Bloch 175
The Bloch MB.170 and its derivatives were French reconnaissance bombers designed and built shortly before the Second World War. They were the best aircraft of this type available to the at the outbreak of the war, with speed, altitude and manoeuvrability that allowed them to evade interception by the German fighters. Although the aircraft could have been in service by 1937, debate over what role to give the aircraft delayed deliveries until 1940. Too few in number to affect the Battle of France, they continued in service with the Vichy forces after the armistice. The MB.174 is notable as the aircraft flown by Antoine de Saint-Exupéry, author of ''The Little Prince'' during the campaign. His work (''Flight to Arras''), published in 1942, is based on a 1940 reconnaissance mission in this type of aircraft. Design and development In 1936, the Ministry for the Air initiated a programme of modernisation of French aviation which included a request concerning a two- or three-seat mu ...

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".

Vichy France
Vichy France (french: Régime de Vichy; 10 July 1940 – 9 August 1944), officially the French State ('), was the fascist French state headed by Marshal Philippe Pétain during World War II. Officially independent, but with half of its territory occupied under harsh terms of the armistice, it adopted a policy of collaboration with Nazi Germany, which occupied the northern and western portions before occupying the remainder of Metropolitan France in November 1942. Though Paris was ostensibly its capital, the collaborationist Vichy government established itself in the resort town of Vichy in the unoccupied "Free Zone" (), where it remained responsible for the civil administration of France as well as its colonies. The Third French Republic had begun the war in September 1939 on the side of the Allies. On 10 May 1940, it was invaded by Nazi Germany. The German Army rapidly broke through the Allied lines by bypassing the highly fortified Maginot Line and invading through ...

Bomb Bay
The bomb bay or weapons bay on some military aircraft is a compartment to carry bombs, usually in the aircraft's fuselage, with "bomb bay doors" which open at the bottom. The bomb bay doors are opened and the bombs are dropped when over the target or at a specified launching point. History and function Bomb bays were born of necessity. Early military aircraft suffered severe aerodynamic drag (which would further slow down the already lumbering bomb-laden aircraft) with bombs hanging from the wings or below the fuselage, so military aviation designers moved the bombs inside the aircraft. Before the introduction of stealth technology bomb bays were mostly used by dedicated bomber aircraft; in fighters and attack airplanes bombs and rockets were hung from the wings or fuselage on pylons. Notable exceptions are the F-101, F-102 and F-106 interceptor aircraft, all of which had bays used to store missiles, or other weapons stores. Today many designers have moved previously "e ...

MAC 1934
The MAC 1934 is a machine gun of French origin. It is effectively the aircraft variant of the Reibel machine gun. History In 1934, the ''Manufacture d'Armes de Châtellerault'' (Châtellerault weapons manufacturing company, often shortened to ''MAC'') completed the development of the MAC 1934 machine gun to replace the Darne mod. 1933 machine gun aboard aircraft of the ''Armée de l'Air''. Essentially a faster-firing variant of the mitrailleuse mle 1931, and using the same 7.5 mm MAS ammunition, the MAC 34 worked by gas operation and was fed from drum magazines. Two main variants, sharing common parts, were introduced: * the ''type tourelle'' (turret model), fed from 100-round replaceable magazines, was used in flexible mountings, where it was generally fitted with an Alkan 1935 reflector gunsight. * the ''type aile'' (wing model) fed from a 300- or 500-round drum magazine, was used for fixed mountings. Because it used an open bolt action, the MAC 34 could not be fitted with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Gnome-Rhône 14N
The Gnome-Rhône 14N was a 14-cylinder two-row air-cooled radial engine designed and manufactured by Gnome-Rhône just before the start of World War II. A development of the Gnome-Rhône 14K, the 14N was used on several French and even one German aircraft. Design and development The 14K's reliability was poor, so Gnome-Rhône carried out major redesign, using different materials for the pistons and valves, and enlarging the cooling fins to increase surface area by 39%. The 14N was introduced in 1937 and was quickly installed on several aircraft models. In 1939, minor improvements allowed Gnome-Rhône to increase the compression ratio from 6.1:1 to 6.8:1, which increased power. The 14N was further developed into the Gnome-Rhône 14R featuring a 2-stage supercharger, but this type was not widely used until after World War II as production of improved engines was restricted by the armistice with Germany.

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of 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 can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

SNCASO
SNCASO (abbreviated from ''Société nationale des constructions aéronautiques du Sud-Ouest'', or commonly, ''Sud-Ouest'') was a French aircraft manufacturer. Created during 1936 as one of seven nationalised aeronautical manufacturing companies, SNCASO became a key French aircraft manufacturer following the end of the Second World War. It produced numerous innovation aircraft; amongst the company's more notable projects was the first French jet aircraft, the Sud-Ouest Triton, and the first indigenously-developed French helicopter, the Sud-Ouest Djinn. On 1 March 1957, SNCASO merged with another French nationalised aviation company, SNCASE, (''Société nationale des constructions aéronautiques du Sud-Est''), to form Sud Aviation. History Following the resolution of the 1936 general strike of French heavy industry, the government of Léon Blum introduced an act to nationalize the French war industry. The act provided for the creation of seven nationalised aeronautical manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Courbevoie
Courbevoie () is a commune located in the Hauts-de-Seine Department of the Île-de-France region of France. It is in the suburbs of the city of Paris, from the center of Paris. The centre of Courbevoie is situated from the city limits of Paris. La Défense, a business district hosting the tallest buildings in the metropolitan area, spreads over the southern part of Courbevoie (as well as parts of Puteaux and Nanterre). Name The name Courbevoie comes from Latin ''Curva Via'' and means "curved highway", allegedly in reference to a Roman road from Paris to Normandy that made a sharp turn to climb the hill over which Courbevoie was built. Administration Courbevoie is divided into two cantons: Canton of Courbevoie-1 and Canton of Courbevoie-2. History A wooden bridge was built crossing the Seine at Courbevoie by order of King Henry IV when in 1606 his royal coach fell into the river while being transported by ferry. Rebuilt in stone during the eighteenth century, this w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
