SAE AIR5687A – Inlet/Engine Compatibility – From Model to Full Scale Development (Stabilized: Feb 2016)

This document reviews the state of the art for data scaling issues associated with air induction system development for turbine-engine-powered aircraft. In particular the document addresses issues with obtaining high quality aerodynamic data when testing inlets. These data are used in performance and inlet-engine compatibility analyses. Examples of such data are: inlet recovery inlet turbulence and steady-state and dynamic total-pressure inlet distortion indices. Achieving full-scale inlet/engine compatibility requires a deep understanding of three areas: 1) geometric scaling fidelity (referred to here as just ??????scaling??????) 2) impact of Reynolds number and 3) ground and flight-test techniques (including relevant environment simulation data acquisition and data reduction practices). The Model-to-Full Scale Subcommittee of the S-16 Turbine Engine Inlet Flow Distortion Committee has examined archives and has obtained recollections of experts regarding air induction system development experience to produce this document.
