Navier-Stokes Computations of Finned Kinetic Energy Projectile Base Flow.

Abstract

A computational fluid dynamics (CFD) study of finned kinetic energy projectile base flow is presented for a 105-mm M735 projectile in supersonic flight. A parabolized Navier-Stokes technique is used to compute the attached flow of the forebody and fins. An unsteady Navier-Stokes technique is used to compute the flow in the base region. Several CFD solutions for freestream Mach numbers 3, 4, and 5 are presented, and the modeling approach and computational requirements are discussed. The computed zero-yaw drag coefficients are compared to range-acquired values, and the computed base flow structure is briefly examined.
