Computational Fluid Dynamics (CFD)

CFD supports the aircraft and automotive development on a similar level as wind tunnel test campaigns. Numerical methods feature some significant advantages: they reduce the initial cost and effort for preliminary configuration investigations and enable the expansion of the flight regime to be analyzed well beyond the technical capabilities of a wind tunnel.

However, the close link between numerical and experimental methods create valuable synergies: development time can be reduced and calculated results can be validated to confirm the level of their accuracy. By having both engineering capabilities under one roof, RUAG Aviation increases the engineering efficiency and the reliability of the acquired engineering results.

Computational fluid dynamics calculations and code maintenance of the intensively used NSMB (Navier Stokes Multi Block) are made possible by RUAG’s subsidiary CFS Engineering.
