Donnet-Denhaut DD-9
__NOTOC__ The Donnet-Denhaut flying boat was a maritime patrol and anti-submarine warfare aircraft produced in France during the First World War. Known at the time simply as "Donnet-Denhaut" or "DD" flying boats, the DD-2, DD-8, DD-9, and DD-10 designations were applied retrospectively to denote the various changes in configuration made during their service life. Design and development Developed in response to a French Navy requirement, these were biplane flying boats of conventional configuration with two-bay unstaggered wings, and a Salmson R9 160 hp radial engine, mounted pusher-fashion on struts in the interplane gap. The French Navy ordered some 90 aircraft in this original configuration (later dubbed DD-2), and in 1917, requested Donnet-Denhaut to redesign the aircraft to take advantage of the new Hispano-Suiza 8 engine. So equipped, the Navy ordered another 365 machines. In order to take full advantage of the more powerful engine, Donnet-Denhaut increased the wingspan ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is also o ...

Flying Boats
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1910s French Patrol Aircraft
Year 191 (Roman numerals, CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

List Of Flying Boats And Floatplanes
The following is a list of seaplanes, which includes floatplanes and flying boats. A seaplane is any airplane that has the capability of landing and taking off from water, while an amphibian is a seaplane which can also operate from land. (They do not include rotorcraft, or ground-effect vehicles which can only skim along close to the water) A flying boat relies on its main hull for buoyancy, while a floatplane has a conventional aircraft fuselage fitted with external floats. In some locales, the term "seaplane" is used as a synonym for floatplane. List A small number of seaplanes have retractable beaching gear, which is not capable of being used for landings and takeoffs, but these remain flying boats or floatplanes and are not amphibians. Many floatplanes, especially those since 1945, can have either conventional floats for operating just from water, or amphibious floats, which have retractable undercarriage built into them. Some experimental flying boats have used skis o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lohner L
The Lohner L was a reconnaissance flying boat produced in Austria-Hungary during World War I. It was a two-bay biplane of typical configuration for the flying boats of the day, with its Pusher configuration, pusher engine mounted on struts in the interplane gap. The pilot and observer sat side by side in an open cockpit, and both the upper and lower sets of wings featured Swept wing, sweepback. Development The design was essentially a more powerful version of the Lohner E, and became highly influential. Apart from licensed production by UFAG, the L provided the basis for designs by other major manufacturers. In Germany, Hansa-Brandenburg manufactured a modified version of it as their first flying boat, the , and in Italy, a captured example was used as a pattern aircraft by Macchi, who produced it as the L.1. In turn, the L.1 would provide the foundation for a large number of Macchi designs over the coming years. The captured aircraft (serial L.40) was taken intact near the nava ...

FBA Type H
The FBA Type H was a French reconnaissance flying boat produced in large numbers in France and Italy during World War I by Franco-British Aviation. Design and development A development of the FBA Type A, the Type H shared the same basic pusher biplane configuration, but was a larger and heavier machine based on a Donnet-Lévêque design and powered by a water-cooled engine in place of the earlier type's rotary. Most French-built Type H aircraft had water-cooled V-8 Hispano-Suiza 8A variants with powers of , though a minority had Lorraine 8Ns. Some Italian built Type Hs also used the higher-power Hispano motor but more had Isotta Fraschini V.4B or engines of the same make, both six-cylinder inlines. The aircraft was a two bay biplane with the smaller span lower wing positioned just above the central fuselage on four supporting struts. There was no stagger and simple parallel interplane struts separated the bays; an extra, outward leaning pair supported the overhanging ...
