Aerospace Wing and wind turbine blade aerodynamic center?

Tags:

    Hello everyone,
    Now i am trying to model wind turbine blade using solidworks.

    I have the airfoil coordinates at each section of the blade, but the coordinates are distance per chord (x/c,y/c) so i have to scale it using the calculated chord.
    When i scale it with respect to the origin - which is at the leading edge - the position of the aerodynamic center for each section is changed with respect to others.
    Is the aerodynamic center should be along the same line??
    Is this correct or should i do it another way?
    Thanks in advance.

    Well this has to be the case since the aerodynamic center you were given is the 2D aerodynamic center. The blade's true 3D aerodynamic center will change and will be along a new constant chord. You will have to recalculate the 3D AC or estimate it using CFD.
