Double-winglet annular lift wing device for pneumatic aerotrain

Abstract

The invention discloses a double-winglet annular lift wing device for a pneumatic aerotrain, and relates to the technical field of lift devices for pneumatic aerotrains. The double-winglet annular lift wing device comprises a pneumatic aerotrain body and further comprises side wings, winglets, pressure maintaining winglets, ground-effect wings and upper-layer wings, the upper-layer wings are arranged on the two sides of the upper end of the pneumatic aerotrain body, and the ground-effect wings are arranged on the two sides of the lower end of the pneumatic aerotrain body. A double-layer wing structure is adopted, the wingspan length is reduced on the basis of a single wing, meanwhile, the lift force effect is improved, the occupied area of track construction is greatly reduced, meanwhile, due to the fact that the wingspan is reduced, the structural strength is improved, a sufficient centripetal force is provided during steering through design, and after driving out of the curve, the two sides quickly return to the center due to the pressure difference due to the disappearance of centripetal force and automatically keep driving in the center of the track.

Description

technical field [0001] The invention relates to the technical field of lift devices for aerodynamic suspension trains, in particular to an annular lift wing device with double winglets for aerodynamic suspension trains. Background technique [0002] The ground effect aircraft is a kind of aircraft that uses the ground effect. The so-called ground effect is a kind of hydrodynamic effect that reduces the induced resistance of the aircraft and can obtain a higher lift-to-drag ratio than flying in the air. The traditional ground effect aircraft is mostly on water. Aircraft, this kind of ground effect aircraft often has the characteristics of large wingspan length, and also has the following disadvantages: [0003] 1. The large span of the aircraft will occupy a large amount of land resources, and at the same time result in low structural strength; [0004] 2. The large centripetal force cannot be achieved when the aircraft turns, resulting in unstable driving; [0005] 3. When...

AI Technical Summary

Problems solved by technology

[0008] The object of the present invention is to provide a ring-shaped lifting wing device with double winglets for aerodynamic suspension trains to solve the existing problems: when a multi-wall coupled ground effect aerodynamic suspension train adopts a single-layer lift wing, the floor area is large and the heading is low. The stability is poor, and the energy loss of the tip vortex of the double-layer wing is large
