A method has been developed for quantitatively accounting for flow non-uniformity in an inlet. This method is recommended for use as an additional indicator of design excellence during the early inlet development cycle, prior to the time firm engine indices can be established. A concept of flow quality, Q, has been defined for this purpose. It is related to the area weighted total pressure below average at the exit of the inlet system. This quality indicator can be related to all existing engine indices and was screened from 24 candidate definitions. The total pressure below average can be a function of time, in which case quality will include unsteady effects.
