Inlet Total-Pressure-Distortion Considerations for Gas-Turbine Engines
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.
The intent of this document is to provide a basic understanding of the effects of inlet total-pressure distortion on the performance of gas turbine engines, particularly in military applications. The document was revised to incorporate an Introduction containing material inadvertently omitted from revision B.
