the internal actual pressure of the aseismic airbag and the actual rotation speed of inflation fans are acquired meanwhile, the actual rotationspeed of the inflation fans are controlled by a control algorithm to enable the internal pressure of the aseismic airbag to quickly reach the optimal internal pressure; and finally, when the fixed-wing unmanned target aerial vehicle is landed, the control over the aseismic airbag is automatically stopped to prevent continuous inflation from damaging the device. The design is mainly used for safe landing shock absorption of the fixed-wing unmanned target aerial vehicle.

Description

technical field [0001] The invention relates to a control method for a shock-absorbing airbag of a fixed-wing unmanned target drone, which is mainly used for the safe landing of the fixed-wing unmanned target drone for shock absorption. Background technique [0002] During the landing and recovery process of the fixed-wing unmanned target drone, when the fixed-wing unmanned target drone opens the parachute, the shock-absorbing airbag must be opened in time to ensure that the shock-absorbing airbag can play a shock-absorbing role when the fixed-wing unmanned target drone lands. In order to prevent the fixed-wing unmanned target drone from being too impacted at the moment of landing, causing damage to the body and causing huge losses. At present, most of the shock-absorbing airbags of fixed-wing unmanned target drones use the method of igniting the explosives inside the gasbag, so that the airbags are inflated instantly, so as to ensure that the fixed-wing unmanned target dron...

Problems solved by technology

However, the current airbag pressure is fixed, which cannot meet the shock absorption requirements of fixed-wing unmanned target drones at different altitudes, and may even cause damage to the target drone.
