Increase of Pulse at Interaction of Gas Masses in the Pulsejet Engine Exhaust Unit

Abstract

On the basis of the experimental studies of a pulsejet engine and performance analysis of other engines of the same type, the increase of the pulse at interaction of the spent gas masses within the exhaust unit is shown. This effect has been substantiated by the experiments in vacuum. Correlations have been obtained to determine propulsion characteristics of a pulsejet engine in flight conditions; the said correlations take into account gas mass addition. Fields of this effect application are defined.
