Abstract : Turbine engine testing in ground test facilities cannot rely upon the simulation parameters that are common to aerodynamic testing in wind tunnels. The interfaces between the internal fluid dynamics of the engine and the external aerodynamics of the flight vehicle are sometimes simulated in wind tunnels and sometimes duplicated in engine test facilities. The choice is primarily dictated by test facility capability and finances available for test models. This paper discusses some of the testing techniques which have been used and denotes research efforts which are directed toward extension of test procedures and facility capability. In particular, applicable material from the recent AGARD Propulsion and Energetics Panel Symposium on Turbine Engine Testing is summarized and amplified. Some emphasis is placed upon airframe-inlet-engine testing and the development of testing capabilities for this purpose.
