Vakumdaki malzemelerin gaz çıkışı genellikle ihmal edilir. Tipik olarak, bir rulmandaki yağ kaybı gibi denklemin sadece bir tarafı dikkate alınır. Ancak, yağın optik bir alet üzerinde yeniden süblimleşmesinin potansiyel olarak ölümcül sonuçları göz ardı edilebilir. - Uzayda üzerinde bulanık bir yağ tabakası olan bir lensi silecek kimse yoktur. Genel bir kural olarak, sıcak yüzeylerin gaz çıkarma olasılığı daha yüksektir [...]

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 [...]

Coefficient of Moisture Expansion:
A challenging measurement task

tarafından|2024-01-26T13:06:59+01:0027. Eylül 2023|Uzay|

A high degree of dimensional stability is often required for aircraft and spacecraft components. In order to evaluate polymeric composite materials for aerospace applications the coefficients of thermal expansion (CTE) and moisture expansion (CME) have to be determined. Coefficient of Moisture Expansion (CME) is defined as the ratio of change in strain and mass variation due to the moisture desorption or absorption.  For the determination of the CME the change of length and the mass [...]
