FIELD: test equipment.
SUBSTANCE: invention relates to closed type wind tunnels and can be used for carrying out of various tests of aircraft models, ground transport, buildings, structures, bridges. Device includes antechamber, collector, open working part, diffuser with length L with through damping holes with total area of 0.4-0.5 of collector outlet section area S with arrangement of holes rows at a distance from 0.6-0.9 of collector diameter D to L/3 of diffuser length from its inlet section, circular funnel above diffuser, rotary sections with rotary blades, return channel, blade fan, arranged behind diffuser. At that, diffuser has built-in damping holes shutter mechanism.
EFFECT: technical result consists in simplification of control by set of pulsating flow parameters in wind tunnel.
