Where S.T.E.M. Takes Flight FUSELAGE TYPES 1  FIXED WING AIRCRAFT FUSELAGE The fuselage is the main structure or body of the fixed-wing aircraft. It provides space for cargo, controls, accessories, passengers, and other equipment. There are two general types of fuselage construction: 1) Truss and 2) Monocoque. WHERE S.T.E.M.

The truss-framed fuselage is generally covered with fabric. The modern truss-type fuselage frame is usually constructed of steel. WHERE S.T.E.M.

The design may be divided into two classes: 1. Monocoque 2. Semimonocoque WHERE S.T.E.M.

Thus, the biggest problem involved in monocoque construction is maintaining enough strength while keeping the weight within allowable limits. WHERE S.T.E.M.

It also consists of frame assemblies, bulkheads, and formers as used in the monocoque design but, additionally, the skin is reinforced by longitudinal members called longerons. Longerons usually extend across several frame members and help the skin support primary bending loads. WHERE S.T.E.M.
