Description

Technical Field

[0001] This utility model relates to aircraft, and more particularly to a novel anti-collision and anti-fall rotorcraft. Background Technology

[0002] Existing rotorcraft, with their exposed rotors, are easily damaged upon collision with or impact with other objects. Furthermore, when the rotors stop or stall, existing rotorcraft plummet rapidly, posing a risk of injury to personnel or damage to property. Additionally, existing rotorcraft require landing gear and a flat surface for takeoff and landing, and cannot operate on water. Therefore, developing a novel collision- and crash-resistant rotorcraft has become a pressing issue for those skilled in the art. Summary of the Invention

[0003] The present invention addresses the aforementioned shortcomings by providing a novel anti-collision and anti-fall rotorcraft.

[0004] The above-mentioned objective of this utility model is achieved through the following technical solution: a novel anti-collision and anti-fall rotorcraft, comprising an aircraft body, the aircraft body comprising a fuselage, a connecting shaft and a rotor, the aircraft body being covered by a protective airbag, the protective airbag being provided with a fuselage duct and a rotor duct, the fuselage being located in the fuselage duct, and the rotor being located in the rotor duct.

[0005] Furthermore, the highest point of the fuselage and rotor is lower than the upper surface of the protective airbag, and the lowest point of the fuselage and rotor is higher than the lower surface of the protective airbag, that is, the fuselage and rotor as a whole are respectively recessed into the fuselage duct and rotor duct.

[0006] Furthermore, the protective airbag includes an upper airbag and a lower airbag, and both the upper airbag and the lower airbag have air chambers inside.

[0007] Furthermore, the upper and lower airbags are connected by Velcro, adhesive tape, cable ties, or buckles.

[0008] Furthermore, the inner side of the upper and lower airbags is provided with a groove for adapting the connecting shaft.

[0009] Furthermore, the openings of the rotor duct or fuselage duct are equipped with protective nets for enhanced safety.

[0010] The advantages of this utility model compared with the prior art are:

[0011] 1. This utility model isolates the rotor by surrounding the aircraft with multiple airbags, which can reduce the damage to the aircraft caused by collisions and reduce injury to personnel and damage to objects when a collision occurs.

[0012] 2. This utility model reduces the weight of the aircraft by replacing some structural components (such as brackets, guardrails, and frame shells) with airbags filled with lightweight gas, thereby increasing the effective payload or reducing flight energy consumption.

[0013] 3. This utility model can take off and land on uneven ground, as well as on water, effectively preventing the aircraft from falling into the water and being damaged.

[0014] 4. This utility model suppresses rotor noise by enclosing the rotor in the duct of the airbag, thereby reducing noise pollution of the aircraft.

[0015] 5. The buoyancy provided by the airbag of this invention can reduce the descent speed of the aircraft when the rotor fails, thereby improving safety. Attached Figure Description
