The turbine-engine inlet flow distortion methodology addressed in this document applies only to theeffects of inlet total-pressure distortion. Practices employed to quantify these effects continue todevelop and, therefore, periodic updates are anticipated. The effects of other forms of distortion onflow stability and performance, and of any distortion on aeroelastic stability are not addressed.The guidelines can be used as necessary to create a development method to minimize the risk of inlet/engine compatibility problems. The degree to which guidelines for descriptor use, assessmenttechniques, and testing outlined in this document are applied to a specific program should beconsistent with the expected severity of the compatibility problem.
