Description<\/strong><\/p>\n\n\n\n

The bench serves to study and try out processes of interaction of low-pressure single- and two-phase flows with aerofoils, grates, and other objects. Low-pressure air is delivered by a controlled-delivery fan into a pipeline connected to the fan by an elastic spacer. The exit of the pipeline is connected to a work chamber mounted on a rail-guided cart.<\/p>\n\n\n\n
