BALLISTICS RANGE FIRINGS FOR DETERMINATION OF DRAG AND STABILITY OF MODELS OF FIVE POLARIS CONFIGURATIONS

Abstract

Drag and stability characteristics of models of five POLARIS re-entry body configurations were determined. The variable parameter for these configurations was the bluntness ratio of the nose. The investigation was conducted at Mach numbers between two and six. The boundary layer flow over the surface of the models was turbulent. It was found that the slope of the normal force coefficient is smaller the blunter the nose of the model. A maximum in static stability of the models was observed between Mach numbers two and three. The dynamic stability coefficients were found to be stabilizing.
