Lioré Et Olivier LeO H-15
The Lioré et Olivier Leo H-15 was a French twelve-seat civil flying boat, flown in a national contest in 1926. It did not win but set two load carrying records, one a world record. Design and development In 1926 the French government offered large prizes in a contest to produce new, multi-engined commercial seaplanes. Compared with similar landplane competitions, few manufacturers offered a candidate; at the trials, held in July and August only the Lioré et Olivier LeO H-15 and the SPCA Météore 63 took part. The LeO H-15 was a three-engined biplane with high aspect ratio, thin section wings of unequal span. The shorter span lower wing, with slight dihedral, was built into the hull and the upper wing was mounted on it without stagger or dihedral. The interplane struts were in parallel pairs, two outward leaning and two vertical outboard, and an interconnected central complex which both braced the wings and mounted two of its three Gnome & Rhône 9Ab nine cylinder ra ...

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 ...

Trailing Edge
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic surface. George Batchelor has written about: :“ ... the remarkable controlling influence exerted by the sharp trailing edge of an aerofoil on the circulation.”Batchelor, G. K. (1967), ''An Introduction to Fluid Dynamics'', p.438, Cambridge University Press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Bristol Jupiter
The Bristol Jupiter was a British nine-cylinder single-row piston radial engine built by the Bristol Aeroplane Company. Originally designed late in World War I and known as the Cosmos Jupiter, a lengthy series of upgrades and developments turned it into one of the finest engines of its era. The Jupiter was widely used on many aircraft designs during the 1920s and 1930s. Thousands of Jupiters of all versions were produced, both by Bristol and abroad under licence. A turbo-supercharged version of the Jupiter known as the Orion suffered development problems and only a small number were produced. The "Orion" name was later re-used by Bristol for an unrelated turboprop engine. Design and development The Jupiter was designed during World War I by Roy Fedden of Brazil Straker and later Cosmos Engineering. The first Jupiter was completed by Brazil Straker in 1918 and featured three carburettors, each one feeding three of the engine's nine cylinders via a spiral deflector housed ins ...
