Graphical Solution for Performance of Continuous-Flow Jet Engines

A SERIES of charts for predicting the performance of the continuous-flow jet engine and its individual components is presented here.

Efficiencies of components as well as the momentum pressure loss in the combustion chamber (assuming constant cross-sectional area) are taken into consideration.

Performance of a typical jet engine under various operating conditions is calculated by means of the charts and graphed to show the effect of each operating condition on performance when all other conditions are held constant.

A set of large, usable charts similar to the figures in this paper may be obtained upon request to the Cleveland Laboratories, National Advisory Committee for Aeronautics.
