Unmanned aircraft and protecting method thereof

Abstract

The invention discloses an unmanned aircraft and a protecting method thereof. The unmanned aircraft comprises a fuselage and a gas bag. The gas bag is arranged above the fuselage. When the unmanned aircraft starts to fall or is about to fall, the gas of which light is lighter than that of air is inflated into the gas bag to make to gas bag to swell.

Description

technical field [0001] The invention relates to an aircraft and a protection method thereof. More specifically, the present invention relates to an unmanned aerial vehicle and a method of protecting it. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. [0003] From a technical point of view, unmanned aerial vehicles can be divided into: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, unmanned paraplanes, etc. [0004] For example, the Chinese patent: "Agricultural Unmanned Helicopter" (patent application number: 201410572827.X) discloses an unmanned helicopter. Unmanned helicopters are simple in structure, low in price, can take off and land vertically, and can also complete some complex flight actions. [0005] Another example is the Chinese patent: "A Fixed-wing UAV Altitude Control System" (patent application number: CN20...

AI Technical Summary

Problems solved by technology

[0020] The first reason is that parachutes have a certain weight. For small, medium and micro unmanned aerial vehicles that are light in weight, not strong enough in power, and generally capable of endurance, the installation of parachutes will have a fundamental impact on the flight performance of unmanned aerial vehicles. Thereby affecting the flight speed of the unmanned aerial vehicle and the execution of flight maneuvers

[0021] The second reason is that the opening time of the parachute is long and the deceleration is slow. For a crash at medium and low altitudes, the parachute does not have time to open at all, and it is too late to take effect. Aircraft provide flight protection

Therefore, it is impossible to avoid the occurrence of a crash for a crash at a low altitude.

[0022] The third reason is that parachutes are expensive and difficult to recycle. For consumer-grade unmanned aerial vehicles, it greatly increases the cost and is troublesome to use, which greatly affects the user experience and causes damage to users. bad impression

[0027] However, none of the above methods can fundamentally solve the problem of avoiding damage when the unmanned aerial vehicle crashes due to an accident.
