Carmen, liquid propulsion systems simulation platform

Abstract

CNES Launchers Directorate (DLA) has to maintain a high level of expertise to achieve its missions regarding the exploitation of the Ariane 5 family launchers and to prepare the future of launchers. For this purpose, developing and using numerical simulation tools is of key importance. CARMEN software is CNES reference tool for simulating propulsion systems from their design to their exploitation. CARMEN regroups several CNES software packages. Among them are: CARDIM, for engine thermodynamics and geometric design, and CARSTAT/CARINS, for analyzing functional behavior of propulsion systems in stationary (CAR-STAT) or transient (CARINS) modes. This paper extensively presents CARMEN software development status and capabilities.
