Prediction and Comparison with Measurements of the Aerodynamic Characteristics of Flare-Stabilized XM910 Prototypes

Abstract

A systematic study of a number of flare-stabilize d projectile geometries has been undertaken at the US 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 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 trade-offs involved for the different configurations. This information can be used to tailor the flare geometry to meet future mission requirements. Keywords: Multi- stage projectile, Fast aerodynamic prediction, Aerodynamics of projectiles, Hypersonic aerodynamics.
