Evaluation of an Ejector-Powered Engine Simulator at Transonic Mach Numbers

Abstract

An experimental program was conducted to evaluate an air-driven ejector for use as a turbo-engine simulator in wind tunnel testing. The use of an engine simulator will provide the capability to simultaneously simulate inlet and afterbody flow fields of a turbo-powered vehicle. The ejector-powered engine simulator (EPES) was fitted to the right-wing nacelle of a 0.06-scale B-1 aircraft model. The B-1 model was chosen for the investigation because of the availability for comparisons of inlet and nozzle afterbody data previously obtained in the Arnold Engineering Development Center (AEDC) Propulsion Wind Tunnel Facility Propulsion Wind Tunnel (16T) using conventional test techniques. A limited amount of flight data from the B-1 flight to wind tunnel correlation program was also available to aid in determining the effectiveness of the EPES as a wind tunnel test tool.
