RISThe Unstable Behavior of Low and High-Speed Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By far the greater part of our understanding about stall and surge in axial compressors comes from work on low-speed laboratory machines. As a general rule, these machines do not model the ...
High-Speed Compressor Surge With Application to Active Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses the mechanics of surge as observed on the high-speed axial compressors of modern aero-engines. It argues that the initial stage of the instability consists of a high-amplitude ...
Stall Inception and Development in an Axial Flow Aeroengine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the phenomenon of stall and surge in an axial flow aeroengine using fast response static pressure measurements from the compressor of a Rolls-Royce VIPER engine. It details ...
On the Use of Atmospheric Boundary Conditions for Axial-Flow Compressor Stall Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a novel way of prescribing computational fluid dynamics (CFD) boundary conditions for axial-flow compressors. The approach is based on extending the standard single passage ...
Experiments in Active Control of Stall on an Aeroengine Gas Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes work carried out between 1989 and 1994 to investigate the application of “Active Stall Control” to a Rolls-Royce Viper turbojet. The results demonstrate that stall control ...
Combustion Instability Investigations on the BR710 Jet Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the development of the BR710 jet engine, audible combustor instabilities (termed “rumble”) occurred. Amplitudes measured with test cell microphones were up to 130 dB at around 100 Hz. ...
