Unmanned aerial vehicle rocket disengaging mechanism with rear-mounted power layout

Abstract

The invention discloses an unmanned aerial vehicle (UAV) rocket disengaging mechanism with a rear-mounted power layout. The unmanned aerial vehicle rocket disengaging mechanism is composed of a rocketthrust seat, a rocket booster, a disengaging frame assembly and a disengaging frame guider, wherein the front end portion of the disengaging frame assembly is connected to a UAV through the disengaging frame guider, and the rear end portion of the disengaging frame assembly is connected to the rocket booster through a buffer pin; when the UAV makes prelaunch preparatory work on a launcher, the rocket booster is mounted on the UAV through the rocket thrust seat, and the disengaging frame guider is rotated to rotate around the shaft by a certain angle, and the disengaging frame assembly is connected and mounted through a front fork of the disengaging frame; and after the rocket booster finishes working, after the rocket booster and the disengaging frame assembly are rotated around the disengaging frame guider to a certain angle, the disengaging frame assembly is separated from the disengaging frame guider to realize UAV launching. The UAV rocket disengaging mechanism with a rear-mountedpower layout is ground auxiliary equipment, can reduce the workload of ground cable mediation, and has the characteristics of simple structure, convenient maintenance and high reliability of UAV launching.

Description

Technical field [0001] The present invention relates to the technical field of unmanned aerial vehicles, and specifically to a rear-mounted powered layout unmanned aerial vehicle rocket shedding mechanism. Background technique [0002] At present, UAVs have been widely used in many fields such as battlefield reconnaissance and surveillance, precise target positioning, artillery correction shooting, laser irradiation guidance and damage effect assessment. Due to the low cost of UAVs, good penetration capabilities and outstanding performance in applications, UAVs with excellent performance are needed in many fields. Therefore, the safety, reliability, economy and applicability of UAVs are The biggest design challenge. [0003] Among the various take-off methods of UAVs, rocket-assisted zero-length launch is the most widely used. The principle is to use the thrust of the rocket booster to push the drone to a safe speed and altitude in a short period of time. At present, UAVs...

AI Technical Summary

Problems solved by technology

The former is prone to collisions between the rocket booster and the power unit of the UAV during the UAV launch phase, resulting in the failure of the UAV launch

The latter requires the UAV to adjust the length of the cable before each flight, and the ground operation is complicated

After the rocket booster is separated from the upper thrust seat of the UAV, it is connected by a soft cable, which can easily cause the rocket booster to be unable to separate from the UAV after launch.
