Investigation of acceleration effects on missile aerodynamics using computational fluid dynamics

Abstract

In this paper the authors describe the implementation and validation of arbitrarily moving reference frames in the block-structured CFD-code EURANUS. The paper also present results from calculations on two applications involving accelerating missiles with generic configurations. It is shown that acceleration affects wave drag significantly. Also, it is shown that strake-generated vortices move significantly in turns. These results clearly show the necessity of including the acceleration effects in the calculations
