![]() This project enables innovation in wind turbine design by accelerating time to market through higher-accuracy early design iterations to reduce the levelized cost of energy. This AI-based design technology can capture complex non-linear aerodynamic effects while being 100 times faster than design approaches based on computational fluid dynamics. Copyright © 2009 John Wiley & Sons, Ltd.The INTEGRATE (Inverse Network Transformations for Efficient Generation of Robust Airfoil and Turbine Enhancements) project is developing a new inverse-design capability for the aerodynamic design of wind turbine rotors using invertible neural networks. Testing the ability of the ATEF to cancel out the load variations for an airfoil in sinusoidal pitch motion of AOA = ☐.7 showed that it was possible to reduce the amplitude with around 80% from cl = 0.148 to cl = 0.032. Modeling the step response with an indicial function formulation showed that the time constant in the step change and in sinusoidal deflections in dimensionless terms was T0* = 0.6. Testing the airfoil for a step change of the ATEF from = -3.0 to +1.8 showed that the obtainable cl was 0.10 to 0.13 in the linear part of the lift curve. The steady state tests showed that deflecting the ATEF towards the pressure side (positive ) translated the lift curve to higher lift values and deflecting the ATEF towards the suction side (negative ) translated the lift curve to lower lift values. Steady state and dynamic tests were carried out with prescribed deflections of the ATEF. The airfoil was tested at Re = 1.66 × 106. The ATEF was 9% of the total chord, made of piezo electric actuators attached to the trailing edge of a non-deformable airfoil and actuated using an (electric) amplifier.
