School of Engineering Department of Mechanical and Aerospace Engineering 190 Active Support to Experimental Studies for Research in Aero-Acoustics Supervisor: Stephane REDONNET / MAE Student: KIM Subin / AE Course: UROP 1100, Fall UROP 2100, Spring This study investigates adaptive blade twisting to enhance wind turbine efficiency under variable operating conditions. BEMT simulations on the NREL Phase VI wind turbine demonstrate that optimized twist angles consistently improve power coefficients across different wind speeds and tip-speed ratios. Results show predictable patterns in required adjustments, with greater modifications needed near blade roots and at higher wind speeds. These findings establish that morphable blade technologies can overcome the inherent limitations of static designs, offering a practical approach to maximize energy harvesting through dynamic adjustment to changing wind conditions. Active Support to Experimental Studies for Research in Aero-Acoustics Supervisor: Stephane REDONNET / MAE Student: SWAN Oengus / AE Course: UROP 1100, Fall UROP 2100, Spring This iteration of the project explores the use of Vortex Lattice Method as a preliminary aerodynamic analysis method to evaluate the performance benefits of unconventional wingtip designs, with a focus on spiroid configurations. Using the Vortex Lattice Method implementation in the OpenAeroStruct software, we aim to compare the spiroid wingtip’s aerodynamic efficiency against conventional rectangular and rounded-tip wings. The analysis focuses on the trade-off in induced drag, lift distribution, and span efficiency. For more complex geometries, we expand the workflow to require an integration of open-source meshing tools to make a compatible mesh with an accurate representation of the geometry that can be used within the OpenAeroStruct framework.
