Problems solved by technology

It is the technical problem of low working efficiency of the existing fan itself, which leads to the fact that the vertical take-off and landing effect of the aircraft equipped with this kind of lift fan cannot be compared with the roll take-off

Embodiment Construction

[0021] The multi-stage powerful fan of the present invention has a specific realization structure as shown in the accompanying drawings. It is composed of two-stage, three-stage or more concentric fan rings extending from the center to the outside. This embodiment adopts four-stage fan rings. The structure of the fan rings 41, 42, 43, 44, taking the fan ring 42 of the first stage as an example, the ring gear 1 of each stage is rotated and assembled with the corresponding fan ring outer frame ring 3 through the rotating bearing, and is arranged on the ring gear 1 On the top, a number of fan blades 2 are arranged uniformly and radially to the circumference with the common central center as the rotation center. The ring gear 1 is used as a follower to mesh with the tooth-shaped part 4 that transmits the same rotational power, and drives the fan blades of the fan ring to rotate. work, such as image 3 As shown, each outer frame ring 3 is fixed on the upper connecting crossbeam 7 t...

Abstract

The invention relates to a multi-stage powerful fan and a vertical takeoff and landing aircraft. The multi-stage powerful fan provided by the invention is composed of multiple stages of concentric fan rings which extend from the center to the outside, wherein a gear ring is arranged on the outer rack ring of each stage of fan ring in a rotating manner, a plurality of fan blades use the common extension center as the center of rotation and are arranged on the gear ring uniformly and radially; and the gear ring is a follower which is in mesh transmission with a jugged part which transmits the same rotation power. The technical scheme of the invention realizes the technical aim of increasing the wind power conversion efficiency of the entire fan and has wide range of application. The vertical takeoff and landing aircraft provided by the invention utilizes the powerful lifting force generated by the multi-stage powerful fan for driving, thus the vertical takeoff and landing of the aircraft can be realized; and the multi-stage powerful fan has simple structure and light weight, can be used as a part of the airfoil surface and can not affect the normal flight of the aircraft.

Description

technical field [0001] The patent application of the present invention relates to the improvement of fan technology and the application of the improved fan to realize vertical take-off and landing aircraft. Background technique [0002] It is people's biggest dream after owning helicopters and airplanes to make an airplane that can only taxi horizontally take off possess ideal vertical takeoff and landing functions. The earlier aircraft that can take off and land vertically are more typical of the Harrier aircraft from the United Kingdom and the Yak 38 / 41 aircraft from Russia. The British Harrier uses a dedicated jet engine and a steerable nozzle structure, while the Russian Yak 38 / 41 uses a dedicated lift jet engine. The engine works with high-speed jet, and the jet thrust is used to counter the gravity of the aircraft to achieve vertical take-off and landing. This type of aircraft faces the main problems of insufficient load capacity, too short combat radius, relatively c...
