Abstract
To design launch pads and test facilities properly it is necessary to predict the noise emission of rocket engines as well as specific exhaust jet created tones. As existing prediction models are limited to Jet engines with low jet Mach numbers, tests were performed to study the application in rocket engines ith significant higher jet Mach numbers. Two subscale rocket nozzles were tested, differing in the contour type and the related exhaust jet shock pattern. The tests reveal several prominent tones of different types that appear only during fully-attached flow state.
