Recently FOTEC started the development of 3D-printed heat pipes as a prospective thermal management solution for a high-power CubeSat thruster. The use of 3D printing could improve design flexibility and adaptability in geometrically confined situations, while enabling the heat pipe to be manufactured in one process, minimizing the number of thermal interfaces.
This contribution presents the...
With the miniaturization of space-borne sensors, more powerful payloads are anticipated to be used in small satellites. Therefore, new thermal concepts are required to cope with the increasing thermal dissipation and the negative effects. This paper presents a new thermal control concept to thermally standardize small satellites with power dissipation problems and making them thermally...
In the scope of Ariane 6 development, thermal analyses are performed on the cryogenic cavities of the launcher 1st and 2nd stages. The Vulcan Aft Bay (VuAB), or cavity near the Vulcan 2.1 engine, experiences extreme heat differences between the engine exhaust, booster plumes, aerothermal fluxes, and its bottom liquid hydrogen tank and associated lines. Furthermore the thermal environment on...
Compact efficient Counter Flow Heat EXchangers (CFHEX) or recuperators are crucial components of recuperative coolers, such as Joule-Thomson and Turbo-Brayton coolers. Also in cryogenic systems that apply a convective cooling loop, in which a working fluid is circulated by a warm pump and cooled by a cryocooler, high-effectiveness recuperators are essential. In a collaboration project of ESA,...
Thermal analyses are performed throughout the entire life cycle of a space project, from the first rough architecture trade-offs to the last in-orbit simulations.
In general, they consist in building a more or less complex thermal model, running different sizing cases and post-treating them. These activities are conducted by “thermal analysts” who are specialized in the different pre-post and...

During this presentation, we will compare and evaluate the different workflows available in Simcenter 3D PCB Exchange and Simcenter 3D Space System Thermal for printed circuit board assembly analysis in the context of spacecraft thermal design. Component reliability is heavily dependent on temperature and so PCA thermal design and simulation is an important aspect of spacecraft development....
There are current necessities of real-time simulation and satellites model exchanges with launchers. We are developping a geometrical model reduction (currently manualy done in the industry) complementary with a TMM reduction module (done by tools such as TMRT). A budget of faces for GMM is almost always imposed (Launcher or DSS constraints). The presented model reduction tool is physics...

To prevent thermal induced breakdown, thermal modelling is a crucial task during each design phase of a new space mission. Monte Carlo ray tracing, while computationally demanding, is usually the go-to method to simulate thermal energy transfer. State of the art thermal modelling suites, such as ESATAN-TMS, usually rely on a CPU-based implementation of Monte Carlo ray tracing.
