Permeation von Gas durch Vakuummaterialien – Massenspektrometrische Apparatur zur Bestimmung der Gasdurchlässigkeit
Ziel der hier vorgestellten Arbeiten ist die Untersuchung der Gasdurchlässigkeit von Materialien, die in unbemannten Flugobjekten eingesetzt werden sollen. Auf der Grundlage eines Helium‐Lecksuchgerätes wurde dazu eine Messapparatur zur Bestimmung der Permeabilitätskoeffizienten aufgebaut...
The aim of this research is to study the gas permeability of materials being used to create elements of unmanned aerial vehicles. The measurement system for gas permeation coefficients of composite materials is designed on the basis of a helium leak detector. Due to permeation through the Viton sealing the smallest flow that can be correctly measured by the system is 10‐10 Pa · m3/s. Verification...
