Compressor stability
Abstract
Various operating modes and conditions of the gas turbine which may cause compressor stall are considered. The behavior of a compressor in stall is explained because the engineer, although designing to avoid stall, must consider the possibility of stall and what control measures must be taken to recover engine operability. A major cause of stall is inlet distortion, that is a nonuniform pressure and/or temperature profile at entry to the compressor. The causes and effects of distortion are discussed. A set of graphics illustrating the above is also presented.
