Loire-Nieuport LN.30
The SNCAO 30 was a French single-engined monoplane flying boat two-seat trainer. Although it was ordered into production for the French Navy, only two prototypes were built. Development and design In the late 1930s Loire-Nieuport commenced development of the Loire-Nieuport LN-30 as a private venture to meet a requirement of the French Navy for a two-seat flying boat trainer. The resultant design, which was renamed SNCAO 30 when Loire-Nieuport was nationalised and became part of Société nationale des constructions aéronautiques de l'ouest (SNCAO), was a single-engined pusher monoplane of wooden construction, with the crew of two sitting side-by side in an open cockpit. Its wing was carried on struts above the fuselage, with the Salmson 9ABa radial engine mounted above the wing.Green 1968, p.20. The first prototype, built at the SNCAO factory at Saint Nazaire, made its maiden flight on 13 September 1938, these resulting in a number of modifications, including adding di ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External Bracing (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

SNCAO Aircraft
SNCAO (abbreviated from ''Société nationale des constructions aéronautiques de l'ouest'') was a state-owned French aircraft manufacturer, which originated on November 16, 1936, from the merger of the factories of Breguet in Bouguenais, and Loire-Nieuport in St Nazaire and Issy-les-Moulineaux. The company had been formed as one of six state-owned ''Société Nationales'' in the 1936 nationalistation of military industries; at the end of 1940 these were re-organised and SNCAO was absorbed by SNCASO. In 1957 SNCASO was merged into Sud Aviation.

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] |
1930s French Military Trainer Aircraft
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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] |
Loire 130
The Loire 130 was a French flying boat that saw service during World War II. It was designed and built by Loire Aviation of St Nazaire. Development The Loire 130 originated from a mid-1930s requirement from the French Navy for a reconnaissance seaplane or flying boat that could also serve aboard French battleships and cruisers. Chosen in 1936 against five competitors ( Bréguet 610, Gourdou-Leseurre GL-820 HY, Levasseur PL.200, Potez CAMS 120), the Loire 130's performance was deemed to be good and production orders for 150 of the machines were placed. It entered production in 1937 and replaced most shipborne seaplanes and flying boats already in service. Operational service In the late 1930s, Loire 130s were serving aboard most battleships and cruisers of the French Navy, as well as aboard the seaplane tender ''Commandant Teste''. Although appearing quite obsolete and having very marginal performance for their time, quite a few Loire 130s survived the war and remained in post-w ...

Twin Tail
A twin tail is a specific type of vertical stabilizer arrangement found on the empennage of some aircraft. Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer. This arrangement is also known as an H-tail,Schiff, Barry: ''Flying'', page 15. Golden Press, New York, 1971. Library of Congress 78-103424 as it resembles a capital "H" when viewed from the rear. The twin tail was used on a wide variety of World War II multi-engine designs that saw mass production, especially on the American B-24 Liberator and B-25 Mitchell bombers, the British Avro Lancaster and Handley Page Halifax heavy bombers, and the Soviet Union's Petlyakov Pe-2 attack bomber. Variations on the twin tail include the triple tail, twin boom tail and double tail. Design Separating the control surfaces allows for additional rudder area or vertical surface without requiring a massive single tail. On m ...

Dihedral (aircraft)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Nazaire
Saint-Nazaire (; ; Gallo language, Gallo: ''Saint-Nazère/Saint-Nazaer'') is a Communes of France, commune in the Loire-Atlantique Departments of France, department in western France, in traditional Brittany. The town has a major harbour on the right bank of the Loire estuary, near the Atlantic Ocean. The town is at the south of the second-largest swamp in France, called "la Brière". Given its location, Saint-Nazaire has a long tradition of fishing and shipbuilding. The Chantiers de l'Atlantique, one of the largest shipyards in the world, constructed notable ocean liners such as , , and the cruise ship , the largest passenger ship in the world until 2022. Saint-Nazaire was a small village until the industrial era, Industrial Revolution but became a large town in the second half of the 19th century, thanks to the construction of railways and the growth of the seaport. Saint-Nazaire progressively replaced upstream Nantes as the main haven on the Loire estuary. As a major submari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
