Book Description
This volume contains a summary of all the work accomplished in a detailed investigation of the noise characteristics of supersonic jet aircraft, as well as a summary of items in an exploratory program. There are three main sections. The first summarizes the problems with existing theories at the time the contract was initiated. The second outlines the criteria for a unified self-consistent theory of aerodynamic noise generation, and presents, a brief derivation of Lilley's equation which is the basis for the theoretical studies in jet noise generation and radiation. The third section summarizes the work accomplished.

Book Description
The report presents a series of specific theoretical studies directed toward the solution of jet noise generation and radiation, upstream noise radiation and combustion noise generation. Three theories are presented. Lilley's work is a new theory of jet noise generation, based on identification of acoustic and source generation terms. The acoustic 'converted wave equation' derived includes the Pridmore-Brown/Mungur shear refraction term. Plumblee presents a theoretical analysis and numerical solution techniques for solving for the radiation field from a source within a jet flow and specifically deals with radiation from an acoustic distribution initally specified at the end of a circular exhaust duct termination through the jet flow to the surrounding medium. Finally, Strahle presents a theory on afterburner type combustion noise generation and radiation. Order of magnitude analyses are made in an attempt to estimate acoustic power levels and refraction effects are also investigated. (Author).
