Aircraft with replaceable protective cover

Abstract

The invention discloses an aircraft with a replaceable protective cover. The aircraft comprises an aircraft body, the aircraft body is provided with a duct, and the duct is internally provided with an airscrew, wherein a plurality of clamping grooves are arranged between the end face and the inner wall of the duct, and a plurality of clamping keys are matched on the outer edge of a round cover body; each clamping key is matched and embedded into the clamping groove. Compared with the prior art, the aircraft with the replaceable protective cover effectively solves the problem of lack of a firm-structure protective cover capable of being conveniently replaced in the prior art, the round cover body is fixed through the clamping groove between the duct and the aircraft body, the round cover body is dismantled only by rotating while the airscrew in the duct is protected, and the operation is quite convenient.

Description

technical field [0001] The invention discloses an aircraft, in particular to an aircraft with a replaceable protective cover. Background technique [0002] The protective net of the aircraft is mainly used to protect the propeller. During the operation, it can avoid the damage to personnel caused by high-speed rotation, so the protective net is very important. [0003] Some unmanned aerial vehicles in the prior art do not have any protective measures for the flying propellers, which cannot provide effective protection for the safety of flight. [0004] Application number: 201010220017.X's invention application discloses a small electric ducted propeller intelligent unmanned aerial vehicle. The aircraft is composed of a duct enclosure, a bracket, a coaxial counter-rotating propeller, a fairing, a battery, an electric motor, a drive control circuit and a microcontroller. The appearance of the body is dish-shaped, and a duct enclosure is added outside the rotor, which elimina...

AI Technical Summary

Problems solved by technology

Its specific disclosed structure does not include protective measures, which may cause damage to the propeller when encountering special conditions during flight

[0005] Even for some UAVs with protective nets, by adding incomplete fan-shaped propeller lower protective nets, they all adopt an integrated design with the arm, which is not easy to replace

[0006] The other part of the aircraft protective net is mostly integrated with the fuselage or fixed by bonding. Once damaged in flight, it will be difficult to repair

Moreover, the flight protection net has a great influence on the airflow, and the use of the adhesive protection net cannot be conveniently selected and replaced according to the use situation or shape requirements

[0007] Therefore, there is a lack of a protective cover that can effectively protect the blades in the duct of the aircraft and is convenient for replacement in the prior art.
