Aerodynamics analysis routines for horizontal-axis wind-turbine dynamics analyses.

AeroDyn is an aerodynamics software library (module) for use by designers of
horizontal-axis wind turbines. It is written to be interfaced with a
number of dynamics analysis software packages (such as
FAST, ADAMS, SIMPACK, and FEDEM) for
aero-elastic analysis of wind turbine models. AeroDyn and its downloadable
user's guide assume the user is an experienced wind turbine aerodynamics and dynamics analyst.
The aerodynamics model in AeroDyn is a detailed analysis that
includes blade-element/momentum theory (with modifications to improve
accuracy in yawed flow), dynamic stall, and an optional dynamic inflow
The AirfoilPrep preprocessor
is available to create the input files for the aerodynamics tables in AeroDyn.
TurbSim is also available to create
full-field turbulence for use in AeroDyn.

- AeroDyn Change Log (v13.00.02a-bjj, 38 KB, 22-February-2013)
This is a list of changes made to the code. Look at this text file to
see if we've made worthwhile changes since you received your previous version
of AeroDyn. It is also included in the archive.
- AeroDyn User's Guide (v12.5, 441 KB, 24-December-2002)
This is the AeroDyn User's Guide. It explains what AeroDyn does and how you can use it.
It is also included in the archive. Note: Some of the recent changes to AeroDyn are not included in this guide;
please also read the Addendum to the AeroDyn User's Guide
- AeroDyn Theory Manual (Future version TBD, 1.2 MB, 6-December-2005)
This is the AeroDyn Theory Manual. It describes the algorithms used in the code.
Please note: The algorithms described in the manual are what we intend to have in the routines for a future release.
- AeroDyn Archives (v13.00.02a-bjj)
Both AeroDyn archives contain the AeroDyn source code, change log, user's guide, and sample input files.
If you want to compile the source code, you will also need to download and compile source code from
NWTC Subroutine Library v1.07.00b-mlb and
The archive for Windows® is a self-extracting archive of AeroDyn for PCs.
The archive for Linux is a compressed tar file.
- Addendum to the AeroDyn User's Guide
Because we have not had the time to update the AeroDyn User's Guide, we have temporarily left
AeroDyn v13.00.02a-bjj as an "alpha" version. We have created a document to guide you through the
major changes in the updated code and to document the updated AeroDyn interface. We encourage you to read it.
