Fan Performance and Noise Test
We operate Europe’s largest anechoic chamber as a powerful tool for experimental validation during fan system development. Noise reflections from test facility walls are fully suppressed in the frequency range of interest, thus acoustically simulating free-field conditions, e.g. like on an airfield. At the same time, testing is not limited by adverse weather conditions or environmental limitations.

Universal Fan Facility for Acoustic (UFFA )
- To complement the noise test facility UFFA has been designed as a versatile and adaptable modular test vehicle to easily accommodate customer specific fan system hardware configurations in an existing test environment. Using a common hardware platform minimises the initial efforts required to design a test vehicle.
- We offer the complete package from concept, design and production of the test hardware up to testing. Modularity of the UFFA test vehicle allows for quick change of multiple test configurations in the test cell speeding up a specific test campaign significantly.
- The UFFA test vehicle is used for validation of hardware development (fan, OGV, liner, struts, nacelles, etc.), but also provides a realistic test case to improve calculation models (fan noise, propagation of noise in the bypass duct, noise insulation from liners, effect of noise on aerodynamics, effects of acoustic hardware on flutter).
UFFA test vehicle
- Nominal fan diameter of 869mm (34,2’) with a maximum rotational speed of 10,000 RPM.
- Bypass ratio is largely variable, depending on the layout of the fan module as specified by the customer
