On 15 and 18 May 2017 we have started the testing sequience of the carbon composite nozzles, which where manufactured by the Laboratory of Polymers at the Federal University of the Rio Grande do Sul (URFGS). Were performed full time tests, which proved the lifetime of the nozzles with different types of the heat insulation technologies.

The numerical studies made earlier by the Laboratory staff were validated by the current tests.
