Abstract
A critical review of recent experimental data tends to confirm the validity of previously published asymmetric flow concepts: 1) That the maximum side force to normal force ratio (the maximum normalized side force) on slender bodies of revolution at high angles of attack and zero sideslip occurs in the critical Reynolds number range where the maximum local flow separation asymmetry can occur; 2) that body motion can lock in a driving vortex asymmetry to produce self-induced body coning; and 3) that laminar vortex separation may occur on the cylinder of an ogive-cylinder at high angles of attack, even when the nose experiences turbulent separation. In addition, the present analysis offers a realistic explanation as to why a minimum normalized side force is realized at a Reynolds number slightly above that for the maximum normalized side force. c d
