Keywords: Transonic Flow, High Reynolds Numbers, Experimental/Computational Aeroelasticity

Preparation and conduction of aeroelastic windtunnel experiments are presented with a supercritcal elastic wing in the transonic flow regime in the cryogenic windtunnel in ETW at Reynolds numbers up to 70 million. Topics reach from model design, construction and qualifying to blind numerical predictions and first results of windtunnel experiments.
