Abstract
A comprehensive wind tunnel investigation on a cone-clyinder body with and without fins was conducted over a Mach number range of 2 to 4. The tests were conducted as a function of angle of attack varying from -5 degree to +15 dreees at different roll orientations. The experimental programme consisted of flow visualization, aerodynamic force and moments, static pressure and flow velocity measurements taken in the DREV indraft wind tunnel. The wind tunnel had an up stream sting support system to conduct interference-free base pressure measurements. The surface adn base pressure results are compared with similar tests that were conducted at the French-German Research Institute of Saint Louis (ISL), and the reduced aerodynamic coefficients are compared with estimated values from Projectile Design and Analysis System (PRODAS). Some differences were noticed between the results from the two wind tunnels and most of these were accounted for from the different boundary layer thicknesses.
