Ball bearings dynamically testing in TVAC
Testing of ball bearings requires to pre-load them axially and/or radially. This needs manual operation by a technician. If bearings shall be characterized for different pre-loads, every change in [...]
Contamination monitoring of materials in vacuum
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 [...]
Cryogenic Materials Testing in Aerospace Engineering
In the dynamic world of aerospace engineering, innovation knows no bounds. As we push the boundaries of what's possible in aviation and space, one frontier that demands our attention [...]
Unveiling the Importance of Demisability Testing: Precision and Simplicity with Our Radiant Heater Service
In the realm of re-entry testing, ensuring the safe disintegration of returning spacecraft parts is paramount. At AAC, we underscore the critical significance of demisability tests. These tests simulate [...]
Enhancing Satellite Resilience: The Practical Significance of Thermal Vacuum Bakeouts for MLI in Satellite Missions
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 [...]
Outgassing of materials in vacuum
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 [...]
The mysteries of slip rings
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, [...]
Mikrostrukturanalyse bei AAC: Expertise in Werkstoff- & Bauteilanalyse
Die Charakterisierung von Materialien und Bauteilen auf makro- und mikroskopischer Ebene ermöglicht eine Vielzahl von verschiedenen Untersuchungen: • Identifizierung von Fehlermechanismen im Zuge von Schadensanalysen. • Qualifikation von neuen [...]
Cold welding under space and launch conditions
A common failure mode seen during the testing and operation of spacecraft is termed ‘cold-welding’ (‘coldwelding’, ‘contact welding’, ‘adhesion’, ‘sticking’ or ‘stiction’). Coldwelding is a solid-state welding process in [...]
CronHard – Achieving Stress Corrosion Cracking Resistance in Bearing Steel
Ball bearings are essential components in various mechanical systems, designed for their high hardness to ensure wear resistance and the ability to withstand high contact stresses. For many years, [...]
