Introduction
Purpose
problem statement
aoa varies strongly, especially at low tsr
low cp compared to hawts
lack of elucidation on aerodynamics of pitched turbine
Expected
Outcomes
reduced aoa fluctuation
increased CP
stable torque production
elevated efficiency
hypothesis
implement blade pitching to account for changing aoa
Significance of research
objective
Optimize the blade to control the aoa
increase Cp using active pitching
understanding aerodynamic of pitched turbine
Motivation
Narrow down
lower CP than hawts
ever changing aoa
