Abstract

For the numeric computation of aerospace transportation systems an efficient, three dimensional, unstructured code for high performance computers was developed. By Moore's law the computational power doubles every 18 to 24 months. Therefore the code was designed for optimisation of the full configuration of a transport system with running engines, when the available computation power allows this. In detail the physical modeling of the flux transport is described, regarding acceleration technics, grid generation, grid adaptation, grid deformation and visualization. The simulation of a new type of linear nozzle is presented and the coupling of the simulation of fluid and structure is applied to the aeroelastic problem of transsonic flutter.
