Abstract

Volvo Aero has developed the turbines for Hydrogen and Oxygen turbopumps for the Vulcain and Vulcain 2 engines used for Ariane 5. For the new European upper stage engine, Vinci, Volvo Aero has the same role as during the Vulcain development being responsible for the turbines.
In Europe there are presently a number of technology programs to prepare new technology for new ELV engines, for example Vinci demo and Vulcain X program
This paper will present how Volvo Aero is preparing the turbine technology for the next cryogenic ELV engines. The requirements on Engine, Turbopump and turbines will be described. Potential new concepts which meet the new requirements will be discussed for GG and Expander cycle engines.
Also the need for new method development to increase the accuracy of turbine behaviour as well as decreasing development risks will be presented.
Furthermore a demonstration program for a new generation turbine for the Hydrogen Turbopump, TPX, will be presented and also the Vinci demo program.
