Interactive CFD Ventilation Model for AIT Support

The on-orbit performance verification of the functions constituting a Space Manned System is one of the critical points of space projects.

During phase C/D of Node 2 & 3 and ATV Space station modules, the Alcatel Alenia Space - Italia approach for the verification of the design requirements related to the correct air distribution inside the Module habitable volume was to use a CFD virtual mock-up, derived by CAD models. These models were correlated with existing on ground ventilation tests and were extensively used during the project phase to evaluate the impact on the relevant ventilation requirements of possible internal module layout changes and item relocations.

This paper describes the developed tool capability and presents the results obtained in support to the Assembly, Integration and Test (AIT) phases.
