Problems solved by technology

Although the helicopter can go up and down directly, it only has one propeller, so the safety factor is low
The general aircraft lift needs a fixed special site, so its use is also subject to certain restrictions.

Embodiment Construction

[0024] Such as figure 1 , 2, 3, and 4. Described rotorcraft comprises fuselage 6, empennage 9, tail 8 and the propeller propeller 7 positioned at fuselage afterbody, is fixed with two rotors 13 above the fuselage, each rotor 13's left, There is a cylindrical propeller 4 inside each right side, the shaft of the propeller 4 is connected with the engine 10 located at the back of the fuselage through a coupling 11, and an airflow port is opened at the front edge of the rotor wing 13, and the airflow port is sealed. The upper end of the cover is hinged on the secondary wing 3 on the rotor wing 13, which is used to control the access to the propeller.

[0025] The working principle of the above-mentioned rotary-wing aircraft is as follows:

[0026] After the engine engine 10 is started, it is driven by the coupling 11 to drive the cylindrical propeller impeller 4 to rotate, so that the air is sucked into the rotor 13 and lifted up so that the air pressure is higher than the rear e...

Abstract

An airplane with rotary wings is composed of fuselage, tail wings, tail rudder, propeller at its tail and two rotary wings fixed to the top of fuselage. It features that each rotary wing has the left and right propellers, whose axle is linked to engine via coupler, and a secondary fin in the front of rotary wing for controlling the airflow coming in the propeller. Its advantages are vertical lifting or landing and high safety.

Description

technical field [0001] The invention relates to a rotary wing aircraft. Background technique [0002] Existing aircraft mainly contains helicopter and fixed-wing aircraft. Although the helicopter can go up and down directly, it only has one propeller, so the safety factor is low. And the lifting of general aircraft needs fixed special site, so its use is also subject to certain restrictions. Contents of the invention [0003] The object of the present invention is to provide an aircraft that can be directly lifted and lowered without a fixed special site, and has a high safety factor. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: the rotorcraft includes a fuselage 6, an empennage 9, a tail rudder 8 and a propeller propeller 7 positioned at the tail of the fuselage, and is characterized in that: Two rotor wings 13 are fixed on the top, and each rotor wing 13 has a cylindrical propeller 4 inside the left and...
