Abstract:

This report describes the major research activities carried out and the principal results obtained during a three year research effort by The University of Tennessee Space Institute for the Federal Aviation Administration. The major objective of this research was to develop techniques for reducing the noise generated by high velocity jet streams exhausting from a wide variety of nozzle configuration. In addition to exploring techniques for noise suppression andor redirection, emphasis was placed on investigating the physical mechanisms at work in generation, suppression, and redirection of aerodynamic noise. The report consists of three volumes and is divided into several sections each dealing with a separate part of the research effort. This volume contains an overall summary of the work, a description of the facilities used and a description of the results obtained on linear arrays of circular nozzles and dual nozzles with shrouds.
