The Study by Visualization of Vortex Structures on a Warhead Wing, Apex Angle (ß)=68.6°

Abene Abderrahmane*

This study has been given prominence and confirmed by extensive documentation while recent visualizations observed in a wind tunnel have revealed that rectilinear vortex flows from different angles interacting with one another above warheads. My experimental research has indicated the many and very specific series, by visualizations of wisps of smoke trails, of vortex structures of a preferential nature above a warhead where β=68.6°. The positioning of those structures has thus been determined with regard to the application of very general criteria governing the stability of vortex flows. What have also been exposed are the specific aspects of vortex flows together with some comments concerning the bursting of vortices above the warhead. The purpose of this study is to optimize the connection between marine, air and land forms such as sails, the wings of aircraft, cars and trains – and the stability of fluid flows around such forms.
