Unmanned aerial vehicle retractable type ski recovery device

Abstract

The invention discloses an unmanned aerial vehicle retractable type ski recovery device. The unmanned aerial vehicle retractable type ski recovery device comprises that a front shrinking cylinder is installed inside a belly of a machine body, the top end of a front shock absorber is fixedly installed at the bottom of the front shrinking cylinder and the bottom end of the shock absorber is installed on a front sliding block through a hanging lug and a connecting bolt, the front sliding block is installed in a guide groove of a front sliding seat, and the front sliding seat is installed on a front sliding seat base. An electromagnetic switch is installed on the bottom face of the belly of the machine body, and the electromagnetic switch is located right above a suction cup. A rear shrinkingcylinder is installed in a belly of the machine body, the top end of a rear shock absorber is fixedly installed at the bottom of the rear shirking cylinder and the bottom end of the rear shock absorber is installed on a rear sliding block through a hanging lug and a connecting bolt, and metal ploughs are installed on the outside of two sides of the rear end of a ski. The unmanned aerial vehicle retractable type ski recovery device is simple in structure and realizable in separation, and can obtain good landing buffering performance; a replaceable wear resistant layer is installed on the frontpart of the ski to effectively protect a ski body structure; and the metal ploughs are installed on the rear portion of the ski to play the role of stable guidance and deceleration.

Description

technical field [0001] The invention relates to the technical field of UAV landing, in particular to a UAV retractable skid recovery device. Background technique [0002] In the UAV system, the vast majority of UAVs take off by launching from the launcher, rolling off the take-off vehicle to help the flight, and launching the parent aircraft. There is no need to consider the need for "starting". Compared with the wheel system, the skid system has the following characteristics: (1) The retractable skid device has a simple structure, and the radar echo is very small, and it will not hinder the field of view of the effective reconnaissance load; (2) The skid and recovery The friction of the site can make the aircraft decelerate in a short time and distance until it comes to a complete stop, eliminating the need for auxiliary deceleration devices such as brake systems or other arresting equipment in the wheel recovery device; (3) the skid has no requirements for the recovery si...

AI Technical Summary

Problems solved by technology

[0003] The existing UAV recovery device has a complex structure, high cost, poor performance stability and reliability, which seriously affects the reconnaissance performance of the UAV during flight, and has a short service life, which increases the cost of using the UAV.
