Embodiment Construction

[0014] like figure 1 , figure 2 As shown, the fairing 1 of the head car of the motor vehicle is made as a duckbill-shaped streamlined body that is horizontally flat, has a flush front end, a large upper arc, and a small lower arc, and straight sides. The deflector 2 is a longitudinally vertical flat plate, which blocks both sides of the fairing 1 and extends outward, and the extended part is gradually narrowed at the front and narrow at the rear.

[0015] Except for the technical features described in the description, all are known technologies by those skilled in the art.

Abstract

The invention provides a longitudinal two-way flow guide type bullet train head which comprises a fairing and a flow guide plate, and is characterized in that the fairing is in a duckbilled streamline shape which has the characteristics that the front end is transversely flat, the longitudinal diameter of the front end is gradually increased from front to rear, an upper arc is large, a lower arc is small and two sides are flat; the flow guide plate is a longitudinal vertical flat plate which blocks the two sides of the fairing and extends outwards. Comparedwith the prior art, air in front of a bullet train during running of the bullet train is diverted upwards and downwards by the fairing and the flow guide plate, so that transverse flow and eddy flow caused by compressed air are limited at the top of the bullet train in open space and the bottom of the bullet train in fixed space, less disturbed air is generated on the two sides of the bullet train, and the transverse width of air stream is relatively small; the air stream diverted to the upper part of the bullet train is relatively easy to disperse due to the open space; the air stream diverted to the bottom of the bullet train difficultly forms the transverse flow due to the ground effect, so that the bullet train is slightly jolted; the relatively high-speed air stream is reduced on the two sides of the bullet train, so that the influence of nearby dynamic and static large-sized objects is reduced, the left-right swing is slight, the bullet train is relatively stable, the attractionto nearly dynamic and static small-sized objects is reduced, and the bullet train is relatively safe.

Description

1. Technical field [0001] The invention relates to a railway moving car, in particular to a flow locomotive with up and down bidirectional guidance. 2. Background technology [0002] With the improvement of the running speed of railway locomotives, it is an inevitable choice to adopt a streamlined design for trains. Bullet-shaped express trains and high-speed trains have become the basic model for the appearance of bullet trains. However, there are many differences in the external environmental factors of locomotives operating on railways and aircraft operating in the air, and it is impossible to obtain the same beneficial effect by adopting the same or similar shapes. The reason is the way the two overcome obstacles in the process of movement, and the difference between the influence of external factors and the influence of external factors: the aerial vehicle is in an all-round gas environment with relatively uniform density and high compression elasticity ratio during mo...
