Critical analysis of the idea of the kinetic jet engine. Space Colonization Journal, Issue 4, 2014.
This paper analyzes the idea of kinetic jet engine in the context of interstellar flight. It is shown that this concept is hopeless, and the errors have a fundamental nature. But the idea of acceleration by means of kinetic energy is actively promoted in the Internet, and is supported by some members of the academic community. Critical analysis of this idea would eliminate it from consideration as untenable.
