Engine Erosion Prevention - A Comparison Of Four Separators

The Naval Air Propulsion Test Center (NAPTC) has conducted a series of thorough evaluations of several models of static, inertial-type inlet particle separators as part of an overall program to help advance the state-of-the-art of engine foreign object damage prevention. During these evaluations, separators were tested to determine particle separation efficiency, foreign object damage protection, resistance to clogging and inlet pressure loss and distortion. A brief description of the test units and the highlights of the results of this program are presented.
