Low Speed Wind Tunnel (5 m)

Upgraded in 2015, this low-velocity wind tunnel is a closed-loop tunnel, with an open measuring space, which has 5 meters in diameter and is 6.5 meters long. Dimensions, engine power (5.6 MW) and wind speed (90 m/s) place this tunnel among world’s leading low-velocity wind tunnels.

Additionally the wind tunnel is equipped with an innovative IPW400 and IPW80 secondary flow systems generating additional air flows, with the maximum mass flow rates of 45 kg/s and 2 kg/s, accordingly. The IPW80 system allows also the medium temperature to be raised to 250oC. This unique system permits testing of aircraft engines’ internal components or their models under simulated takeoff and landing conditions and in increased exhaust gases temperatures.

As part of the Aerodynamics Research Laboratory research activities, the following tests are performed in the wind tunnels:

These tests are performed on models of aircraft and helicopter parts (fuselages, rudders and stabilizers, main and tail rotors), buildings, navy ships, cars, trains and two-dimensional profiles.

Tests involving measurements of dynamic stability, aeroelastic model deformation and laminar flow parameters are also performed.

The wind tunnel allows testing of aircraft models with wingspans up to 4 m, non-aircraft models, which generate aerodynamic drag (residential and public buildings, bridges, industrial structures) with heights of up to 3 m and cross-section area (perpendicular to the flow direction) of up to 2.5 sq. m and models of rotors up to 3 m in diameter.

For tests not related to aviation, a special flat plate is installed in the measuring area. Correct velocity and turbulent airflow profiles are achieved by relevant modifications of this plate surface.

Trisonic Wind Tunnel

The Trisonic Wind Tunnel is in operation since 1965. The tunnel is a blow-down type with partial recirculation of the flow and can be operated in all three regimes, subsonic, transonic and supersonic. Mach number can be changed in range M = 0.2 – 2.3.

The tunnel is supplied from two spherical compressed air tanks with the combined volume of 2880 m3 and maximum pressure of 6.5 atm. The air is compressed using two 2000 kW centrifugal compressors and is appropriately purified and dried.

The average operating time of the wind tunnel, is:

Measurements are performed in a measuring chamber with the diagonal cross section of 0.6 x 0.6 m, which makes this wind tunnel one of the largest and fastest facilities of this type in Poland.


Low Speed Wind Tunnel (1.5 m)

The Low Speed Wind Tunnel is a closed-circuit, continuous-flow low speed tunnel with the 1.5 meter diameter open test section. The wind tunnel is powered by a 55 kW electric engine with 4-blade, constant-speed fan. The maximum velocity of the medium is 40 m/s. Capabilities:

Low Turbulence Wind Tunnel TMT

The Low Turbulence Wind Tunne is an atmospheric, open-circuit tunnel with two linked, closed, rectangular test sections. The front test section (1.75×2.28 m) is dedi-cated for the investigations for the airflow speed up to 8 m/s. The rear test section has smaller dimensions (0.5×0.65 m) but the airflow speed of 85 m/s may be achieved. The wind tunnel is powered by two direct-current engines, rated 5.1 kW and 64 kW, which are selected depending on the required agent velocity (40 m/s). Capabilities: In the TMT wind tunnel may be conducted:

Supersonic Wind Tunnel

The Supersonic Wind Tunnel is a blow-down type with a closed test chamber of 0.15 x 0.15 m. The velocity range is M = 1.22 – 3.5. The tunnel is used for research on aerodynamic phenomena related to supersonic flow like: boundary layer interaction with a shock wave.
