Rationale: The SAE S-16 Turbine Engine Inlet Flow Distortion Committee has developed an Aerospace Recommended Practice (ARP) and Aerospace Information Reports (AIR) describing measurement stations and techniques, and descriptors for different types of inlet total-pressure, planar-wave, and total-temperature distortion. There has been broad acceptance of these descriptors by the industry. Although a treatment for swirl distortion has been proposed, no methodology for swirl distortion has gained wide acceptance. When an accepted methodology exists for swirl distortion, this document will be updated to include it. This document provides a single source that contains the recommended measurement stations and techniques, and descriptors for total-pressure, planar-wave, and total-temperature inlet distortion.
