The prototype tanks for liquid hydrogen (LH2) and liquid oxygen (LOX) will be manufactured in near-real size, meaning they will be about 2.5 meters high, with a diameter of 3.5 meters. Over the next three years, an upper stage demonstrator will be developed and manufactured, which will have to prove its functionality in the final system test conducted by ArianeGroup GmbH. satellites) into space: Each rocket equipped with a black (so called because of the dark material CFRP) ICARUS upper stage will be able to carry an additional payload of up to two tons. This saves mass, which has a positive effect on the cost of each rocket launch, and makes it possible to transport more so-called payload mass (e.g. In the technology development PHOEBUS (Prototype Highly OptimizEd Black Upper Stage) for the future optimized upper stage*) called "ICARUS", full use is being made of CFRP: The use of the smart material carbon fiber should make it possible to largely dispense with metallic components of the upper stage tanks and structures. The advantages of the smart material CFRP (carbon fiber reinforced plastic) are in demand for the commissioned development of the propellant tanks and structures PHOEBUS, a large-scale demonstrator for the future black rocket upper stage MT Aerospace AG, a subsidiary of the space and technology group OHB SE, was awarded a contract by ArianeGroup GmbH as part of the Future Launcher’s Preparatory Program of the European Space Agency (ESA) for the advanced technology development for a future black upper stage for the European launcher Ariane 6.
