Experimental Investigation to Inform the Design and Development of a High-Speed Projectile
Abstract
An experimental study involving force and moment measurements, high-speed shadowgraphy, and surface oil flow visualization was conducted on a generic axisymmetric projectile configuration with low aspect-ratio fins at the Florida State University Polysonic Wind Tunnel. The main objectives of this study were to validate numerical simulations and generate an aerodynamic database for a range of Mach numbers (0.4 to 4) and control surface deflections. Results showed an excellent match between the experimental and numerical data for the baseline configuration. Surface oil flow visualization and shadowgraph images showed a few complex and interesting flow features such as body vortex and fin interactions, shock-shock, and shock-boundary layer interactions. Control surfaces were very effective for pitch and roll control at all Mach numbers and control deflections tested. The database generated will be very useful for further validation of the numerical tool and the design of control laws.
