Description

【Technical field】

[0001] The invention relates to the technical field of unmanned aerial vehicle launch and recovery, and in particular to an unmanned aerial vehicle ejection locking release device and method. 【Background technique】

[0002] Military drones are advanced combat equipment with high technological content. UAVs that use catapults to take off do not need a runway, and can be launched within a length of 10 meters that can be deployed by the catapult. The launch cost is low and the launch time is short. It is especially suitable for the rapid launch of small and medium-sized fixed-wing UAVs.

[0003] At present, there are mainly several types of catapults for UAVs, such as pneumatic ejection, motor ejection, and electromagnetic ejection. They are essentially an energy conversion device, which converts the potential energy stored in the catapult or external electrical energy into the take-off of the UAV in a short time. kinetic energy.

[0004] Commonly used catap...
