92. Qualification and Applications of Phase Change Material (PCM) Heat Capacitors for Space MissionsMr Nicolas Nutal (CRM Group), Romain PEYROU-LAUGA (ESA)10/10/2023, 14:00thermal control technologies
PCM are materials selected for their high latent heat, which the phase transition (melting and solidifying) at the relevant temperature range is able to absorb and release a large amount of energy. They are usually stored in hermetically sealed container which is thermally coupled to the dissipative unit. Although already existing for a long time and used on several Space missions, PCM...

Heat capacitors are often used in space application to control temperatures during high transient heat loads or alternating hot/cold periods. Due to their purpose, they are characterized by high thermal inertia. In addition, in order to lower their mass (with respect for example to a similar solution made out completely of metal), they can use materials, such as Phase Change Materials (PCMs),...

Development of aerobraking MLI and deployable flaps
Go to contribution page
EnVision, the upcoming medium class mission to Venus, will implement an aerobraking maneuver in the upper Venus atmosphere, in order to decrease velocity and reach its final mission orbit. In addition to the body of the satellite, it is intended to use dedicated aerobraking flaps, as extensions of the solar array assembly. During breaking,... -

Development of generic MLI flap for spacecraft interface ring
Go to contribution page
The launch vehicle adapter (LVA) is used to connect spacecraft to the launch vehicle. The spacecraft interface ring, which connects the S/C to the LVA, remains exposed after separation, when the spacecraft is released to its target orbit. The unprotected and exposed interface ring on the spacecraft represents thus a significant... -

High-performance computers designed for space applications face significant challenges related to excessive heat generation and high-power density within confined volumes. These issues arise due to the intense computational demands required for Earth observation space missions, future space data centers and systems in spacecrafts for processing data of all kinds. Managing heat dissipation and...

Mr Philippe Paul Bert (Heatself), jean-paul Dudon (THALES)11/10/2023, 17:00thermal control technologies
The thermal control of satellites requires technologies that can effectively heat sensitive areas, while alleviating the constraints associated with this need.

Nowadays each piece of equipment or subsystem may require one or even several heating lines, which imposes constraints such as:
- Need to multiply the lines in order to guarantee a certain temperature homogeneity
- Each line... -
Jan Philipp Möller (Max Planck Institute for extraterrestrial Physics)11/10/2023, 17:30thermal control technologies
The camera head of the Wide Field Imager (WFI), which is to fly on the x-ray telescope ATHENA, is a compact system requiring the integration of three separate temperature regions. One will be the environment temperature of the instruments support structure. The other two temperature environments are governed by the requirements of the detector front end electronics and the detector itself. To...
