Abstract

The invention relates to a flexible bionic landing system and application thereof. The flexible bionic landing system comprises a bionic flexible landing device and a connecting device connected to the upper portion of the flexible landing device. The bionic flexible landing device is a flexible body. The connecting device comprises a hollow connecting body and an air compressing device communicating with a hollow part of the connecting body. The flexible bionic landing system is simple is structure, easy to maintain and low in production cost, and adopts a flexible structure design to absorb vehicle body shock generated when an unmanned aerial vehicle lands on complex earth surfaces and improve landing adhesive force; and the unmanned aerial vehicle adopting the flexible bionic landing system can land on the complex terrain environments such as a large-gradient terrain and a high-slipperiness terrain, landing on the complex terrains is achieved, long-time surveillance and earth surface information support are supplied, and the limitation that the unmanned aerial vehicle needs to land on flat and small-slope positions is reduced.

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...
