Abstract
A systematic study of a number of flare-stabilized projectile geometries has been undertaken at the U.S. Army Ballistic Research Laboratory (BRL). Ten projectile configurations having identical forebodies and a variety of flares were tested in the BRL Aerodynamics Ballistic Range, and the results were compared to numerical computations based on two design codes and a parabolized Navier-Stokes (PNS) code. The design codes, in general, gave good results. The PNS code complimented these results by providing more details on the development of the aerodynamic forces. The results show the drag and stability tradeoffs involved for the different configurations. This information can be used to tailor the flare geometry to meet future mission requirements.
