In the past year, two versions of Systema have been issued.
First the V4.9.1 version of Systema-Thermica was released and is available to users in fall 2021. This new version provides some enhanced performances affecting the model creation process, such as for example selection in the meshing, and how node condensation is handled. Moreover some features of the STEP-TAS protocol have been...
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.
A major focus of ESATAN-TMS development this year has been on providing facilities within Workbench to further...
The thermal heat leaks in electrical harnesses become one of the major source of uncertainty in space thermal engineering especially for miniaturized systems as nanosatellites, microsatellites or where harness lengths are reduced. In parallel, the space systems become more and more power consuming including more and more electrical needs leading to a high dissipated power and high electrical...
In the early years of CubeSat technology the reliability of the missions was about 30-50%. However, over time the mission’s success rate increased up to about 74% in 2018 (based on Thyrso Villela et al., “Towards the Thousandth CubeSat: A Statistical Overview”). Nevertheless, there’s still a place for improvement due to high investment cost. Thermal control of a spacecraft is one of the...
During the design phases of a spacecraft development, a thermal model of the spacecraft is created that is used to predict the operational temperatures under a defined set of terrestrial and space environments.This thermal model involves a large number of inputs coming from a large number of sources. Some inputs, such as the thermal conductivity of a material are well defined and subject to...
In recent years, a focus of space exploration has shifted again to the surface of the Moon. There is a reborn interest of the study and utilization of the Moon. In this context, thermal engineers have to design space hardware for operation in the lunar environment. Detailed thermal analyses of hardware in the lunar environment requires complex thermal models and powerful software packages....
A recurrent industrial problematic lies in integrating sub-models into full and complex models, such as adding a spacecraft model into a launcher model. Thermal nodes clustering is currently proceeded manually by thermal knowledge from the technical expert, taking a substantial amount of time.
One of the milestones of the PhD funded by Dorea about Model Reduction for Space Thermal Simulation...
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 a new user interface enabling rapid development and implementation of customized...
Foam insulations are important thermal control elements for cryogenic upper stages. One of these, called "External Thermal Insulation" (ETI), was developed at ArianeGroup GmbH in Bremen for first use on Ariane 6. In particular, the thermal conductivity of the current ETI configuration has been characterized by tests. Further developments of the ETI are planned, where the thermal conductivity...
The ongoing project PROSPECT is aiming to land a drill (ProSEED) and a lab (ProSPA) on the surface of the Moon with the Russian Luna-27 mission planned for 2024/2025. The objective is to detect and quantify the presence of sub-surface ice in South Polar regions of the Moon. The environment is thermally challenging given the wide range of lunar surface temperatures and the varying lighting...
The harness sizing for space applications is driven by derating rules, which are specified in international standards and in particular the ECSS-Q-ST-30-11C Rev 1 (2011) , “Space Product Assurance, Derating EEE Components”, relevant for a wide range of European space projects. The respective standard, concerning wire and cable derating, is based on tests conducted in the 50’s and 70’s and...
