Upper Stage Test Stand P5.2
The highly complex and extremely powerful P5.2 upper stage test facility completes the portfolio of the DLR test site with its ability to qualify entire upper stages.
The PHOEBUS upper stage demonstrator consists of a tank for liquid hydrogen mounted on a tank for liquid oxygen. For the first time, the tanks are made of carbon fibers and operated with cryogenic fuels, in particular hydrogen. This will be the world's largest demonstrator of a carbon fiber cryogenic tank to date. The PHOEBUS project is part of the "Future Launchers Preparatory Programme" of the European Space Agency ESA.
Together with MT Aerospace, ArianeGroup will develop, build and test the PHOEBUS upper stage demonstrator made of carbon fiber composites.
In future, the PHOEBUS upper stage demonstrator will be tested on the P5.2 upper stage test bench at DLR in Lampoldshausen. The tests include the filling and refueling cycle, the pressure build-up and the emptying of the tanks.
