Embodiment Construction

[0030] Such as figure 1 and figure 2 As shown, the rotor-type unmanned aerial vehicle fall protection device of the present embodiment includes: a chassis 1, a combustion chamber 2 installed on the chassis 1 and an ignition device 3, and symmetrically arranged catapults are respectively installed on both sides of the top of the combustion chamber 2 4. The two catapults 4 are symmetrically arranged and inclined to both sides with an inclination angle of 45 degrees; each catapult 4 is equipped with a parachute 5, and each parachute 5 is connected with three parachute ropes 51, and the ends of the parachute ropes 51 are fixed On chassis 1. The ignition device 3 is controlled by an electronic control module 6 also mounted on the chassis.

[0031] In order to prevent the gunpowder 21 from burning the umbrella surface of the parachute 5 and ensure that the combustion chamber 2 is as airtight as possible, in this embodiment, the catapult 4 is filled with flame-retardant fibers 7 b...

Abstract

The invention discloses a protection device for an out-of-control crash of a rotary-wing-type unmanned aerial vehicle. The protection device comprises a base plate and an ejection mechanism installed on the base plate. The ejection mechanism comprises a combustion chamber fixed to the base plate, at least two ejection guns with the bottoms communicated with the combustion chamber, parachutes installed in the ejection guns and an ignition device, wherein all the ejection guns are annularly and evenly distributed and incline and extend outwards. The invention further discloses the rotary-wing-type unmanned aerial vehicle and a protection method for the out-of-control crash of the unmanned aerial vehicle, wherein the protection device for the out-of-control crash of the rotary-wing-type unmanned aerial vehicle is adopted in the protection method. According to the protection device, due to the fact that the ejection guns are arranged and annularly and evenly distributed and incline and extend outwards, the amount of gunpowder is reduced, damage to the unmanned aerial vehicle during explosion is alleviated, impact of a part of reactive force on the unmanned aerial vehicle is offset, and damage, caused by ejection of the gunpowder, to the unmanned aerial vehicle is further alleviated.

Description

technical field [0001] The invention relates to aviation flight equipment, in particular to an uncontrolled fall protection device and protection method for a rotor-type unmanned aerial vehicle. Background technique [0002] At present, small drones at home and abroad have been widely used in civilian and military fields, such as disaster monitoring in disaster areas, aerial photography of TV stations, power line inspection, weather detection, target detection, etc. During the flight of a small UAV, any abnormality of any part or link may cause the aircraft to lose control and crash, thereby causing damage to the airframe itself and onboard equipment. Philippines, once a crash occurs, it will cause huge property value. [0003] In order to reduce the loss of the UAV in the event of an accident, in addition to using the above-mentioned technologies to improve the flight reliability of the UAV, it is necessary to increase the protection and recovery equipment for the UAV and ...
