CCBlade

A blade element momentum method for analyzing wind turbine aerodynamic performance that is robust (guaranteed convergence), fast (superlinear convergence rate), and smooth (continuously differentiable). Analytic gradients are also (optionally) provided for the distributed loads, thrust, torque, and power with respect to design variables of interest.

Prerequisites

Fortran compiler, NumPy, SciPy, zope.interface

Installation

Install CCBlade with the following command.

$ python setup.py install

Note that the installation also includes AirfoilPrep.py. Though not strictly necessary to use with CCBlade, it is convenient when working with AeroDyn input files or doing any aerodynamic preprocessing of airfoil data.

Run Unit Tests

To check if installation was successful, run the unit tests

$ python test/test_ccblade.py
$ python test/test_gradients.py
