An Analytical and Experimental Analysis of Factors Affecting Exhaust System Performance in Sea Level Static Jet Engine Test Facilities.

Abstract

The study was motivated by a request from the Naval Air Rework Facility, NAS North Island, that work be conducted to obtain information on parameters affecting exhaust system performance in sea level static jet engine test facilities. The cost of pollution abatement devices makes it mandatory that accurate knowledge of flow parameters be developed. The study investigated by theory and experiment certain parameters of test cell design. A computer program based on the one-dimensional mass, momentum and energy conservation equations was developed. Components were designed to test on a scale of 24:1 the effects of varying exhaust system configurations. Theoretical results were found to be in good agreement with experimental data, indicating that the program may be used to analyze full scale systems. Recommendations for future development in the analysis and experimental program were made. (Author)
