Small UAV canopy

Abstract

The invention discloses an umbrella hatch cover of a small unmanned aerial vehicle parachute recovery system. The umbrella canopy is composed of a front cover of the umbrella canopy and a rear cover of the umbrella canopy. The open double umbrella canopy makes the front and rear umbrella hanger joints all placed inside the fuselage, and the rear cover of the umbrella canopy uses a limit cloth to limit the opening angle and reduce the flight resistance. The split double umbrella canopy reduces the rigidity requirements for the umbrella canopy. The umbrella canopy is made of carbon fiber composite material with a honeycomb sandwich structure, which can reduce the weight by 60% compared with the aluminum alloy canopy canopy.

Description

Small unmanned aerial vehicle canopy canopy technical field The present invention relates to the canopy cover of a kind of small unmanned aerial vehicle parachute recovery system. Especially when it comes to parachuting small drones Split double umbrella hatch for recovery system. Background technique Parachute recovery is the commonly used recovery mode of small unmanned aerial vehicles. The recovery umbrella generally passes through the three umbrella belts and the three belts on the fuselage. There are two umbrella hanging joints, including two front hanging points and one rear hanging point.
