They do not fail under static or repeated loads and they do not corrode if the rivets are well chosen and properly set. The designer of an aircraft chooses the solutions best adapted to the materials used - a continuous joint with wood and composites, a single bolt or heavy (thick) fittings with steel or riveted joints on relatively light gauge materials and/or when the joints are long (to avoid the weight penalty of many steel bolts).įor over 50 years, riveted aluminum structures have been very successful, and are found to varying degrees on virtually all aircraft (whether the complete airframe or just an instrument panel). to be carried over from one skin to another, we can choose various ways of achieving this (see figure 1 below). Each of those parts carries a load and the fastener that brings these parts together has to carry the load from one part to the other. Aircraft can't just be made out of one big sheet of material and "wrapped together." Rather, various parts have to be formed out of different types of material and joined together. and still end up with an aircraft of appreciable size, adequate strength and good looks. The designer has to choose materials which are available, can be transported to the manufacturing facility (even the homebuilder's basement or garage), can be cut to required sizes with the minimum tools, and can be handled without causing too many rejects due to mishandling. Aircraft raw materials come in different but limited sizes due to manufacturing limitations as well as economical distribution.
