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 an unmanned aerial vehicle launch shutting and releasing device and method, and relates to the technical field of unmanned aerial vehicle launch recovery. The unmanned aerial vehicle launch shutting and releasing device can realize the locking of the unmanned aerial vehicle on a launch pulley before launch and automatic unlocking in the acceleration segment after launch, theunmanned aerial vehicle launch shutting and releasing device has an avoidance function of a supporting frame to the launch path, the structure is reliable, and the use is simple; the unmanned aerialvehicle launch shutting and releasing device comprises the supporting frame, a launch hook and a shutting and releasing mechanism and a supporting frame toppling device, the supporting frame is used for fixing the shutting and releasing mechanism and is connected with the supporting frame toppling device to realize the toppling action after the unmanned aerial vehicle is launched, the launch hookis arranged on the abdomen of the unmanned aerial vehicle and is used for connecting the unmanned aerial vehicle with the shutting and releasing mechanism, the shutting and releasing mechanism is usedfor locking and unlocking the unmanned aerial vehicle through locking and unlocking the launch hook, and the supporting frame toppling device is used for installing the supporting frame to enable thesupporting frame to realize the toppling action after the unmanned aerial vehicle is launched. According to the technical scheme, the unmanned aerial vehicle launch shutting and releasing device andmethod are applicable to the launch process of the unmanned aerial vehicle.

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...
