The processes addressed in this Aerospace Information Report (AIR) apply to the acquisition and validation of dynamic total-pressure and distortion data from CFD models simulating turbulent flows in inlets. The results of these processes can be used in the formation of an inlet-flow-distortion methodology that addresses turbine-engine operability assessments.
Progress is being made in Computational Fluid Dynamic (CFD) methods for correlating with experimental results for internal aerodynamics such as inlet steady-state total-pressure recovery and distortion. Development efforts are focusing on time-accurate CFD technology to estimate inlet peak-dynamic distortion. Validated solutions from CFD tools must be demonstrated to warrant use in official turbine-engine stability audits and/or for selecting worst-case distortion patterns for engine-qualification test demonstrations. This document presents procedures for processing time-dependent total-pressure records from test and CFD, along with approaches for validating time-dependent CFD results used to estimate inlet dynamic-flow distortion.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
