T-3 low-speed wind tunnel (5m)
Trisonic Wind Tunnel N-3
T-1 wind tunnel (1.5m)
The Low Turbulence Wind Tunnel TMT
We perform nationally and internationally unique scientific and R&D work in applied aerodynamics, including non-aviation aerodynamics.
We have four wind tunnels, including the largest wind tunnel in Central and Eastern Europe.
Our testing infrastructure is among the most advanced in the field of applied aerodynamics in the world. Ongoing experiments enable the design and optimization of new and existing aircraft structures. The modernizations conducted in the laboratory are a response to the needs of the international market in the field of fluid mechanics and the high requirements of the economy and industry sectors.
We have a qualified scientific and technical staff, as well as extensive scientific and testing experience in conducting expertise in aerodynamics and flight mechanics for both civil and military aircraft and helicopters. The scope of our activity includes conducting tests and development works perform for the needs of the economy and industry.

Aerodynamic tests – equipment
We have modern measuring equipment that allows us to conduct unique tests at the highest level.
Up to 512 pressure measuring points with a frequency of up to 650 Hz
A set of aerodynamic scales
Force measurement up to 14,000 N
3D PIV – DANTEC DYNAMICS
Measurement using image anemometry
For pressure measurements, we use two modern multi-channel DTC Initium systems by Measurements Specialies (formerly Pressure Systems Incorporated), used to measure pressure at a maximum of 512 points (256 channels each) with a frequency of up to 650 Hz for each channel.
We carry out weight measurements using:
- load cell aerodynamic scales,
- different in terms of construction,
- number of measurement axes,
- measuring range,
- mounting method.
The latest measurement system in our laboratory is the National Instruments multi-channel system:
- based on PXIe architecture,
- based on the 18-slot PXIe-1085 enclosure
- bandwidth up to 12 GB/s,
- controlled by the PXIe-8135 controller with the NI 8260 disk array.
Multi-channel measurement cards with PXIe architecture were installed in the enclosure, used to measure the values of voltages, currents, temperatures, accelerations and forces.
We visualize the flow around the tested objects by measuring the two-dimensional velocity field of the flowing air in low and high speed tunnels using the imaging anemometry technique – PIV.
We have PIV 2D2C (2D – two dimensions, 2C – two components of velocity in the plane), 2D3C (2D – two dimensions, 3C – three components of velocity in the plane, Stereo-PIV) and 3D3C (3D – three dimensions, 3C three components of velocity in volume – volumetric measurements). For three-dimensional imaging anemometry (PIV 3D) measurements, we use the Dantec Dynamics AS system, purchased in 2013, based on a specialized Dantec Dynamics DualPower 425-10 PIV laser with a power of 425 mJ for a wave of 532 nm per cavity and a frequency of 10 Hz with an optical arm with a length of 2000 mm, with a set of Dantec Dynamics HiSense 610 cameras equipped with excellent Canon lenses and the latest Dynamic Studio 4.10 software.
