Abstract
This living document describes the present status of the thermal analysis of the PLM of the ARIEL mission proposal, candidate for the ESA M4 launch opportunity. A general PLM TMM/GMM, both radiative and conductive, has been developed to simulate the main couplings between the SVM boundary and the PLM units in flight representative conditions, to evaluate predicted temperature and loads at internal/external interfaces. At the beginning of the document the general architecture of the payload is presented. In the following chapters the geometrical and thermal models are described together with the assumptions adopted for simulating the system behavior in terms of radiative and conductive couplings and loads. Finally the main results of the steady-state and transient analyses carried out so far are reported and commented. At this stage, this model represents the more detailed simulation tool for the ARIEL PLM thermal performances prediction. In future phases of the mission analysis, once the design will be in a more condensed state, dedicated detailed models of single sub-systems (Optical Bench, Instrument Radiator, Telescope Assembly) will be prepared for accurate simulations of the thermal behavior of these PLM units. This general model will be updated and correlated with the more detailed simulations to provide a reliable representation of the PLM thermal behavior and will be used for general steady-state and transient analyses. It will be maintained, in agreement with ESA and Industry, to become also be the TMM deliverable for representing the ARIEL PLM thermal design inside the general Spacecraft model. All ARIEL thermal modeling simulations are being developed in the ESATAN-TMS environment.
