Combustion Generated Noise in Turbopropulsion Systems.
Abstract
Continuation of experimental and theoretical work on the problem of combustion generated noise in turbopropulsion systems is presented. Tasks completed during the current period have been (a) experimental and theoretical correlation of noise power and spectra from open premixed flames of propane, propylene, ethylene and acetylene-air, (b) crosscorrelation of C2 emission with the far field acoustic pressure, and (c) experimental and theoretical investigation of ducting effects upon the noise radiating capability of the flame. The noise radiation from simple flame types is now understood with sufficient theoretical and experimental detail that estimates may be made for combustion noise in turbopropulsion systems.
