Özet:

The main objective of this study is to make a numerical model of direct connected ramjet test facility which is used for ground tests of supersonic air breathing propulsion systems. Conceptual design of a direct connected ramjet test facility is performed. 1 dimensional transient numerical model is made according to this conceptual design. Numerical model is made by using 1 dimensional computational fluid dynamic code FLOWNEX. Validation of the numerical model is performed by comparison of test data. After the validation, numerical model is used to analyze the test facility dynamics and the design parameters. A procedure is developed to generate a test condition of a ramjet engine. This procedure is used to create a flight condition and a ramjet engine is tested on the numerical model.
