Combining Experimental Data, CFD, and 6-DOF Simulation to Develop a Guidance Actuator for a Supersonic Projectile

Abstract

A demonstration of steering a Mach 4 projectile using the guidance pins was successful * The combined CFD and Experimental efforts led to a greater understanding of the effects of the pins * EFD and CFD each used to get different but required forces and moments * Results could have been easily done without IFD * This in turn allowed us to better predict the results of the range tests * Less range tests were required because once the predictions were validated, it was proven we understood the aerodynamics * This saved substantial amounts of money * $10,000 bullets and 5 range operators and 2 PhDs add up fast * (As does destruction of the ADT alarm box)
