Aerodynamic caracteristics and vortex asymmetry control around a circular cone

The structure of the vortex asymetry around a circular cone at high incidence and Reynolds numbers of order 104, is related to the existence of at least four vortices shed from the apex and exhibiting vortex breakdown points correlated with the sign of the lateral force. Control of the lateral force by injection points out three regimes, and not two as usually admitted, corresponding to inversions of the lateral force direction.
