Deceleration separation device

Abstract

The invention discloses a deceleration separation device which comprises a deceleration parachute cabin, a combination actuator, a deceleration parachute pack, a battery box and a sub-machine controlpanel. The deceleration parachute bay comprises a parachute bay body and a parachute bay cover; a first port of the parachute bay body is clamped with the parachute bay cover; a second port of the parachute bay body is connected with a sub-aircraft protection cylinder of the unmanned aerial vehicle through a first connecting part; the assembling actuator is fixedly arranged in the parachute bay body; one end of the combined actuator is a parachute throwing device and is connected with the parachute cabin cover; the other end of the combined actuator is an explosive bolt and is connected with atransition joint of the unmanned aerial vehicle; the deceleration parachute pack is arranged in the deceleration parachute cabin and connected with the parachute cabin cover and the assembling actuator through second connecting parts. The battery box is arranged in the parachute bay body and is respectively connected with the parachute throwing device and the explosive bolt; and the sub-machine control panel is arranged in the parachute bay body and is in communication connection with the parachute throwing device and the explosive bolt respectively. The device can be separated from the aircraft, the weight during free flight is reduced, and the cruising ability of the aircraft is improved.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to a deceleration and separation device. Background technique [0002] At present, most recovery deceleration devices for unmanned aerial vehicles are modular single devices such as first-level drogue parachute devices or rear speed brakes. The interference of leaves, and the rear speed brake is likely to cause additional torque when decelerating, and the deceleration effect is not good. In addition, the existing reduction gears do not involve a separation device. Contents of the invention [0003] The purpose of this application is to provide a deceleration separation device, which can effectively separate from the aircraft after realizing the deceleration function, reduce the weight of the aircraft when it is flying freely, and improve the endurance of the aircraft. [0004] In order to achieve the above purpose, the application provides a decelerati...
