In the last weeks, we completed the manufacturing of the oxidizer tank for the Compass rocket. For the manufacturing, we used a newly developed technology, which will help us to reduce the structural mass of the larger N2ORTH rocket significantly. The oxidizer tank is mainly made of winded CFRP and coated with a thin layer of fluoropolymer on the inside to ensure N2O compatibility. The connectors for the upper and lower part of the rocket are mounted on the bulkheads and reinforced with additional CFRP winding. The first pressure tests showed excellent results and we are confident about the upcoming launch of Compass.
