Characterization of Titan III-D Acoustic Pressure Spectra by Least-Squares Fit to Theoretical Model

Abstract

A theoretical model for the acoustic spectra of undeflected rocket plumes is fitted to computed spectra of a Titan III-D at varying times after ignition, by a least-squares method. Tests for the goodness of the fit are made.
