Problems solved by technology

In addition, in order to reduce air resistance, the high-speed train research and development enterprises represented by the US Hyperloop Corporation allow the transportation vehicles to run in pipes that are similar to vacuum, and even install a powerful suction fan at the front end of the transportation vehicles to suck the air in the pipes. gas to reduce resistance, this scheme is in the stage of theoretical and experimental verification, and its practical feasibility and economic benefits are yet to be verified

Embodiment Construction

[0024] An air guide device and method for reducing air pressure differential resistance when a high-speed moving body moves, such as figure 1 As shown, the ventilation duct 104 is arranged on the surface close to the high-speed moving body, along the direction of motion, the air inlet of the pipeline is positioned at the front end (head 104) of the high-speed moving body, and the air outlet is positioned at the rear end (tail portion 103) of the high-speed moving body .

[0025] Concrete device and method are as follows:

[0026] air guide as figure 1 As shown, the high-speed moving body in the air includes a head 101 , a middle 102 and a tail 103 . A guide channel (ventilation duct 104) is arranged on the top of the moving body. When the moving body moves at a high speed in the air, the head air 105 is squeezed into the diversion channel, and the extruded gas diffuses at the tail through the diversion channel to fill the tail vacuum area caused by the extrusion of the movi...

Abstract

The invention discloses an air guide device and a method for reducing the air pressure drag through the air guide device. The device comprises a ventilation pipeline with the size and shape adjustable. The ventilation pipeline is provided with an air inlet and an air outlet. The method includes the steps that the ventilation pipeline is arranged tightly attached to the surface of a high-speed motion body, in the motion direction, the air inlet of the pipeline is located at the front end of the high-speed motion body, and the air outlet of the pipeline is located at the rear end of the high-speed motion body. Compared with the prior art, the device and method are suitable for an object, such as a high-railway train and a high-speed automobile moving in the air at a high speed, air of the windward face of the motion body is guided to the leeward face of a vehicle, so that the air pressure difference of the windward face and the leeward face of the motion body is reduced, the pressure drag is reduced, and the device and method have wide application prospects in the aspects of transportation, energy conservation and environment protection.

Description

technical field [0001] The invention relates to a method for reducing air pressure differential resistance, in particular to an air guiding device and a method for reducing air pressure differential resistance by using it. Background technique [0002] With the continuous advancement of science and technology, rapid transportation represented by high-speed trains and private cars has greatly improved people's travel convenience and timeliness. However, as the speed of the high-speed moving body in the air continues to increase, the air resistance it receives increases in a geometric exponential form, which sets obstacles for further increasing the speed of the moving body. In order to achieve higher speeds, greater energy consumption must be expended. [0003] Taking a high-speed train as an example, the running resistance of the train is composed of three parts: mechanical resistance, wheel-rail resistance, and air resistance. There are three kinds of train air resistance...
