High Speed Acoustic Measurements in Cavities

Abstract

This document constitutes the final technical report under the terms of US Air Force Office of Strategic Research Grant No F49620-98-l-0167. This grant provided funding to undertake an experimental research programme to investigate the acoustic environment of single and tandem box cavities at high supersonic speeds to establish the effects of Reynolds number, Mach number and model scale. The initial statement of work and planned milestones are reproduced. The status of effort and achievement are reviewed against initial targets. All objectives and milestones have been achieved. A review of the research carried out is given, sample results provided and conclusions and recommendations from the work are summarized. These summaries provide only a brief precis of the research programme, results and conclusions as detailed accounts are provided in two referenced and published technical reports.
