Wing spar location

  1. Feb 2, 2014 #1
    Hi, I wonder where is the best location for a wing spar thorugh its cord. Up to where I know it is on the Aerodynamic center (approximately 1/4 of the chord from the leading edge) because is the point on the chord where the lift acts. I am using a 17in chord S1223 airfoil.

    The best location for a wing spar is where the airfoil is thickest. The strength of a given spar is proportional to the square of the depth of the spar. That's basic strength of materials.
