### Re: Help about BEM and NREL's Phase VI

By the way, are there any data concerning the tip deflection of NREL's Phase VI similar to this,

### Re: Help about BEM and NREL's Phase VI

Dear Wesley, I'm not sure I really understand your question, but in FAST/AreoDyn, the local angle of the chordline from the rotor plane (theta), is the sum of the blade-pitch angle (theta_p) and the local blade-twist angle (theta_t), the latter of which includes both aerodynamic twist and elastic (...

### Re: Help about BEM and NREL's Phase VI

Sir, got a new question.. I've read somewhere in this forum (re: NREL Phase VI), about the tip pitch angle (3 degrees) and section pitch angle, (around 4.815 degrees). I've read from the book of Manwell et al., (2009) that the formula for twist angle is section PA - blade PA at the tip. The twist an...

### Re: Help about BEM and NREL's Phase VI

Oh, my apologies sir. and thanks for replying :)) sir, I'll start with the BEM iteration, if I will use 6 m/s as free stream velocity, when the BEM iteration converges, the power computed is 19.8kW? Or the 6 m/s only indicates that this is the cut-in speed? I've seen several studies that used more t...

### Help about BEM and NREL's Phase VI

First of all, thank you for the opportunity to be a member of this forum. :) I'm currently doing an iteration in Excel about NREL's Phase VI wind turbine for validation purposes. I tried using 6 m/s as the free stream velocity and the radial sections selected (Fig 1) are attached on this post. Howev...
