Abstract:
The present work investigates the effect of introducing a boat tail radius for hammerhead launchers in order to reduce separation and to study its effect on the unsteadiness. For this end, experiments have been carried out in a transonic wind tunnel on the Coe and Nute Model 11 hammerhead configuration for which various boat tail radii have been applied. Preliminary analysis shows that the separation is indeed decreased however a more detailed analysis and PIV experiments will be conducted to further quantify the flow field unsteadiness.
