Book Description
The work presented in this report forms a continuation of the fundamental studies on the generation and radiation of supersonic jet noise, reported in technical reports AFAPL-TR-72-53 (six volumes), AFAPL-TR-74-24, and AFAPL-TR-76-65 (four volumes). The total noise from a supersonic jet is taken to consist of contributions from three independent noise sources: (1) small-scale turbulent mixing noise, (2) noise from large-scale turbulence structure, and (3) shock-associated noise. The generation, radiation and prediction of each of these noise components is described in this report. In addition, the mean and turbulent flow characteristics of heated and unheated, subsonic and supersonic jets, measured by a laser velocimeter system, are also presented. Finally, a computer program for the prediction of jet noise, based on fundamental principles as far as possible at the present time, is presented and described in the form of a user's guide. A complete listing of this computer program is given in the Appendix volume (Volume 11) of this report.

Book Description
A series of experiments was conducted for the purpose of clearly isolating and quantifying the noise sources associated with supersonic jet noise and for establishing the effect of refraction on the radiated field of these sources, as well as establishing the range of validity of available theoretical formulas for predicting the radiation field characteristics of these sources. Turbulent mixing region noise from a fully expanded supersonic flow exhausting from a well designed convergent-divergent nozzle was measured over a very wide range of operational parameters. This Appendix contains computer printouts obtained from a jet noise data analysis program for turbulent mixing region noise. (Author).
