Comparing the integral thrust-economic characteristics of ramjets in a wide range of speeds and flight levels

Ramjet engines are proposed to be used as accelerating rocket engines in aerospace systems and high-speed transport aircrafts. In this paper, five different schemes of such engines to be installed on high-speed wide-range aircrafts are described. The results of calculations and the comparison of their thrust-economic characteristics are presented. The specific thrust and specific impulse are compared and analyzed.
