Abstract
A scaling law for the prediction of flyover noise spectra of a single stream shock free circular jet from static experiments is derived. It is valid for unheated and heated jets. The theory is based on an experimentally supported similarity law for the influence of the flight velocity on the turbulent flow field of a jet. The resulting scaling laws for the difference between third octave spectra and the overall sound pressure level compare very well with flyover experiments with a jet engine and wind tunnel experiments with a heated model jet.
