Abstract:

Power-on base drag values estimated for an existing rocket-assisted projectile RAP show that a major portion of the rocket impulse is expended in overcoming drag rather than in extending the range of the projectile. A parametric study of the effects of thrust level, afterbody geometry, and nozzle position on power-on base drag shows that the losses due to drag can be significantly decreased.
