Abstract

The invention discloses a vehicle-umbrella separating mechanism for initiating explosive release. The mechanism is mainly applied to vehicle-umbrella separating in the recovery process of a fixed-wing unmanned aerial vehicle. A piston in a cavity can be pushed to act through the chemical energy produced by explosion of an initiating explosive device, a limiting aluminum wire is cut off, a steel ball is released, and disengagement and separation of two connectors are achieved. The vehicle-umbrella separating mechanism of the unmanned aerial vehicle has the advantages of being small in size, simple in control mode and high in reliability.

Description

technical field [0001] The present invention relates to an executive mechanism of an unmanned aerial vehicle, specifically an umbrella separation mechanism released by pyrotechnics, which mainly applies the separation of the umbrella during the recovery process of the fixed-wing unmanned aerial vehicle, and controls the unmanned aerial vehicle manually or by sensors The parachute is separated. Background technique [0002] The parachute recovery system has been used on target drones and some UAVs for a long time. The general disadvantage of parachute recovery is that it is difficult to control the direction after the parachute is opened. Where a drone lands with a parachute, variable surface winds or high terrain can drag the aircraft along the ground, causing damage. Therefore, the current method is to separate the parachute once the plane lands to ensure the safety of the plane after landing, so a parachute separation mechanism is very necessary for the parachute recovery...
