On March 24th, 2021 HyEnD has tested its first rocket engine with a carbon fiber reinforced plastic (CFRP) casing. The casing consists of multiple layers of carbon fiber and is produced on our winding machine in our facilities at the MPA Stuttgart. This marks a big milestone in our STERN project participation, since the new, lightweight casing was one of the most ambitious goals of the project.
The resulting engine has a dry mass of only 0.95kg and can handle pressures of up to 100 bar / 1450 psi. Tests have shown stable and efficient combustion with a measured specific impulse of more than 210s.
