Description
Experience Level: Entry
This is in reference to a video at the address of http://www.youtube.com/watch?v=eJn9ks-W8RQ&feature=youtube_gdata_player , where the author explains how to calculate the twist angle of a wind turbine blade.
He is using a tip speed ratio of 8 and a radius of 5m, and I have been calculating using a wind speed of 20m/s because he doesn't state the wind speed.
He states in the following video (part 5) that the Angle Of Inclination at the tip should match the tip speed ratio, meaning AOI should be 8 degrees for a TSR of 8. This makes sense, but for some reason I keep getting an AOI of 7.1!!!
He doesn't show his math so I can't figure it out!
This job is to calculate the Angle Of Inclination for the radius of 5 (the tip), midpoint of the radius, and radius opposite of the tip, and show your math; most importantly how he is calculating an AOI of 8 degrees at the tip
