Experimental Study of the Acoustic Processes of a Demonstrator of the Center Body Propulsion System Using Acoustic Visualizations

Experimental research and processing of the results of acoustic processes carried out during the interaction of high-temperature turbulent supersonic non-design jets of the demonstrator of the center body propulsion system with a flat impenetrable barrier by the method of acoustic visualizations. For the first time, the patterns of the acoustic field during the interaction of the jet with the obstacle for different frequency ranges are obtained.
