External parachute pack for fixed-wing unmanned aerial vehicle

Abstract

The invention discloses an external parachute pack for a fixed-wing unmanned aerial vehicle, and relates to the field of unmanned aerial vehicle safety devices; the external parachute pack comprises abottom shell; a fairing is mounted at the top end of the bottom shell in a matched mode, a cavity is formed between the fairing and the bottom shell, and a safety parachute, a cylinder and a servo steering engine are mounted in the cavity; an opening of a circular groove of the cylinder is vertically upward, the bottom ends of the cylinder and the servo steering engine are fixedly connected withthe bottom shell, a piston and a spring are slidably sleeved in the circular groove of the cylinder, the piston is located at the top end of the spring, a circular hole is formed in the circumferential side wall of the piston in the radial direction, and a bayonet lock is sleeved with the circular hole in a matched mode. The external parachute pack is novel in structure, simple in structure, convenient to operate, safe and reliable, and the problem that the fixed-wing unmanned aerial vehicle lacks self-rescue capacity when encountering a forced landing danger is effectively solved.

Description

technical field [0001] The invention relates to the field of safety devices for unmanned aerial vehicles, in particular to an external umbrella bag for fixed-wing unmanned aerial vehicles. Background technique [0002] UAV is an efficient and safe flying device, which plays an important role in both military and civilian fields, but the safety of UAV is only relative to unmanned driving. With the current UAV technology, In the process of fully autonomous flight of the UAV, the perception, judgment and reaction ability of the flight environment are lower than those of the pilot, especially the ability to respond to emergencies. How to make a forced landing to recover the losses as much as possible is very important. [0003] There are mainly two types of existing drones, one is a multi-rotor aircraft, and the other is a fixed-wing aircraft. The common fall prevention of drones on the market is in the form of a parachute bag, but it is mostly used for rotor aircraft. The sha...
