Abstract
The measurement of convective, pressure wave-packets in the near field for a full-scale engine is desired because these wave packets can be used to predict the far-field sound. In this proposal we outline a plan to develop software, design a robust mechanical structure, design a microphone array system that can withstand the outside elements, and perform laboratory scaled experiments. The software and hardware proposed for data acquisition has already been developed by us for other applications. Phase I will be used to modify the existing software and hardware for simultaneous measurement of near-field and far-field pressure. A preliminary design of a robust mechanical structure for full-scale engine design will be prepared during Phase I which will allow Phase II to focus on the manufacturing and assembly of the structure. A microphone array will be incorporated into the structure during Phase I (optional) after a better understanding of microphone positioning is gained by performing scaled experiments during Phase I and Phase I (optional). At the end of the Phase I effort, we believe we will have provided all the necessary tools to transition into a Phase II effort where full-scale engine tests are to be performed.
