# Wind Turbine Blade Optimization. This example shows how to adjust the twist and chord length along a wind turbine blade to optimize the power output. It combines a Simscape™ Driveline™ test harness model with the `fminsearch` optimization function. % Initial value for angle of attack [rad]% Number of blades [-] % Number of radial sections to optimize % Initialize vectors% Vector of initial value for twist [deg]% Vector of initial value for chord length [m] for% Local tip speed ratio [-]% Angle of relative twist [rad]% [deg]% Lift coefficient [-]% [m] end % Set twist at round root equal to neighboring twist % Adjust twist based on maximum permitted change in twist between radial sections% Maximum permitted change in twist between radial sections [deg] for if elseif end end % Limits to chord% Maximum permitted chord length [m]% Minimum permitted chord length [m] % Assign maximum permitted chord to the root % Limit the chord lengths % Plot the initial twist and chord lengths"Twist (deg)""Radius (m)" "Initial Blade Twist".

For articles published under an open access Creative Common CC BY license, any part of the article may be reused without permission provided that the original article is clearly cited. Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. The optimization framework integrates DAFoam as the computational fluid dynamics (CFD) solver, TACS as the finite element method (FEM) solver, Mphys for fluid–structure coupling, and SNOPT as the optimizer within the OpenMDAO framework. The design variables in this optimization process are the blade shape and panel thickness. The remainder of this paper starts with a literature review on the aerostructural optimization of wind turbine blades in Section 2, followed by the methodology on the aerodynamic optimization, structural optimization, and fluid–structural coupling processes of the aerostructural optimization in Section 3, and the main findings are presented and discussed in Section 4.

This is part 3 of my series: “How Does a Wind Turbine Work?” In this video I show you how to use the blade element momentum theory, BEM, that we discussed in the last videos, to design an efficient wind turbine rotor.
Topics include:
00:33 Lift equation
00:47 Optimum aerodynamic conditions with constant circulation along the span
01:05 How the local wind speed and angle vary along the length of the blade
01:22 How to change the chord and twist angle along the blade span
01:50 Why designers normally modify the chord distribution to have smaller chords at the root
02:28 The torque equation and why the tip's aerodynamics is more important than the root
02:52 What happens if you use a turbine at a different wind speed than it was designed for
03:46 How variable speed turbines can operate efficiently over a wind range of wind speeds
04:18 What is tip speed ratio (TSR) and why is it important to wind turbine designers?
04:48 Blade solidity
06:07 How to find a starting point in the wind turbine blade design process
07:22 Why are wind turbine blades getting so skinny?
07:54 Reducing wind turbine noise by limiting rotational speed
08:29The different requirements of aerofoils at the root versus tip of the blade
Check out part one and two of my “How Does a Wind Turbine Work?” series where I go through the mechanical engineering and aerodynamic theory needed to understand how a wind turbine works and design a wind turbine blade:

The optimum aerodynamic design equation at 6:10 has the following parameters:
sigma_r = chord solidity at the radial location (chord length divided by swept circumference at that radial location)
lambda = tip speed ratio (tip speed due to blade rotation (radial location times rotational speed) divided by wind speed)
C_l = local lift coefficient
mu = r/R (radial location divided by radius)
