AI Technical Summary

Problems solved by technology

If the propeller is engaged with the engine inside the launch box, it will damage the drone and the launch box; if the drone is launched and engaged too late or not reliably engaged after leaving the launch box, it will cause insufficient or no thrust after launch of the drone cause stalls, crashes, etc.
At present, no relevant patents have been found for the automatic control device for box-launched UAV engine and propeller meshing

Abstract

The invention relates to an automatic control device for meshing of an engine and a propeller of a box-type launching unmanned aerial vehicle, which adopts a minimum application system taking a microprocessor as a core, designs an electrical interface of a controller, can set time data according to meshing time of different engines and propellers, and ensures reliable meshing of the engines and the propellers. Meanwhile, two paths of in-place signals are designed to prevent the situation that a control circuit misjudges that the unmanned aerial vehicle is in a launching state and mistakenly controls meshing of an engine and a propeller.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle control, and relates to an automatic control device for a box-type launched unmanned aerial vehicle capable of automatically controlling the meshing of an engine and a propeller. Background technique [0002] Box-launched UAVs are usually kept in launch boxes. When launching, first start the UAV engine in the launch box. Due to the height limitation of the launch box, after the engine starts, the propeller is not allowed to rotate with the engine, and the UAV is in a state where the engine and the propeller are not meshed; when the UAV launches and leaves After the launch box, the automatic control device for the meshing of the UAV engine and the propeller will control the meshing of the engine and the propeller, and the propeller rotates with the engine to provide thrust for the flight of the UAV. If the propeller is engaged with the engine inside the launch box, it will damage t...
