Abstract

The Zona technology/Duke University team process a challenging set of tasks to be accomplished in two years time that builds upon the very substantial progress already made in Phase I. Specifically, the 2D, Euler Euations CFD model (developed in Phase I)that uses a harmonic balance solution technique will be extended to include teh effects of viscosity (Navier-Stoke equations)and multiple structural modes. In parrallel teh 3D, Euler Equations CFD time linearized model (also developed in Phase I) whichalready includes multiple structural modes and uses a POD/ROM solution method will be extended to now include full dynamic nonlinear effects using harmonic balance solution; and then furtherextended to now include full dynamic nonlinear effecrs using aharmonic balance solution; and then further extended to include the effects of multi-bodies (e.g. wings plus tip missiles and stores).
