Axial compressors are critical components in aero-engines and industrial gas turbines, where blade vibration and aerodynamics are inextricably linked to performance and safety.

Compressor rotor blade vibrations are commonly categorized as either synchronous or non-synchronous occurrences. Forced response in rotor blades occurs due to circumferential flow disturbances, such ...

On our three test rigs, the multi-stage twin-shaft axial compressor test bed, the transonic cascade wind tunnel, the inter compressor duct and the radial compressor test bed, we measure various gas ...

Foundational work on transonic compressor performance has also validated that tandem rotor blades can achieve significant improvements in flow turning and efficiency compared to conventional ...

The transonic cascade wind tunnel (TGK) is installed at the Institute of Propulsion Technology in Cologne.This large-scale facility is used for investigations on compressor blade cascades; it is the ...
