Launching tube

Abstract

The invention discloses a launching tube. The launching tube comprises a tube body, a bottom cover, a piston and a pull rope; the bottom cover is mounted at the tail end of the tube body and seals a port at the tail end; the piston is mounted within the tube body; the piston is kept in dynamical seal with the tube body; a sealed power launching silo is formed among the piston, the tube body and the bottom cover; the power launching silo is used for mounting an initiating explosive device; one end of the pull rope is connected with the piston; the other end of the pull rope is connected with the bottom cover; and the total length of the pull rope is slightly larger than that of the launching tube. The launching tube is used for launching folding ring unmanned aerial vehicles; the folded unmanned aerial vehicle is plugged into the tube body from the front end of the tube body; after the initiating explosive device is ignited, high pressure gas generated within the power launching silo pushes the piston and the unmanned aerial vehicle to move in the tube body in an accelerated manner; and after the piston and the unmanned aerial vehicle leaves away from the tube body, the piston is limited by the pull rope and the unmanned aerial vehicle is immediately separated from the piston near the port of the front end of the tube body; and therefore, the piston is prevented from affecting the normal unfolding of wings of the unmanned aerial vehicle and the normal starting of a power device and the launching stability of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle launch equipment, in particular to a launch tube for unmanned aerial vehicle launch. Background technique [0002] Unmanned aerial vehicles refer to unmanned unmanned aircrafts, which are generally controlled by airborne programs or ground remote control facilities. The characteristics of small size and no fear of danger make drones have a very wide range of uses in both military and civilian fields, such as aerial photography, plant protection, disaster relief, exploration and anti-terrorism. Different application fields have different working environments. In order to adapt to complex working environments, the prior art UAVs have developed a variety of launch methods, such as runway launch, rocket-assisted launch, orbital catapult launch, Motherboard air launch and barrel launch, etc. Among them, the barrel launch is mainly used in folding wing drones. The launch tube stores the folded d...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that in the process of using the UAV launch tube in the prior art, it is easy to produce phenomena such as the wings cannot be deployed normally and the attitude of the tube is abnormal, which affects the success rate of the UAV launch.
