GKN Aerospace will develop and manufacture two full scale turbines for the Prometheus low-cost re-usable rocket engine demonstrator on liquid oxygen and methane propellants. The turbines will generate power for the methane fuel system, with the first turbine to be delivered at the end of 2019. Manufacturing will take place in cooperation with partners and at GKN Aerospace’s highly automated engine systems centre of excellence in Trollhättan, Sweden.
The new state of the art turbine with all its challenging loads – including very high pressure, high speed and high temperatures – incorporates the latest additive manufacturing (AM) technologies with higher performance, lower lead times and significant cost reduction. This innovative development will support the next step in AM: the use of this technology for future higher loaded critical components in terms of pressure, temperature and rotational speed.
GKN Aerospace’s space business unit, in Trollhättan, Sweden, has been active in the Ariane programme from its inception in 1974 until the current Ariane 6 partnership, and has made over 1,000 combustion chambers and nozzles as well as over 250 turbines for the Ariane rocket to date. Today it is the European centre of excellence for turbines and metallic nozzles, having contributed to the programme at every stage from initial research and development through cooperation with academia to the serial production.
Prometheus is an ESA funded program for a low-cost re-usable rocket engine demonstrator on methane propellant, with ArianeGroup as the Prime contractor.Email Post to a Friend
