I am at the 40% of my load test of the Aluminum Dragon. The total weight is 698 lb. on the LH wing for 5.33 Gs......The current weight loaded is 279 lb. which translate to 2.1 G..... I am getting serious oil canning on the buckling side (lower side) of the leading edge. The web and caps are not wrinkling or buckling. Is this normal, should I add span wise stiffeners to the first two bays.? I was taught the spar handles the bending. I may have reached my Peter Principal here.
When I remove the weight there is no permanent deformation (yet).
Shown sand bags in 10% increments. 20% to 100% Tractor jack to lessen tire deflection. Pictures of the leading edge deformation.
