Product Code:SAE AIR5867
Title:A Current Assessment of the Inlet/Engine Temperature Distortion Problem
Issuing Committee:S-16 Turbine Engine Inlet Flow Distortion Committee
Scope: This report revises SAE ARD 50015 document to the AIR format. This report, as was the original, is intended to be a compliment to ARP1420B and AIR1419 documents issued by the SAE S-16 Committee on spatial total-pressure distortion. These previous documents addressed only total-pressure distortion and excluded temperature distortion.The subject of inlet temperature distortion is addressed in this report with some background and identification of the problem area. The status of past efforts is reviewed and an attempt is made to define where we are today. Deficiencies, voids, and limitations in knowledge and test techniques for temperature distortion are identified. Suggested approaches to fill these voids and a proposed temperature distortion methodology are presented. Successful techniques, employed to date, are reviewed and recommendations for future research work are indicated.
