On the Mechanism of Spike Stall Inception and Near Stall Nonsynchronous Vibration in an Axial Compressor

Daniel Moeller et al.

Summary: This paper investigates the aerodynamic and aeroelastic behavior of an engine-like transonic compressor stage through simulations, showing close agreement with experimental investigations. The research focuses on flow analysis during spike stall inception and nonsynchronous vibrations, as well as the aerodynamic structure of shear layer fluctuations in the rotor tip region. The study concludes with an analytical interpretation of shear layer fluctuations observed at the beginning of spike stall and near stall nonsynchronous vibrations.

Aerodynamic Investigation of a Composite Low-Speed Fan for UHBR Application

Martin Rodrigues et al.

Summary: An experimental investigation was conducted on a composite fan stage representative of a modern Ultra High Bypass Ratio (UHBR) architecture, revealing tip region overloading and extensive blade passage blockage. The performance of the fan and non-synchronous vibrations were analyzed through instrumentation and numerical studies, providing insights for future low-speed fan designs.

Interpretation of Stall Precursor Signatures

Christoph Brandstetter et al.

Summary: This article investigates unsteady aerodynamic phenomena near the stall boundary in axial fans and compressors, focusing on the rotating instability phenomenon that often occurs in the tip region under highly loaded conditions and is linked to blade vibrations. It discusses the challenges of interpreting measurements using spectra alone, emphasizing the potential for misinterpretation and the need for more advanced analysis methods beyond spectral peaks.

Analysis of a Linear Model for Non-Synchronous Vibrations Near Stall

Christoph Brandstetter et al.

Summary: This paper investigates non-synchronous vibrations by casting a reduced model in the frequency domain and analyzing stability for a range of parameters. It is shown how linear models can capture phenomena traditionally associated with aerodynamic nonlinearities under certain conditions. The study highlights the differences between convective non-synchronous vibrations and flutter, and identifies necessary modifications for quantitative predictions.
