Abstract:

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. Shock-associated noise, both discrete and broadband, was investigated thoroughly. This Appendix contains sequences of data in the form of narrow band spectra illustrating the existence of these types of shock associated noise in the jet flows investigated. Author
