Acoustic Loads on Hypersonic Engines

Abstract

The associated project aims to understand how acoustic loads are generated in supersonic combustion ramjets (scramjets) to control sonic fatigue in reusable hypersonic vehicles. <br/> <p>This knowledge promises to revolutionise flight by making space access more affordable than it is today. In this project, three aspects of flow phenomena commonly encountered in scramjet engines are being studied – shock/turbulence interaction, fuel injection in a cold supersonic cross-stream and shock/boundary layer interaction for both rigid and compliant surfaces. The intended outcomes include a better understanding of the processes above and construction of an experimental database to validate predictive simulation models that will enable the design of flight-weight reusable hypersonic vehicles. Benefits include reduced cost for access to space and the ability to design and develop advanced aerospace technology.</p> <br/> <p> This dataset contains <ul><li>(1) raw high-speed video and image files (.mcf) </li><li>(2) raw pressure transducer data files (.bin from PCB sensors)</li></ul> Complete information on the datasets can be found in the following publications: </p>
