Wake Region Perturbation for Base Drag Reduction

Abstract

Fumer technology promises beneficial results in terms of imparting terminal effects characteristics to selected ammunition. Fumers should not be employed, however, strictly to reduce time of flight. Fumer projectiles at a selected range have considerably higher striking energy, and should therefore be considered for use where marginal penetration performances is expected. An optimized fumer round would ideally have some degree of programmed burning of the pyrotechnic composition inherent in its design. A good fumer must produce low molecular weight gases at very high temperatures. Generally speaking, the use of fumers mades sense if the projectile in question is optimized with respect to its contour (low drag shape). A practical compromise would appear to be a ballistically sound projectile having an optimized contour (low drag shape) and a tracer element which serves both as a fire control aid (bright tracer) and as a fumer.
