Takeoff catapult acceleration mechanism of taxiing unmanned aerial vehicle

Abstract

The invention discloses a takeoff catapult acceleration mechanism of a taxiing unmanned aerial vehicle, and particularly relates to the field of unmanned aerial vehicles. The acceleration mechanism comprises a taxiing runway and a body, a locking release mechanism is fixedly mounted on the surface of the taxiing runway, ejection hooks are fixedly mounted at the bottoms of wings on the left and right sides of the body, and ejection ropes movably sleeve the surfaces of the ejection hooks; the other sides of the ejection ropes are fixedly connected with fixing ground nails, and the locking release mechanism comprises an operating lever locking frame, an operating lever, a bounce limiting support and a rear wheel blocking hook. When the unmanned aerial vehicle slides on the runway, the take-off safety is not high enough under the condition that the runway length is not long enough or the runway condition is not good and not long enough due to the fact that the sliding distance needed by sliding take-off of the unmanned aerial vehicle is increased, and at the moment, the take-off safety of the unmanned aerial vehicle is not high enough; however, with the safe take-off mechanism, the runway length required by taxiing and takeoff of the unmanned aerial vehicle is reduced, the requirement for the runway is lowered, and the taxiing and takeoff safety is improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle, more specifically, the invention is a take-off and ejection acceleration mechanism of a rolling unmanned aerial vehicle. Background technique [0002] With the development of science and technology and military equipment technology, the application of UAVs in the civilian field is also increasing, such as: land and resources investigation, emergency relief, deep forest fire monitoring, environmental monitoring, etc., and it is becoming a modern high-tech in the military field. Indispensable weapons in scientific and technological warfare are increasingly equipped with the land, sea and air forces of various countries, and are used to perform combat tasks such as attack and reconnaissance and training tasks for target drones.

AI Technical Summary

Problems solved by technology

[0003] In the existing plateau application scenarios, the taxiing distance required for UAV taxiing and take-off increases, resulting in insufficient runway length, or the condition of the runway itself is not good, and when the length is insufficient, the UAV will not be able to run on the runway. , the safety of take-off is not high enough. When the drone runs for a long time, the wheels at the bottom of the drone will have high-intensity friction with the runway, which will cause serious wear to the wheels and other devices.

[0004] In addition, when taking off, the existing UAVs use their own power or thrust to roll and take off. Due to the large kinetic energy of their own power and thrust, and when the engine and other devices are working, very large vibrations will be generated. The force will cause the body to vibrate, too much vibration will affect the take-off speed of the UAV, and seriously cause the UAV to fail to take off

[0005] Finally, when the existing UAV takes off and rolls, the UAV is deployed on the runway, and then the device such as the engine of the UAV is started to control the UAV to take off. When the UAV is deployed on the runway, due to the lack of a good locking and releasing mechanism, it is easy to move when the UAV is deployed, which leads to the deviation of the body, which seriously causes the UAV to deviate from the runway, resulting in Collision damage
