Contamination monitoring of materials in vacuum

tarafından|2024-07-23T14:27:39+02:0023. Temmuz 2024|Space|

Contamination control is a critical aspect of risk mitigation for contamination sensitive surfaces in satellites. Molecular organic contaminants (MOCs) that are deposited on surfaces like lenses may decrease the performances of instruments. Common monitoring methods that are used in space business include: TQCM monitoring (Thermally stabilised Quartz Crystal Microbalance), RGA (Residual Gas Analysis), witness foils to collect contaminants for ex-situ analysis, infrared reflection-absorption spectroscopy (IRRAS) or X-ray Photo Spectroscopy (XPS).   The issue is … [...]

Enhancing Satellite Resilience: The Practical Significance of Thermal Vacuum Bakeouts for MLI in Satellite Missions

tarafından|2024-02-14T09:22:29+01:0014. Şubat 2024|Space|

Operating in the challenging environment of space, satellites contend with extreme temperature fluctuations, radiation exposure, and the vacuum of the cosmos. Essential for fortifying these satellites against such harsh conditions and ensuring their longevity, Multi-Layer Insulation (MLI) emerges as a key protective measure. This thermal insulation method, comprised of reflective foil layers separated by low-conductance spacer materials, plays a pivotal role in regulating temperature and maintaining the resilience of satellites in the unpredictable realm of [...]

Outgassing of materials in vacuum

tarafından|2024-01-30T08:06:36+01:0030. Ocak 2024|Space|

Outgassing of materials in vacuum is often treated neglectfully. Typically, only one side of the equation is considered, such as the loss of oil in a bearing. However, the potentially fatal consequences of oil resublimation onto an optical instrument may be ignored. - There is no one in space to wipe down a lens that has a hazy film of oil on it. As a rule of thumb, warm surfaces are more likely to outgas [...]

The mysteries of slip rings

tarafından|2023-11-20T14:52:05+01:0020. Kasım 2023|Consulting, Energy, Industry, Space|

A slip ring (in electrical engineering terms) is a method of making an electrical connection through a rotating assembly. Slip rings, also called rotary electrical interfaces, rotating electrical connectors, collectors, swivels, or electrical rotary joints, are commonly found in all rotary systems with electrical connections of sensors and receptors. They are a common building block in terrestrial and space applications, e.g. wind turbines, computer tomography scanners, solar arrays in space and many more. Tribological characterization [...]

Revolutionizing Materials Testing: Unleashing the Potential of High-Temperature, High-Pressure Experiments for Coatings, Sheets, and Beyond!

tarafından|2023-11-14T10:59:52+01:0014. Kasım 2023|Energy, Industry|

Novel materials and products, before their final application, must undergo a series of rigorous tests to demonstrate their ability to withstand physical, chemical, and/or environmental challenges. Autoclave testing provides a comprehensive evaluation by subjecting the materials to a combination of liquid, temperature, pressure, and, when necessary, different atmospheric conditions (such as air, Ar, N2) to simulate real-world scenarios in a controlled laboratory environment. These conditions are highly effective for simulating extreme conditions and rapidly assessing [...]
