Analytical and Experimental Investigation of Ejector-Powered Engine Simulators for Wind Tunnel Models

Abstract

Ejector-powered engine simulators (EPES) that produce representative engine inlet and exhaust effects in wind tunnel models are currently under investigation at the Arnold Engineering Development Center (AEDC). Studies summarized in this report include theoretical and experimental investigations of single-stage, cold-flow EPES and theoretical investigations of two-stage, cold- flow EPES and of single-stage EPES driven with heated jets. Existing AEDC jet pump and ejector-diffuser analytical models were used to predict EPES exhaust- to-inlet total pressure ratio, inlet airflow, and velocity distributions during the jet mixing process.
