Problems solved by technology

[0004] However, the unmanned aerial vehicle carrying and taking off faces a severe control problem, that is, the moment the unmanned aerial vehicle and the carrying platform are separated, the unmanned aerial vehicle itself has no initial velocity. At this time, the rudder effect of the unmanned aerial vehicle itself does not work. The control system cannot make corrections to the attitude of the UAV in time.
In this way, when there is an external disturbance at the moment of launch, it may cause the fuselage to roll over, which directly leads to the failure of this mission

Embodiment Construction

[0029] Based on the existing technology, when the UAV is separated from the carrying platform, its initial velocity is zero. At this time, the rudder effect of the UAV itself does not work, and the attitude of the UAV is uncontrollable. There may be a problem that the attitude rolls and the mission fails. The invention provides a method and device for acquiring the initial velocity of the drone when it is launched. During the ascent process, the height of the carrying platform is monitored in real time. When the height of the carrying platform reaches the predetermined launch height, the fixed component is released to allow the drone to be pulled by the fixed component. Automatically slide down; when it is detected that the speed of the drone reaches the controllable scheduled release speed, the fixed components of the fixed drone are cut, the drone is released, and then the drone is adjusted by the control system of the drone itself attitude, so that the UAV can achieve a stab...

Abstract

The present invention provides a method for acquiring the initial velocity of the unmanned aerial vehicle, including: monitoring the height of the platform carrying the unmanned aerial vehicle during the ascent process; The fixed component of the UAV, so that the UAV slides under the traction of the fixed component; man-machine. The invention also discloses a device for acquiring the initial velocity when the drone is dropped. The invention can make the unmanned aerial vehicle have a certain initial speed when leaving the carrying platform for delivery, and the device is simple, the cost is low, and it is easy to realize.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a method and device for acquiring the initial velocity of an unmanned aerial vehicle when it is launched. Background technique [0002] Near space refers to the airspace 20-100km from the ground, which is located between space-based satellite platforms and aviation drone platforms, and has not received special attention for a long time. However, the adjacent space has great potential value in military applications. The atmospheric density in this part of the space is thin, and most of the fixed-wing drones and surface-to-air missiles in the world cannot reach this altitude. Aircraft in the adjacent space are under attack. At the same time, because the altitude of this part of space is much lower than the operating altitude of ordinary satellites, it provides favorable conditions for intelligence reconnaissance, collection and communication. Near space is an important stra...
