The use of a Phase Change Material Heat accumulator is becoming a first choice for thermal engineers. After a successful flight on-board Ariane 6 maiden flight, implementations in a future low-cost private European launcher and an hypersonic glider, the use of this passive heat absorber has become the final choice of trade-off with other thermal systems. In particular, the performance, reached...
Advanced Data Handling Architecture (ADHA) standard [1] (under development by ESA with industrial partners) is a standard for the on-board computers and data handling systems to assure interoperability and cost efficiency. It utilizes standardized plug-in electronic modules interconnected in larger enclosures called electronic boxes. A similar philosophy was adopted to an older standard called...
Passive thermal control of a satellite is typically performed using multilayer insulation (MLI) blankets. The current state-of-the-art method for MLI fixation makes use of stand-offs, which are glued to the spacecraft structure, and clip-washers, which fix the blankets on these stand-offs. This method is highly reliable and has a wide heritage, however it is time-consuming for several reasons:...
The solar absorptance () and emissivity () are important engineering parameters to evaluate the performance of thermal control sub-systems or power generation at solar panels. In the context of future lunar missions, it is important to investigate the effect Lunar Dust Simulants (LDS) contamination on thermo-optical properties and thus performance of thermal and power functional...
Adjustable Support Structure for Optical Sensors, ASSOSS - Thermal System
ASSOSS is a novel structure designed to provide structural support and efficient thermal management for optical space sensors, developed in a joint venture between Space Structures GmbH, BTU Cottbus-Senftenberg, and Fraunhofer IAP. This innovative project focuses on integrating ultra-lightweight materials,...
High heat-rejecting technology becomes increasingly necessary as communication capacity grows for the next generation of geostationary communication satellites. Engineering Test Satellite 9 (ETS-9) is being developed by JAXA to demonstrate bus technology for new high-throughput communication satellites and is scheduled to be launched in fiscal 2025.
The main technologies to be newly...
The thermal design of equipment and space platforms is a difficult task due to the large variability of the thermal conditions during the orbit and the strict constraints imposed by other subsystems. In the past years, several strategies have been studied to meet these constraints while reducing the signature of the thermal control subsystem. These techniques encompass different algorithms...
Spacecraft antennas are always directly exposed to the space environment. Suitable choice of materials and processes is the basis of successful performance.
Active Antennas with very high dissipative units have to be thermally controlled in order to guarantee that the temperatures of all items will remain below the upper limits with appropriate margins. One option is to use suitable...
Optical Solar Reflectors (OSRs) constitute the physical interface between radiator panels and outer space and allow for radiative cooling of the spacecraft. The performance of an OSR is defined mainly by two Thermo-Optical (T.O.) parameters: solar absorptance α (the lower the better) and IR emittance (the higher the better). The market of OSRs is dominated by OSR quartz tiles, and by...
