Quick Summary

A monocoque is a type of construction where the outer skin carries most of the stresses. This contrasts with earlier aircraft designs that relied on internal bracing and external wires for structural strength.12

In aircraft, monocoque construction involves using the fuselage's skin to bear the load, leading to greater strength, better streamlining, and lighter weight. This method was adopted by some manufacturers as aircraft speeds increased. A related structure, the semimonocoque, is similar but reinforced with longitudinal stringers. Early aircraft were typically made of wood and fabric, but the need for greater strength and durability led to the use of metal, including all-metal monocoque designs.132
