The T-3 low-speed wind tunnel with closed circulation, continuous-flow, open-ended measuring zone with a diameter of 5 meters and 6.5 meters length. Dimensions, motor power (5.6 MW) and air speed (100 m/s) allow to rank the T-3 tunnel among the world’s leading low-speed wind tunnels.
In addition, the T-3 wind tunnel is equipped with an innovative secondary flow system with
diameters of SF400, SF150, SF80, SF50 allowing to obtain additional air flow with a maximum
mass flow rate of 45 kg/s, 6kg/s, 2 kg/s, 1kg/s respectively and Underpressure Installation.
The SF80 and SF50 installations also allow the working medium temperature to be increased to 270°C. Unique installations allow internal flow testing of aircraft engine components or their models under simulated take-off and landing conditions with elevated outlet gas temperatures
