Abstract:

This is a summary report of the results of a 13-month research program on the generation and reduction of supersonic jet noise. This program was planned as the first phase of a four-phase effort. Tasks compromising this Phase 1 program were as follows reviews and evaluation of existing theoretical models for supersonic jet noise generation and radiation development of the framework of a new, unified theory of aerodynamic noise development of a new theoretical model of turbulent mixing region noise development of a new theoretical model for calculating propagation and radiation of upstream noise a preliminary review of combustion noise tests on turbulent mixing region noise and shock-associated noise review of the problems of jet flow measurement and analysis development of new instrumentation for jet flow measurement establishment of full facilities for the total program formulation of the program for future studies.
