jpolenek Posted October 13, 2015 Share Posted October 13, 2015 I'm noticing that the top spar cap templates for B.L.52 and B.L.67.5 are slightly curved in addition to being tapered. Is the purpose of this curvature to make the top of the completed spar follow the shape of the airfoil more closely in that area? What's confusing me is that the plans don't mention the curvature, and sections C-C and D-D do not show it either.
