Abstract In this paper, a simple technique for calculating the ideal ejector thrust augmenter of a jet engine is presented. It is based on the well-known method for averaging the parameters of a nonuniform gas flow with the entropy of the initial flow being unchanged. Making use of the technique presented, we compare the calculated data on the pressure ratio in the gas being ejected as well as the thrust boost coefficient with those obtained by the other authors. Also shown is the existence of the thrust boost maximum in the ideal and real thrust augmenters when the value of the ejection coefficient is approximately equal to 100.
