[Via Satellite 12-17-2014] The European Space Agency<\/b> (ESA) has made a test \u2014 originally created for its Rosetta comet-chaser mission \u2014 readily available to all European space missions. The test helps ensure propellant tanks will not crack up when subject to aggressive chemical corrosion.<\/p>\n
\u201cStress corrosion cracking has been termed the \u2018sleeping monster\u2019 of the aerospace industry, first highlighted in the 1950s with cases of aircraft landing gear unexpectedly cracking overnight,\u201d said Giancarlo Bussu at ESA\u2019s Materials Technology section.<\/p>\n
The multicell frame design, built under ESA contact by Germany\u2019s space agency DLR<\/b>, allows many samples to be tested at once, providing a large amount of data for statistical analysis. It is used for hazardous chemical tests at DLR\u2019s facility in Lampoldshausen and non-toxic testing at ESA\u2019s European Space Research and Technology Center (ESTEC), in Noordwijk, the Netherlands.<\/p>\n
\u201cSince then it has been employed during the development of ESA\u2019s Vega launcher, as well as for validating a greener alternative to propulsion simulants for ground-based vibration testing of satellites,\u201d said Tommaso Ghidini, head of ESA\u2019s Materials Technology section. \u201cRight now, it is being prepared for testing more environmentally friendly space propellants, as well as assessing the effectiveness of chromium free protective coatings.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
