Aerodynamics of Asymmetric Sabot Discard
Abstract
Experimental results are presented which examine the pressure distributions upon projectiles during the portion of the launch cycle which involves strong aerodynamic interference between the flight body and sabot components. Particular attention is given to the simulation of asymmetric sabot discard geometries since these configurations result in transverse loadings upon the projectile. The pressure distribution in a given section of the projectile surface is shown to be strongly influenced only by the flow field associated with the sabot component facing that section. The basic features of the flow are similar in both the symmetric and asymmetric cases. The experiment is compared with existing analytical models and recommendations for improvements are made.
