10. Large-scale facilities (2) • Engine test rigs, • Wind tunnels, • Solar furnace, • Solar fields, • Autoclaves, • Traffic tower.

11. Projects with Russia using ISTC networkboundary conditions • DLR is a public organisation, which has to develop and to finance the German fundamental research and technology development for their fields of responsibility. • Any cooperation has to be realized strictly without exchange of funds (In difference to the European Industry we are not allowed to pay for research work). • Initiator of joint projects shall be the Russian/Ukrainian side, this is a limitation for our activity. • The “DLR International Cooperation department” disposes of mobility funds for initiation of cooperation projects. Bearing a part of the Russian/Ukrainian travel costs – we could show our collaboration interest at ISTC/STCU.

13. Friction Stir Weldinga technology for connecting metal structures, used by DLRagainst the main stream (composite materials) • Temperatures well below the melting point • Excellent tensile and fatigue strength • No splatter, no fume • Low energy consumption • Low shrinkage • No filler wire • Simple preparation of the weld seam • Good mechanical reproducibility • No welder certification required

18. Conclusions • ISTC/STCU is a very convenient management instrument for cooperation with Russian and Ukrainian research Organisations (more for Ukrainian?). • There is a really need for cooperation – especially in Aeronautics – to meet the European industrial requirements of the future (Association of European Research Establishments in Aeronautics (EREA) in the European Research Area). • STCU could be very useful in the transformation process of the Ukrainian space industry and the process of military launcher utilization.
