On some nacelle panels there is a surfacer, aluminum mesh, fiberglass ply, and then graphite... With aluminum fittings bolted on the inside of the graphite, but there is an island of fiberglass under each fitting. That's interesting. How does it compare weight-wise to copper without a fiberglass interface ply? Quote
KSMooniac Posted December 18, 2019 Report Posted December 18, 2019 That's interesting. How does it compare weight-wise to copper without a fiberglass interface ply? I'm not sure, but vaguely remember in service concerns with copper corrosion fouling the paint, but I could be mistaken. The 787 fuselage has interwoven copper so I guess they figured out a way to make it work, and last.Sent from my LG-US996 using Tapatalk 1 Quote

Beautiful work. Does this include removing the rumored inboard flat spot on the top of the airfoil? Dang you guys are good! The skin was basically low over all of the stringers and it was very low over the spar. So instead of being the perfect shape that Al designed it’s kind of a series of high and low bands from front to back. The rivet dimples on the spar were .030” deep. The outboard wing skin was flat to the spar then kinked over it then flat behind it. We fixed all that. We use profilimeter to measure this, as long as the wing camber keeps getting flatter as you go back then the wing doesn’t have any low spots. Factory sprays something like Featherfill which is like Bondo out of a spray gun and they block it flat and paint it. But this is a cheap fast and not that really good way of doing this 2 Quote

Blue on Top Posted December 18, 2019 Report Posted December 18, 2019 @jetdriven YOU are just so freakin' cool!!!!!!!! Way cool work. I'm excited for you, and hope you find really positive results. A small note of irony (and I am sarcastically laughing about this, sorry): As one watches the video (as I did over and over), where was this airplane made? 1 Quote
