Abstract

In the article the problem of predicting of liquid rocket engine specific impulse is discussed. Brief discription of the structure oj specific impulse losses is given. Losses due to irregularity of combustion products distribution are given special attention. New method of calculating such losses on the basis of experimental data and results obtained with the aid of this method are shown.

Keywords:

liquid rocket engine, specific impulse.
