THERMAL MODELING OFSATELLITES : HEAT PIPES AND PAYLOAD OF A SPACEBUSNEO SATELLITE
Abstract: Thales Alenia Space is currently developing an innovative satellite platform with a two-phase fluid loop on board. The company uses two softwares in order to create models that are meaningful regarding physics: Amesim and e-Therm. The first one is used to describe fluid behavior in a circuit, while the second one is used to simulate conductive and radiative heat transfers in a satellite model but cannot be used to model fluid components. The interconnection of both software through a cosimulation module would allow to create dynamic models that would take into account both physical aspects. My internship was initially supposed to deal with the debugging of that cosimulation module, however a delay for its delivery forced me to reorient myself. First, I used e-Therm to model 3D heat pipes profiles, before working on the thermal model of a Spacebus Neo satellite in order to check the validity of the design choices that were kept for that satellite.
