Main CNT Labs


Aerodynamic Department


 

Applied aerodynamic laboratory

Aerodynamic laboratory/The Lab  performs aerodynamic research for land and water based transport (automotive, water, railroad) and the building industry. In our aerodynamic tunnels, various types of wind resistance tests on stationary objects are carried out. We have access to five wind tunnels, including a trisonic wind tunnel and the largest in Poland (5 m test chamber) low-speed wind tunnel, all equipped with advanced instrumentation and calibration equipment.

  • T-3 Wind Tunnel

The T-3 Wind Tunnel is a closed-circuit, continuous-flow low speed tunnel with a 5 meter diameter open test section which was modernized in 2015.

Typical tests include measurements of forces and moments, surface pressure distribution,  models flow visualisation of various aircraft, helicopters, buildings, ships, cars, trains and two-dimensional airfoils.

Tests involving dynamic stability, deformation of aeroelastically scaled model, earth surface and off-body flow measurements are also performed.

The T-3 wind tunnel is one of the few research facilities in the world which have an ability to investigate  tests of internal flows with a simultaneous main flow around test models applied by using the Secondary Flow Installation.

The unique system allows to perform complex wind tunnel tests of various types of aircraft structure parts, engine parts, under simulated take-off or landing, taking into account also elevated temperature of the gas inlet.

Aircraft models with up to a 4m wing span, or half models of 4 m semi-span or bluff body (buildings) of 3 m high or 2,5 m2 cross section (perpendicular to flow direction) or rotor model up to 3 m diameter can be tested.

In the non-aeronautical tests a special flat plate is fixed to the test section. The flat plate boundary layer is manipulated to simulate the Earth’s surface wind’s mean velocity distribution and turbulence profile.

The T-3 Low Velocity Tunnel is a part of Aerodynamic Laboratory, certified by Polish Centre of Certification (Polskie Centrum Akredytacji, PCA Certificate no. 129).

Calibration and certification of aerodynamic scales, measurements of forces, moments, pressure distribution and flow visualization is in accordance with international standards.

Contractor has implemented an ISO 9001 quality system.
