Problems solved by technology

The shear pins are cut off after the ejection acceleration phase, losing kinetic energy of the aircraft and cannot be reused, nor can they lock the drone before ejection
The current inertia solution of the heavy hammer has a slow inertia release response, and the heavy hammer itself often has no buffer function during the deceleration section and is easily damaged
The support frame does not have the avoidance function of the ejection path, and has poor adaptability to UAVs with a double tail support structure

Abstract

The invention provides a UAV ejection lock release device and method, which relates to the technical field of UAV launch and recovery. It can realize the locking of the UAV on the ejection pulley before ejection and the automatic unlocking of the acceleration section after ejection, and has a support The ejection path avoidance function of the frame is reliable in structure and simple to use; the device includes a support frame, which is used to fix the locking release mechanism and is connected with the support frame tilting device to realize the tipping action of the UAV after ejection; the ejection hook is set On the belly of the UAV, it is used to connect the UAV with the latch release mechanism; the latch release mechanism is used to lock and unlock the UAV by locking and unlocking the ejection hook; the support frame tilting device is used to Install the support frame so that the support frame can be tilted down after the drone is ejected. The technical solution provided by the present invention is suitable for the process of ejection of a drone.

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...
