An Investigation of the Performance of a J52-P-8A Engine Operating under the Influence of High Bleed Flow Extraction Rates.

Abstract

The uninstalled performance characteristics of a J52-P-8A engine operating under the influence of bleed flow extraction rates in excess of the standard specification limits were experimentally evaluated. This investigation was undertaken as part of the Circulation Control Wing Flight Demonstrator Program to assess engine capability of supplying airflow to power the high-lift aerodynamic system incorporated on the Flight Demonstrator and define a data base from which higher confidence level analytical short takeoff and landing performance evaluations could be obtained. Results of the investigation indicate that bleed flow extraction rates significantly greater than the standard specification limits are obtainable. An endurance evaluation of the engine operating under the influence of the high bleed flow extraction rates indicates that these extraction rates do not adversely affect the J52-P-8A engine. The results of the endurance evaluation should serve to qualify the J52-P-8A engine for the proposed Flight Test Program. (Author)
