Flow Manipulation of a Fin on a Flat Plate Interaction in High-Speed Flow by Means of Micro Flaps

Abstract

Previous work has been done by Massey and Bell of protuberances on fin-body interactions of high speed projectiles. Both computational and experimental analysis has shown that significant force multiplication can exist by modifying the boundary layer shock interaction of the fin and body. The devices used in these previous studies were relatively large (on the order of one third the fin height) and protruded beyond the boundary layer. The purpose of this study is to show the effects of multiple micro flap devices on the fin and flat-plate interaction problem. The aerodynamic mechanisms could then be incorporated into micro adaptive flow control schemes to control a projectile. Computational fluid dynamics will be used to analyze various configurations, including a validation against experimental data from Massey. Study of the various configurations will help to determine critical features and flow qualities necessary for favorable interactions.
