Evaluation of an Airjet Distortion Generator used to Produce Steady- State, Total-Pressure Distortion at the Inlet of Turbine Engines

Abstract

A performance evaluation of an airjet distortion generator system used to produce steady-state, total-pressure distortion at the inlet to a turbine engine was conducted. The capability of the system to duplicate screen- generated, parametric distortion patterns (180 deg, one per revolution; tip radial; hub radial) and to maintain a constant composite distortion pattern over a range of airflows is presented. A comparison of the effect of inlet distortion produced by screens to that produced by the airjet distortion generator system on the stability characteristics of a present-day turbofan engine is described.
