Quick Summary

A semimonocoque is a type of stressed-skin structure used for airplane fuselages. It differs from a monocoque by incorporating longitudinal stringers for reinforcement. The fuselage is the central body of an airplane, housing the crew, passengers, and cargo.12

In aircraft construction, both monocoque and semimonocoque designs offer superior strength-to-weight ratios compared to older truss-type constructions. A monocoque structure is one where the outer skin bears most or all of the stresses. The semimonocoque adds stringers to this stressed skin, providing additional support and strength.231
