She also flies a Pulsar.
Glad to have such person alive on HBA.
Thanks. We have this as turning point on all our discussion, but in opposite result - single skin will buckle due torsional load if not divided into many small shear cells..If all plies are on the outside in the wing skin, the torsional stiffness is greater than that of a sandwich skin.
I am a bit reluctant to answer this one because some may take this as an incentive to use the same ply schedule for their airplane.And skin thickness ?
Thank you. No, i am looking for freebie up here. I did done some fea runs, to find how good/bad is single skin compared to foamed one. Here are some examples :I am a bit reluctant to answer this one because some may take this as an incentive to use the same ply schedule for their airplane.
Caro's wing skin layup is applicable to only this plane and its loads.
I have 2-4 plies at 45 deg of 5.7 oz/sqyd carbon in the wing skins. It varies spanwise and chordwise.
It does not sag between ribs and stiffeners and has maintained its contour well in the >5 years since I built it.
