Experimental and computational analysis of a tangent ogive slender body at incompressible speeds

Abstract

A combined computational and experimental analysis was performed on a tangent ogive body with very low aspect ratio wings in the '+' (plus) orientation at Mach numbers 0.1, 0.2 and 0.3, with the aim of developing a database of global force and moment loads. Three different span to body diameter ratios were tested with aspect ratios of 0.022, 0.044 and 0.067. Aerodynamic loads were obtained and flow visualization was performed to gain an understanding of the lee side flow features. It was found that the global loads were
