Fluttle Tool #43

Open EVElove444 opened 1 year ago

How to distinguish which first order mode each line segment represents from the Campbell plot obtained by NUMAD using the Fluttle Tool calculation without a legend?

Sorry to bother you, may I ask if you have a user manual for the BLAST BLade Aeroelastic Stability Tool(BLAST)

Hi HongJieSu, No bother at all. Have seen page 72 of:

Hello, sir, I used BLAST to analyze the flutter of the blades of a 5MW wind turbine. I can't tell the meaning of the lines in the drawing, because the legend information is not given in the drawing. I seek your help. How can I tell whether the flutter has occurred and what is the flutter frequency?  The result is shown in the figure. 222
