Description

The aerodynamics and flight dynamics of projectiles are being investigated using computational and experimental techniques at subsonic, transonic, and supersonic flight velocities both independently and in a cooperative fashion. The computational methods typically utilize Navier-Stokes or hybrid Navier-Stokes and large eddy simulations to investigate fluid dynamic phenomenon associated with the flight dynamics of unguided and guided flight vehicles. Important research issues include grid generation/resolution, turbulence modeling, flow separation, and unsteady flow phenomenon. Access to a wide variety of high-performance computing platforms exist both on-site and at other DOD sites to include a variety of scalable parallel architectures. The experimental methods most commonly employed for projectiles are the on-site spark range facilities. These facilities allow for the complete aerodynamics and flight dynamics of guided and unguided projectiles to be determined over the first 100 m to 200 m of their trajectory depending on their size. Important research issues relating to the flight dynamics opportunities could also exist to leverage on-site telemetry systems for longer range understanding or off-site wind tunnels for a more in-depth understanding of the flight vehicle’s flow physics.
