Equation of Motion of an Interstellar Bussard Ramjet with Radiation and Mass Losses
Semay, Claude; Silvestre-Brac, Bernard
European Journal of Physics, v29 n6 p1153-1163 Nov 2008
An interstellar Bussard ramjet is a spaceship using the protons of the interstellar medium in a fusion engine to produce thrust. In recent papers, it was shown that the relativistic equation of motion of an ideal ramjet and that of a ramjet with radiation loss are analytical. When a mass loss appears, the limit speed of the ramjet is more strongly reduced. However, the parametric equations in terms of the ramjet's speed for the position of the ramjet in the inertial frame of the interstellar medium, the time in this frame and the proper time indicated by the clocks on board the spaceship can still be obtained in an analytical form. The non-relativistic motion and the motion near the limit speed are studied. (Contains 4 figures and 1 table.)
