Which type of fuselage is characterized by a rigid framework of members?

A truss fuselage is characterized by its rigid framework, which consists of a series of interconnected members that form a supportive structure. This design uses triangular shapes to distribute loads efficiently, making it strong and lightweight. The interconnected members, often made from materials like steel or aluminum, create a sturdy skeleton that can support the various loads experienced in flight.

This design is advantageous because it allows for a high strength-to-weight ratio, making truss fuselages commonly used in smaller aircraft and some military planes. The structure is generally easy to repair and modify since the individual components can be accessed and replaced without significant disruption to the overall design.

In contrast, a monocoque fuselage relies on the external skin to carry loads, which limits the internal framework. The semimonocoque variation includes a reinforced skin with some internal structure but is not as rigidly defined as the truss. Composite fuselages utilize advanced materials such as carbon fiber, which provides different structural benefits but does not inherently emphasize the rigid framework characteristic of a truss design.
