Abstract
This living document describes the present status of the Ariel payload thermal interfaces definition. An Ariel payload thermal model has been developed in the ESATAN-TMS environment to analyse and define the main couplings between the service module and the payload, as well as the interfaces within the sub-systems inside the payload in flight representative conditions. From the payload unit requirements and the thermal analysis results it is possible to evaluate predicted temperature and loads at internal/external interfaces. At the beginning of the document the general thermal architecture of the payload is presented. The main external (to the spacecraft) and internal (inside the cold payload) thermal interfaces are identified and the relative assumptions/definitions are described. Finally, the heat fluxes at the interfaces and the main specifications from the thermal point of view are reported. Keywords: thermal design and analysis, thermal model, spacecraft thermal control, cryogenics, exoplanets, infrared spectroscopy
