Comparison of Kinetic, Equilibrium, and Frozen Rocket Expansion Obtained atDifferent Propulsive Parameters for Launcher and Spacecraft Engines

摘要

Kinetic expansion data expressed by the kinetic specific impulses are presentedand compared with equilibrium and frozen specific impulses. These specific impulses and other propulsion related data were calculated beforehand and stored in large data files to assist in system analysis of spacecraft and launchers. Kinetic data concerning spacecraft propulsion indicate kinetic losses up to 20, while the kinetic losses for higher thrust levels such as the space shuttle main engine lie in a regime of only 0.1 and therefore could be neglected. The data files are available on request by the author.
