The Effect of Wrap-Around Fins on Aerodynamic Stability and Rolling Moment Variations

Abstract

This report presents the results of an investigation of the effect of wrap-around fins on missile rolling moment coefficient. This investigation was conducted for four fin configurations at free stream Mach numbers ranging from 0.3 to 2.86. The wrap-around fin was found to have a self induced roll moment at zero angle of attack that varies with Mach number. This effect was studied for several fin geometric configurations for the static moment case. Comparisons between the moments caused by the fin cant and wrap-around fins are shown for the rolling case.
