52-573: A rigid fixture . These formers are then joined with lightweight longitudinal elements called stringers . These are in turn covered with a skin of sheet aluminum, attached by riveting or by bonding with special adhesives. The fixture is then disassembled and removed from the completed fuselage shell, which is then fitted out with wiring, controls, and interior equipment such as seats and luggage bins. Most modern large aircraft are built using this technique, but use several large sections constructed in this fashion which are then joined with fasteners to form

78-485: A design is intended to be "self jigging", not requiring a complete fixture for alignment. Early aircraft were constructed of wood frames covered in fabric. As monoplanes became popular, metal frames improved the strength, which eventually led to all-metal-structure aircraft, with metal covering for all its exterior surfaces - this was first pioneered in the second half of 1915 . Some modern aircraft are constructed with composite materials for major control surfaces, wings, or

104-465: A large warplane which uses this process). The logical evolution of this is the creation of fuselages using molded plywood, in which several sheets are laid with the grain in differing directions to give the monocoque type below. In this method, the exterior surface of the fuselage is also the primary structure. A typical early form of this (see the Lockheed Vega ) was built using molded plywood , where

130-447: A portion of the external load (i.e. from wings and empennage, and from discrete masses such as the engine) is taken by the surface covering. In addition, all the load from internal pressurization is carried (as skin tension ) by the external skin. The proportioning of loads between the components is a design choice dictated largely by the dimensions, strength, and elasticity of the components available for construction and whether or not

156-528: A scratch pane near the passenger. Acrylic is susceptible to crazing  : a network of fine cracks appears but can be polished to restore optical transparency , removal and polishing typically undergo every 2–3 years for uncoated windows. " Flying wing " aircraft, such as the Northrop YB-49 Flying Wing and the Northrop B-2 Spirit bomber have no separate fuselage; instead what would be

182-445: Is composed of 4–6 panels, 35 kg (77 lb) each on an Airbus A320 . In its lifetime, an average aircraft goes through three or four windshields , and the market is shared evenly between OEM and higher margins aftermarket . Cabin windows, made from much lighter than glass stretched acrylic glass , consists of multiple panes: an outer one built to support four times the maximum cabin pressure, an inner one for redundancy and

208-446: Is different from Wikidata All article disambiguation pages All disambiguation pages Curtiss F8C Helldiver U.S. Navy variants were used initially as fighter-bombers with the designation F8C Falcon , then as the first U.S. Marine Corps dive bombers with the name Helldiver . Two later generations of Curtiss dive-bombers were also named Helldiver . The type was introduced in 1925 and saw first-line service in

234-465: Is prevalent in the series production of many modern sailplanes . The use of molded composites for fuselage structures is being extended to large passenger aircraft such as the Boeing 787 Dreamliner (using pressure-molding on female molds). This is the preferred method of constructing an all- aluminum fuselage. First, a series of formers in the shape of the fuselage cross sections are held in position on

260-427: Is required for aircraft stability and maneuverability. This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to

286-671: The 9th Observation Group , Mitchel Field , New York . The A-3 Attack Falcon saw considerable use, in first-line service with the 8th, 13th and 19th Attack Squadrons of the 3rd Attack Group, Barksdale Field , Louisiana , and the 26th Attack Squadron in Hawaii from 1928 to 1934 and second-line service with reserve units until 1937. The U.S. Navy introduced the F8C-1 and F8C-3 Falcon as a shipboard fighter in 1927–1928. They were later redesignated OC-1 and OC-2 for Marine Corps use as an observation/bomber. The F8C-4 Helldiver variant initially saw service with

312-720: The Brazil Constitutionalist Revolution of 1932, under the flag of São Paulo . In Bolivia , the aircraft type also fought in the Chaco War (1932–1935), bombing Paraguayan troops. The Colombian Air Force used Falcon F-8 and O-1 in the Colombia-Peru War in 1932–3.

338-524: The French fuselé "spindle-shaped") is an aircraft 's main body section. It holds crew , passengers, or cargo . In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull . The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces , which

364-529: The O-1 ordered by the Army was fitted with the 435 hp (324 kW) Curtiss V-1150 (D-12) engine. The aircraft was a conventional unequal-span biplane design with wooden wings, while the fuselage was built using aluminum tubing with steel tie rod bracing. The landing gear was fixed and the tail included a balanced rudder with a rear skid originally, later changed to a tailwheel. The initial A-3 Falcon order

390-474: The Rutan VariEze ). An example of a larger molded plywood aircraft is the de Havilland Mosquito fighter/light bomber of World War II . No plywood-skin fuselage is truly monocoque , since stiffening elements are incorporated into the structure to carry concentrated loads that would otherwise buckle the thin skin. The use of molded fiberglass using negative ("female") molds (which give a nearly finished product)

416-796: The Navy, and the first production batch of 25 was transferred in 1931 to the Marine Corps. A total of 34 F8Cs redesignated as O2C-1 observation aircraft were also transferred to the Naval Reserve in 1931, serving with squadrons VN-10RD9, VN-11RD9, and VN-12RD9. Most of the 63 newer F8C-5/O2C-1 Helldivers also served with the Marines, remaining in service until 1936. The type was featured in multiple Hollywood films: Flight (1929), Hell Divers (1932) and King Kong (1933). Two non-flying replicas were built for King Kong (2005) Curtiss Falcon aircraft fought during

442-788: The United States until 1934. Curtiss Falcons fought in the Constitutionalist Revolution of 1932 in Brazil , used by the forces of São Paulo . The Falcon XO-1 prototype was evaluated by the USAAC along with eleven other prototypes in 1924 and the Douglas XO-2 was declared the winner of that competition. So Curtiss re-engined the prototype with the Packard 1A-1500 for the 1925 trials, which it won. The engine failed to live up to expectations and

468-541: The advantage of being made almost entirely of wood. A similar construction using aluminum alloy was used in the Vickers Warwick with less material than would be required for other structural types. The geodesic structure is also redundant and so can survive localized damage without catastrophic failure. A fabric covering over the structure completed the aerodynamic shell (see the Vickers Wellington for an example of

494-616: The complete fuselage. As the accuracy of the final product is determined largely by the costly fixture, this form is suitable for series production, where many identical aircraft are to be produced. Early examples of this type include the Douglas Aircraft DC-2 and DC-3 civil aircraft and the Boeing B-17 Flying Fortress . Most metal light aircraft are constructed using this process. Both monocoque and semi-monocoque are referred to as "stressed skin" structures as all or

520-631: The entire fuselage such as the Boeing 787. On the 787, it makes possible higher pressurization levels and larger windows for passenger comfort as well as lower weight to reduce operating costs. The Boeing 787 weighs 1,500 lb (680 kg) less than if it were an all-aluminum assembly. Cockpit windshields on the Airbus A320 must withstand bird strikes up to 350 kn (650 km/h) and are made of chemically strengthened glass . They are usually composed of three layers or plies, of glass or plastic :

546-402: The eye. Geodesic structural elements were used by Barnes Wallis for British Vickers between the wars and into World War II to form the whole of the fuselage, including its aerodynamic shape. In this type of construction multiple flat strip stringers are wound about the formers in opposite spiral directions, forming a basket-like appearance. This proved to be light, strong, and rigid and had

572-485: The fuselage is a thickened portion of the wing structure. Conversely, there have been a small number of aircraft designs which have no separate wing, but use the fuselage to generate lift. Examples include National Aeronautics and Space Administration 's experimental lifting body designs and the Vought XF5U-1 Flying Flapjack . A blended wing body can be considered a mixture of the above. It carries

598-634: The inner two are 8 mm (0.3 in.) thick each and are structural, while the outer ply, about 3 mm thick, is a barrier against foreign object damage and abrasion , with often a hydrophobic coating. It must prevent fogging inside the cabin and de-ice from −50 °C (−58 °F). This was previously done with thin wires similar to a rear car window but is now accomplished with a transparent, nanometers-thick coating of indium tin oxide sitting between plies, electrically conductive and thus transmitting heat. Curved glass improves aerodynamics but sight criteria also needs larger panes. A cockpit windshield

624-420: The layers of plywood are formed over a "plug" or within a mold . A later form of this structure uses fiberglass cloth impregnated with polyester or epoxy resin as the skin, instead of plywood. A simple form of this used in some amateur-built aircraft uses rigid expanded foam plastic as the core, with a fiberglass covering, eliminating the necessity of fabricating molds, but requiring more effort in finishing (see

676-543: Was placed in the winter of 1927 and delivery of the first plane was in October 1927. A total of 76 A-3s were received. Later, six aircraft were modified as pilot trainers with dual controls and redesignated A-3A. A second batch of 78 improved A-3Bs, based on the Curtiss O-1E, was purchased beginning in 1929. Reasonably successful as an observation aircraft, Falcons flew primarily in the 1st , 5th and 99th Observation Squadrons of
