Abstract:

This paper reviews some current aspects of time-variant, spatial total-pressure distortion and other forms such as swirl, static-pressure distortion, planar-wave perturbations of total pressure, and total temperature distortion. Engine response considerations include the influence of engine spool coupling on stability, developments in the modelling of total-pressure circumferential extent effects, and swirltotal-pressure interactions. Guidelines for the formulation of distortion descriptors and performancestability assessments are reviewed.
