Abstract
The upper stage of the European rocket Ariane V will be equiped with the cryogenic expander cycle engine VINCI. Liquid hydrogen (LH2) and liquid oxygen (LOX) are transported from the fuel tanks to the combustion chamber by means of turbopumps, which themselves are driven by an expansion of warm and highly compressed gasous hydrogen in the turbines. The necessary heat input into the hydrogen takes places in the regenerative cooled combustion chamber wall structure.
