A Study of Asymmetric Vortex Shedding behind Missiles at High Angle of Attack using Dynamic Solution Adaptive Meshes.

Abstract

Vortices about the leeward side of cones at incidence become asymmetric past a critical incidence ratio. They consequently produce large side forces that lead to in flight control and maneuverability problems. The origins of this asymmetry have yet to be fully understood. Questions exist as to the nature of the asymmetry instability, the bifurcation process that occurs as the solution transitions from symmetric to asymmetric, and the numerical requirements for its computation. The reported research was initiated to seek answers to these questions.
