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.


DLR – project:

Welding residual stresses in T-jointsand their impact on crack growth

V. S. Pisarev, I. Odintsev, K. Zimmermann, G. Biallas Central Aero-Hydrodynamics Institute (TsAGI), 140180 Zhukovsky, Moscow reg., RussiaInstitute of Material Research, German Aerospace Centre DLR, D-51170 Cologne, Germany

ISTC Project Title (for TsAGI): Stress determination on a base of advanced interferometric measurements of deformation response induced by local mechanical influence


• 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

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.
