FIELD: aerodynamics.
SUBSTANCE: invention relates to experimental aerodynamics and can be used in development of aerodynamic pipes and testing. Wind tunnel comprises ejector, which consists of three shafts, at least one of which comprises perforated nozzle. Ejector control system configured to include boreholes independently of each other comprises throttles and gates, the perforation in the ejector nozzle is made in the form of longitudinal slots.
EFFECT: technical result consists in reduction of high-pressure gas consumption at less stressed operating modes of aerodynamic pipe.
