Novel fixed-wing unmanned aerial vehicle skyhook recovery mechanism and recovery method

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a novel fixed-wing unmanned aerial vehicle skyhook recovery mechanism and recovery method. The fixed-wing unmanned aerial vehicle skyhook recovery mechanism comprises a ground support and a rope assembly, wherein the ground support comprises a lower transverse arm folding mechanism, a main arm stretchable mechanism, an upper cross arm stretchable mechanism, an upper transverse arm folding mechanism and a chassis rotating mechanism; and the rope assembly comprises a plurality of pulleys, an upper buffer rope, a lower buffer rope and a recovery rope. According to the technical scheme, the skyhook recovery mechanism can be unfolded to a high degree of automation, and the rope assembly does not need to be installed on site.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a novel fixed-wing unmanned aerial vehicle skyhook recovery mechanism and recovery method. It can be fixed on the trailer chassis, car chassis, or on the fixed ground for the skyhook recovery of a certain type of fixed-wing UAV in a complex land environment; it can also be fixed on the deck of a ship for a certain type of fixed-wing UAV in the complex land environment. Skyhook Recovery in the Marine Environment. Background technique [0002] UAV is one of the modern high-tech equipment, which is widely used in military operations such as reconnaissance and strike. The UAV skyhook has strong environmental adaptability and can realize non-destructive fixed-point recovery, especially suitable for the recovery of small and medium-sized fixed-wing UAVs. [0003] The main function of the skyhook recovery mechanism is to use its ground support to tension t...

AI Technical Summary

Problems solved by technology

[0004] Most of the main arm of the current fixed-wing UAV skyhook recovery mechanism adopts a parallelogram linkage mechanism, which cannot support the skyhook mechanism high enough, and it is difficult to recover UAVs with large wingspan; the upper and lower cross arms are divided into two parts. The integrated method uses manual installation, which requires a large number of installers and takes a long time, which cannot meet the requirements of rapid deployment and recovery of UAVs; in some skyhook mechanisms, the rope components need to be installed on site, which requires high professional skills for operators.
