The Generation and Radiation of Supersonic Jet Noise. Volume V. An Experimental Investigation of Jet Noise Variation with Velocity and Temperature

摘要

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 the radiation field characteristics of these sources. Results from the turbulent-mixing tests and the shock-associated tests are appended to this report in separate volumes. The turbulence noise 1/3 octave corrected data appear in Appendix I and the shock-associated narrow-band spectra appear in Appendix 2. (Author)
