ABSTRACT:
The wind tunnel for testing a transport vehicle comprises rotary drums mounted on a base with their bearing surfaces located in the working chamber of the wind tunnel, essentially level with its floor, and a wind tunnel balance located in the zone of the rotary drums and comprising a frame which is linked mechanically with dynamometers secured to the base and a supporting platform. The frame is located at the outer sides of the rotary drums, somewhat below their bearing surfaces so that said rotary drums are inside said frame, and is connected with at least three horizontal links whose ends are articulated with the base via vertical links of which one is directed up and the other down. The supporting platform is located in the working chamber of the wind tunnel and mounted on the frame so that it can turn around a vertical axis during the test of the transport vehicle on the wind tunnel balance and be removed during the test of the transport vehicle on the rotary drums. This design of the wind tunnel is characterized by the comparatively small length of the working chamber.
