Abstract

The invention relates to a flexible bionic landing system and its application. The flexible bionic landing system includes a bionic flexible landing device and a connecting device connected above the bionic flexible landing device. The bionic flexible landing device is a flexible body; the connecting device It includes a hollow connection body and an air compression device communicating with the hollow part of the connection body. The flexible bionic landing system of the present invention has a simple structure, is easy to maintain, and has low production costs. It adopts a flexible structure design to absorb the vibration of the body of the drone when it lands on a complex surface, and at the same time improves the landing adhesion. The flexible bionic landing system of the present invention is adopted The UAV of the landing system can land in complex terrain environments such as large slopes and high wet slippery, realize landing in complex terrain and provide long-term monitoring and ground information support, reducing the need for UAVs to land on flat and small slopes. Limitations of location landings.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles and relates to unmanned aerial vehicle landing technology, in particular to a flexible bionic landing system and its application. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and its own program control device. It can be used for aerial reconnaissance, surveillance, communication, anti-submarine, electronic interference, etc. Power inspection, aerial photography and other fields, and play an important role. [0003] Due to the influence of environmental factors in the target area of ​​the UAV, the UAV cannot choose the landing point arbitrarily when it lands. In order to monitor the target area at close range, the UAV needs to select the landing point nearby in the target area. At present, When domestic and foreign drones land, they need to use ground signs to guide and assist in landing. However, due to the complex environm...
