Problems solved by technology

[0002] Current aircraft, especially helicopters, use axial flow fans, i.e. rotors, to provide lift. Axial flow fans have a low power factor, which only reaches about 40% of their effective power, poor flight performance, and large rotor diameters; If the rotating speed is too high, a vacuum will be generated at the tip of the wing, causing its efficiency to drop sharply; as a rotor for a helicopter, a complex mechanism is required to control the movement of the rotor, which has high cost and low reliability; because the rotor can only be set On the top of the fuselage, the ejection life-saving device cannot be installed. In case of emergency, the living space of the crew is small. At the same time, it is greatly affected by the external weather conditions.
With the expansion of the use of helicopters, the use conditions are more complicated and harsh, and the axial-flow rotors are no longer suitable for the vertical take-off and landing of aircraft.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] Among Fig. 1, the centrifugal fan 3 is located at the front of the fuselage, and the motor 6 is connected with the centrifugal fan 3 or connected with the motor through a transmission mechanism. In front of the centrifugal fan 3, an air inlet 1 and a fairing 2 are arranged, and the centrifugal fan The periphery of 3 is provided with air outlet 5 and wind deflector 4, and the rear of fuselage 7 is provided with empennage 8, and aircraft becomes vertical state after landing and take-off, when engine 6 drives centrifugal fan 3 to rotate, air can pass through Centrifugal fan 3 produces dynamic pressure energy and escapes into the atmosphere from the air outlet at a high speed, and produces a reaction force to make the aircraft rise. Manipulating the empennage 8 makes the aircraft tilt or become horizontal, and the aircraft can fly forward. The empennage 8 can be used as a...

Abstract

The aircraft with centrifugal fan for vertically taking off and landing has one centrifugal fan set in the front part or upper part. The centrifugal fan is driven with the engine to produce air work medium with dynamic pressure energy to push the aircraft to take off or land vertically, to hover or to fly forward.
