In the last few weeks, we were able to improve the performance of our HyFIVE engine. The following video shows a test with a freestanding nozzle expansion part, as it is required for the CFRP casing. The nozzle is made of winded silica fibre. More testing of such components will take place in the coming weeks. With only a few minor adjustments to the design to be tested, the first test of the CFRP casing comes closer and closer. We are looking forward to see HyFIVE flying with our Demonstrator Rocket Compass in only a few months!
