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...
Humanity is tackling the challenge of creating a permanent human presence on the Moon, and Canada is contributing by funding novel ideas for Moon infrastructure. With support from the Canadian Space Agency under the Lunar Surface Exploration Initiative, Canadian companies are actively developing solutions to explore and stay for extended periods on our planet’s satellite.
Under this...
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...
Traditional spacecraft thermal modelling processes can be costly and time-consuming due to manual effort required by engineers to build and update thermal models. Recent advancements in AI and machine learning have enabled automation of many thermal engineering tasks including geometry construction, model reduction, mesh creation, etc. In this technical presentation, we will showcase the...
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...
EcosimPro is a versatile mathematical tool that excels in modeling and simulating both continuous and discrete systems, making it particularly adept at non-causal simulation. It is capable of effectively handling Differential-Algebraic Equations (DAE) and Discrete Events, offering applicability across various problem domains. Originally funded by the European Space Agency (ESA) to simulate...

The presentation will begin with an overview of the two releases of Systema issued the past year, then a segment will be dedicated to the operational validation of the last Long Term Support (LTS) version.
Systema 4.9.2P1 was released last April 2023 to address some...
Radian is a thermal analysis software conceived to provide agility to engineers, both at modelling and computing processes. Our software is accessible through a regular web browser and counts on a scalable network of computing resources in the cloud. Thermal analyses are supported by the Databank, a catalogue of satellite components and other reusable entities. The underlying simulation engine...
ESATAN-TMS provides an advanced thermal modelling environment for the thermal analysis of spacecraft and launch vehicles. The suite is continually being enhanced to meet current and future requirements of space projects, and to support the specific needs of thermal engineers. This presentation will focus on the latest development to be included in the coming ESATAN-TMS 2024.
