This paper discusses the development of wind tunnel test capabilities at the University of Illinois at Urbana-Champaign to obtain the aerodynamic performance of highly-coned subscale wind turbine rotor configurations as part of the ARPA- E funded project to design extreme-scale Segmented Ultralight Morphing Rotors (SUMR). The scaled rotors were designed to be configurable for various coning and pitch angles. Many challenges were associated with testing at these small scales numbers due to the small forces generated, Reynolds number effects, and the high rotor rotation rates required. Rotors were tested at freestream velocities from 4.5 m/s to 9.5 m/s at various coning angles (0 to 50 deg) and pitch angles (4-8 deg). The results obtained can be used to further validate blade element momentum theory (BEMT) codes developed for design and analysis of highly-coned rotors.
