Discussion of the results of a blade deformed

Hi Everybody, I wrote some post earlier about the blade of a wind turbine. Now I would like to share some results I have achieved and I would like to know your opinion about them. For a normal wind (e.g. 10 m/s) I calculated the pressure distribution on the blade. This pressure deforms the blade, an...

Re: Linearisation degree of freedom units and locations

Dear Alec,

the information you need is this PDF, technical and user's manual for the fast_ad advanced dynamics code.

Re: How to simulate special events?

Dear Jason Jonkman, First of all congratulations for this forum, it is very useful. I work at IKERLAN, a research center, and I am studying the deflection failure on the wind turbine blades. We want to analyze the limit behavior of the 5 MW NREL Offshore blade. To develop this simulation we used the...

Re: IECWind

Hi guys, I'm thinking of doing the test according to IEC 61400 standard to see what results we get with our paddle. After reading the IEC 61400 standard, I found a very interesting article in which they made these same test for a blade of 100 meters and they just made those who were critical(The San...

Re: Data for NREL Airfoils

I mean S818 airfoil 30 scaled . As far as I know some airfoils are scaled, I mean, with equal chord (x direction) their y coordinates are farther. I have found S818 27 scaled file, the file which appear the CD and CL coefficient (Aerodyn input) but no 30 scaled. Thank you very much for answering my ...

UPWIND blade materials & geomtry

Hi everybody, First of all congratulations for this forum, it is very useful. I am studying the deflection failure on the wind turbine blades. I have done some analysis in a concrete blade, but I'm thinking about doing the analysis of another blades. The name of the blade is: UPWIND blade (5MW) I ha...

Re: Data for NREL Airfoils

Hi everybody, I am studying the deflection failure on the wind turbine blades. I have done some analysis using ANSYS and matlab programans in order to calculate the blade deflection. FAST is a powerfull tool used in wind turbine calculation, so I want to compare the results with FAST results. But I ...
