The theoretical results of the present work reveal a significant interaction oncoming vortex ring propellant muzzle gases with backward blood spatter. It is shown that there even possibility droplet from backspatter will fully turn around by powerful and land behind victim. Such predicted outcome confirmed experimental data reversed drop trajectories observed in experiments conducted second par...

The interest in interplanetary space travel has stimulated much discussion on the desirability of using nuclear, rather than chemical, energy for the spacecraft propulsion. Comparisons of the relative merits of various propulsion systems have been extensively discussed in the literature. The results of such studies yield a diversity of conclusions, depending on the assumptions which are made in...
