The application provides a kind of cruising
attack type unmanned aerial vehicle starting protection method and device.The method comprises: before box launching, starting engine and maintaining its in idle state, make engine run with preset low power interval;At the same time, drive the engine to drive the generator to continuously output
electric energy, charge the
energy storage circuit;When the unmanned aerial vehicle reaches the out-of-box time, make the engine speed smoothly rise to the preset
target engagement speed interval;When the engine speed is in the
target engagement speed interval, make the engine and the
propeller shaft power connection, realize
clutch engagement;In the
clutch engagement process, switch the
energy storage circuit from charging mode to discharging mode;After the
clutch engagement is completed, switch the
energy storage circuit from discharging mode to charging mode.The application realizes high reliability starting control of cruising unmanned aerial vehicle in box launching scene, significantly improves the task success rate and operation stability of the
system under complex working conditions.
