The primary body portion of an airplane is called the fuselage (from the French fuselé, meaning “spindle-shaped”). It accommodates personnel, travelers, or freight.
Although in some amphibious aircraft the single engine is installed on a pylon attached to the fuselage, which is then used as a floating hull, in single-engine aircraft it will typically also contain an engine.
Additionally, the fuselage positions the control and stabilization surfaces in relation to the lifting surfaces, which is necessary for the stability and maneuverability of the aircraft. Wood can also be used to construct a box truss fuselage, which is frequently covered in plywood.
By adding supported lightweight stringers to plain box structures, the corners can be softened, giving the fabric covering a more aesthetically appealing or aerodynamic shape.
The outside surface of the fuselage serves as both the main structure and the monocoque shell technique. Molded plywood was used to construct a typical early version of this (the Lockheed Vega), where the layers of plywood are created over a “plug” or inside a mold.
A subsequent version of this construction substitutes fiberglass cloth for plywood as the skin and coats it with polyester or epoxy resin. A straightforward version of this is used in some homebuilt aircraft as the hard expanded foam plastic core, covered in fiberglass. This eliminates the need to create molds but adds extra finishing work.
The World War II de Havilland Mosquito fighter/light bomber is an illustration of a larger molded plywood aircraft. Since stiffening features are built into the structure to support concentrated loads that would otherwise cause the thin plywood skin to buckle, no plywood-skin fuselage is really monocoque.
In the mass manufacture of many contemporary sailplanes, molded fiberglass employing negative (“female”) molds (which results in a virtually finished product) is common.
Large passenger planes like the Boeing 787 Dreamliner are being made to utilize molded composites for the fuselage structures (using pressure molding on female molds).
The Global Fuselage refueling units market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
For receiving aircraft with probes, Eaton’s fuselage refueling equipment, also known as hose drum units, offers center-line refueling. A faster fuel dumping rate and more space for larger aircraft and rotorcraft are two additional advantages of the most recent generation of fuselage refueling units over wing pods.
Tankers with multi-point hose and drogue systems, including a fuselage refueling unit, provide them more flexibility and let two aircraft refuel at once, cutting down on the amount of time they need to be on station.
Systems for refueling hoses and drogues that are extremely dependable and simple to maintain can be created by integrating the internal hose drum’s electrical, hydraulic, and fuel subsystems.
