We have highly qualified scientific and technical staff, as well as extensive scientific and research experience in conducting expertise in aerodynamics and flight mechanics for both civil and military aircraft and helicopters.

The scope of our activities includes conducting research and development work carried out for the needs of the economy and industry, in particular for:

• aviation,
• automotive,
• construction,
• energy,
• space technologies,
• shipbuilding industry,
• defense industry,
• railroad industry, and
• sports.

We conduct unique scientific and R&D work in applied aerodynamics on a national and international scale. Four wind tunnels, including the largest wind tunnel in Central and Eastern Europe, allow us to realize extremely accurate wind tunnel research.

Our research infrastructure is one of the most advanced in the field of applied aerodynamics in the world. The experiments we conduct here facilitate the design and optimization of new and existing aircraft structures.

The upgrades carried out in the laboratory respond to international market demand in fluid mechanics and the high requirements of economic and industrial sectors.

Wind tunnel tests – scope of services

• aerodynamic testing for the Polish and foreign aerospace industry;
• tunnel testing of non-aeronautical aerodynamics for the automotive, construction, energy, space technology, sports, shipbuilding, defense industries, incl:
  • environmental wind resistance testing,
  • aerodynamic studies of wind power plants that are modern technologies in power generation,
  • aerodynamic testing of models of power units and cooling towers,
  • aerodynamic testing of ground and air transportation means;
• scientific and research activities in applied aerodynamics within the framework of the European Framework Programs;
• implementation of market research services for domestic and foreign customers;
• close cooperation with aviation industry giants, technical universities and units in the R&D sector.

At the laboratory where tunnel testing is carried out, the following systems and benchmarks have been implemented:

1. QMS under ISO 9001:2015 standard,
2. Laboratory Management System in accordance with the requirements of PN-EN ISO/IEC 17025:2018-2 supported by Accreditation Certificate No. AB 129 granted by the Polish Center for Accreditation, and
3.  Internal Control System standards.

Technical test results obtained at the laboratory are recognized by both the International Standard Organization (ISO) and the International Laboratory Accreditation Cooperation (ILAC).

Wind tunnel testing – equipment:

State-of-the-art measuring equipment allows us to carry out unique tunnel tests at the highest level.

Pressure measurements	DTC Initium	Up to 512 pressure measurement points at up to 650 Hz
Weight measurements	Aerodynamic balance set	Measurement of forces up to 14,000 N and moments up to 3,000 Nm
Visualization measurements	3D PIV – DANTEC DYNAMICS	Measurement using imaging anemometry In the velocity range 0-90 m/s and 0.2-2.5 M

For pressure measurements, we use two state-of-the-art multi-channel DTC Initium systems from Measurements Specialies ( the former Pressure Systems Incorporated) to measure pressure at up to 512 points (256 channels each) at up to 650 Hz for each channel.

The weight measurements are carried out using strain gauge aerodynamic scales, which vary in design, number of measuring axes, measuring range and mounting method.

The latest measurement system, located in our laboratory, is a multi-channel National Instruments system based on the PXIe architecture, based on an 18-slot PXIe-1085 chassis with a throughput of up to 12 GB/s, controlled by a PXIe-8135 controller with a NI 8260 disk array. Multichannel measurement cards with the PXIe architecture are installed in the chassis for measuring values of voltages, currents, temperatures, accelerations and forces.

Visualization of the outflow of test objects is carried out by measuring the two-dimensional velocity field of flowing air in low- and high-velocity tunnels using the technique of particle image velocimetry (PIV).

We have 2D2C PIV (2D – two dimensions, 2C – two in-plane velocity components), 2D3C (2D – two dimensions, 3C – three in-plane velocity components, Stereo-PIV) and 3D3C (3D – three dimensions, 3C three in-plane velocity components – volumetric measurements). For three-dimensional particle image velocimetry (PIV 3D) measurements, we use a Dantec Dynamics AS system, purchased in 2013, based on a specialized Dantec Dynamics DualPower 425-10 PIV laser with 425 mJ power for 532 nm per cavity and 10 Hz frequency with a 2000 mm optical arm, with a Dantec Dynamics HiSense 610 camera set equipped with excellent Canon lenses and the latest Dynamic Studio 4.10 software.
