The blade is 27m long with a rotational angular velocity of 2.43 rad/s. The upstream wind speed (or should we say the free stream velocity?) is 8 m/s. The blade is made out of an orthotropic composite material with the following properties:
Density | 1550 Density (kg/m^3) | 1550 |
---|---|---|
Young's Modulus-X (Pa) | 1.1375E+11 Pa | |
Young's Modulus-Y (Pa) | 7.583E+09 Pa | |
Young's Modulus-Z (Pa) | 7.583E+09 Pa | |
Poisson's Ratio-XY | 0.32 | |
Poisson's Ratio-YZ | 0.37 | |
Poisson's Ratio-XZ | 0.35 | |
Shear Modulus-XY (Pa) | 5.446E+09 Pa | |
Shear Modulus-YZ (Pa) | 2.964E+09 Pa | |
