Aerodynamic Analysis of Optimized Bending Body Configurations with Trajectory Simulations

Abstract

A bending-body design of the Air Force Finner projectile was investigated as a maneuver technology using Euler and Navier Stokes simulations, as well as an optimization algorithm. A strictly bent-nose configuration was selected for focused investigation, the results of which informed the setup and execution of the optimization studies. The optimization studies identified similar optimal configurations all strictly bent-body configurations for each Mach number investigated (2.0, 2.5, and 3.0). The strictly bent-nose configuration was simulated in coupled NavierStokes trajectory simulations, which found up to 60 g of maneuver authority. Strictly bent-nose and strictly bent-body configurations as well as hybrid options were found to have similar performance with niche advantages in different ways that could be selected as control technology for extreme maneuvers.
