Study Notes

Aircraft Structure

Aircraft structures are made up of various components manufactured individually and then joined together.
Common joining methods include adhesives, welds, screws, and rivets.
Rivet joints are non-detachable and are generally used for structural parts that don't require disassembly during maintenance.
Factors considered in selecting a rivet include material type, material thickness of the components being joined, and the rivet's shear strength.

Design of Riveted Joints

Riveted joints are designed so that a single rivet won't fail due to fatigue during normal flight operations.
Fatigue is more likely to affect the structural element before the rivet under dynamic loads.
The fatigue resistance of a rivet joint depends on the spacing between rivets and the number of rivet rows.
In a two-row lap joint, each row carries 50% of the load.
In a three-row joint, the outer rows carry 40% of the load, while the inner row carries 20% of the load.
