hello to all,
am designing a turbine blade using xfoil. i have done all the necessary calculation including the average wind speed of the site i selected and the airfoil analysis for the aifoils i am using now. am using the mh airfoil. they are mh102, mh104, mh106, mh10, mh110. am using this 5 airfoils along the blade. when i analysed these airfoils in xfoil i got the polars and used it to make a graphical representation so i could find the CL, ALFA, CD, L/D for each airfoil. now my blade r/R, c/R, r and c has been calculated. now what am finding difficult in calculating is the blade setting angles with respect to r. and also can can somebody tell if my approach is correct. hoping u will help me, thanks
details: R=10m, r=0.4, average speed is 6.3m/s, tsr=7
