Atmospheric Remote-sensing Infrared Exoplanet Large-survey (Ariel) is the fourth medium-sized mission (M4) selected in the context of ESA's Cosmic Vision 2015-2025 programme and is scheduled for launch in 2029. Thermal control of the payload is based on a passive and active cooling approach. Passive cooling is achieved by a V-Groove shield system that takes advantage of the favourable thermal...

The models used to analyse the thermal performance of spacecraft are complex, and characterise states and behaviours of a spacecraft for all subsystems and at various levels of abstraction. Configuring thermal models is historically a technical and time-intensive process, requiring intimate knowledge of the specific model and sub-models, as well as the spacecraft, its mission and the physics...

In the frame of Arianespace mission analysis, thermal coupled loads analysis are needed to predict the thermal behavior of spacecraft on ground and during the flight. With the latest and upcoming launchers of VEGA-C and ARIANE 6 it was the occasion to update the technical specification for payload thermal models.
To introduce this new specification, a quick presentation of launcher (Ariane...

It is common for CubeSat missions to use simplified analysis models, leveraging software suites which are tuned for thermal analysis with coarse mechanical and power dissipation models of spacecraft components. The inherent non-linearity of thermal simulations and the complexity of typical boundary conditions for realistic satellite components often result in this trade-off and reduction in...

OBJECTIVE: The role of the Thermal mathematical model is to help in the design of the spacecraft Thermal Control System. Temperature uncertainty must be decreased as much as possible and kept under control, to achieve this whole process must be well thought-out especially validating thermal model via TVAC test. The purpose of this study was to determine steps and measures that allow us to...

Thermal analysis for space systems encounters a significant bottleneck in computing radiative heating contributions to the heat transfer problem, particularly when transparent and specular materials come into play. In this study, we introduce an innovative implementation that harnesses the remarkable parallel processing capabilities of ray tracing on Graphical Display Units (GPUs)....

This work presents a new implementation of the radiative exchange factors calculations for 3D geometry using Graphics Processing Units (GPUs) with hardware-accelerated ray tracing capabilities.
Radiative exchange factors (REFs) represent the overall exchange of thermal radiation energy between two surfaces. Although there are analytical solutions for particular geometric configurations, in...
