This document addresses many of the significant issues associated with effects of inlet total-pressure distortion on turbine-engine performance and stability. It provides a review of the development of techniques used to assess engine stability margins in the presence of inlet total-pressure distortion. Specific performance and stability issues that are covered by this document include total-pressure recovery and turbulence effects and steady and dynamic inlet total-pressure distortion.
A small portion of AIR1419A was inadvertently omitted when the document was revised. The section that was omitted has significant useful information and will be reincorporated into the document in this revision.
