Design concepts
-Safe life structure = number of cycles it can make until failure
-Fail safe structure = Multiple load paths (1 fail -> other part will take over until inspection)
-Damage tolerant structure = Large single surface. (1 fail -> surrounding area takes load)
Metals:
-Steel = alloy iron + carbon (strong but heavy)
-Aluminium = mixed, to make stronger (Light, but bad compression and heat resistance)
-Magnesium = Very light, high stiffness. (corrosion sensitive)
-Titanium = perfect! But very expensive
Maintenance
-Line and hangar maintenance
-Hard time maintenance -> time between overhaul (Removal or replacement)
-On condition maintenance -> check the condition (when good enough it isn’t replaced)
-Condition monitoring -> trend following (upper/lower limit)
Construction:
-Monocoque = The skin takes all the loads. Semi-monocoque = reinforced with frames
-Cantilever = self-supporting wing. Non-cantilever = with struts/bracing
