Potez 220
The Potez 220 was a prototype French twin-engined, three-seat reconnaissance and army cooperation aircraft. Two examples were built in 1939, but no production followed. Design and development On 6 February 1937, the French air ministry issued specification A.24 for a three-seat reconnaissance and army-cooperation aircraft.Green 1967, p. 64. To meet this requirement, the nationalised Société Nationale de Constructions Aéronautiques du Nord ( SNCAN), formed in January 1937 from ANF Les Mureaux, Potez, Chantiers Aéro-Maritimes de la Seine and parts of Breguet and Amiot,Gunston 2005, p. 337. gave the task to the design team inherited from Les Mureaux. Their design, the Potez 220 was a twin-engined monoplane of all-metal construction. The fuselage was an oval-section monocoque, which accommodated the aircraft's crew of three, consisting of a pilot, a radio operator gunner and an observer, with a glazed gondola slung under the fuselage provided for the observer. It was powered b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which ...

Potez Aircraft
Potez (pronounced ) was a French aircraft manufacturer founded as Aéroplanes Henry Potez by Henry Potez at Aubervilliers in 1919. The firm began by refurbishing war-surplus SEA IV aircraft, but was soon building new examples of an improved version, the Potez SEA VII. History During the inter-war years, Potez built a range of small passenger aircraft and a series of military reconnaissance biplanes that were also licence-built in Poland. In 1933, the firm bought flying boat manufacturer CAMS. The company was nationalized in 1936, following which it was merged with Chantiers aéronavals Étienne Romano, Lioré et Olivier, CAMS and SPCA in order to form the Société nationale des constructions aéronautiques du Sud-Est (SNCASE) on 1 February 1937. Potez's factories in Sartrouville and Méaulte were taken over by SNCAN and the Berre factory went to SNCASE. After World War II, Potez was re-established as Société des Avions et Moteurs Henry Potez at Argenteuil but did not re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1930s French Military Reconnaissance 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.

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] |
Martin Maryland
The Martin Model 167 Maryland was an American medium bomber that first flew in 1939. It saw action in World War II with France and the United Kingdom. Design and development In response to a December 1937 United States Army Air Corps requirement for an attack aircraft capable of carrying a bombload of over a range of at a speed of , the Glenn L. Martin Company produced its Model 167, which was given the official designation XA-22, competing with designs from Bell Aircraft (the Model 9), Douglas (the Douglas DB-7), North American (the NA-40) and Stearman (the Stearman XA-21). Martin's design was a twin-engine all-metal monoplane, capable of around 310 mph (500 km/h) with a crew of three. The XA-22 was not adopted for operational service in the U.S., because the contract was won by the Douglas DB-7, which became the A-20 Havoc, but Martin received foreign orders, and about 450 of the fast, twin-engined bombers were built. The prototype Model 167W was powered by twin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloch 174
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-se ...

Potez 63
The Potez 630 and its derivatives were a family of twin-engined, multirole aircraft developed for the French Air Force in the late 1930s. The design was a contemporary of the British Bristol Blenheim (which was larger and designed purely as a bomber) and the German Messerschmitt Bf 110 (which was designed purely as a fighter). The Potez 630 was in use by several operators during the Second World War. Following the Battle of France, both the Vichy French Air Force and Free French Air Forces used the type; a number of captured aircraft were operated by several air wings of the Axis powers. After the end of the conflict in 1945, a handful of aircraft were used for training purposes for some time. Development Origins On 31 October 1934, the French Ministry of Air issued a specification for a heavy fighter. The specification demanded the aircraft be capable of performing three principal roles: fighter direction, in which it was required to lead formations of single-engine fighters ...

Sartrouville
Sartrouville () is a commune in the Yvelines department, Île-de-France, north central France. it is located in the north-western suburbs of Paris, from the center of Paris. Name In the Middle Ages the name Sartrouville was recorded in Medieval Latin as ''Sartoris Villa''. The origin and meaning of ''Sartoris Villa'' is still debated. Some think the name comes from the Roman patronym ''Saturus'' (probably a Gallo-Roman landowner) and means "estate (''villa'') of Saturus". Others believe that the word ''sartoris'' comes from the Medieval Latin past participle ''exsartum'' ("cleared for cultivation"), from Latin ''sartum'' ("hoed"), and means "estate of the land-clearers", probably in reference to the deforestation that took place around Sartrouville in Antiquity or in the Early Middle Ages to enable the cultivation of the land. Demographics Immigration Sport Most popular sports can be practiced in Sartrouville, but it is worldwide famous for its triathlon club called ECS Tr ...

Conventional Landing Gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 133. Aviation Supplies & Academics, 1997. From the Ground Up, 27th edition, page 11 The term taildragger is also used, although some argue it should apply only to those aircraft with a tailskid rather than a wheel. The term "conventional" persists for historical reasons, but all modern jet aircraft and most modern propeller aircraft use tricycle gear. History In early aircraft, a tailskid made of metal or wood was used to support the tail on the ground. In most modern aircraft with conventional landing gear, a small articulated wheel assembly is attached to the rearmost part of the airframe in place of the skid. This wheel may be steered by the pilot through a connection to the rudder pedals, allowing the rudd ... [...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 14M
The Gnome-Rhône 14M was a small 14-cylinder two-row air-cooled radial engine that was used on several French and German aircraft of World War II. While having the same appearance, number of pistons (14) and two-row layout typical of Gnome-Rhône radial engines, the 14M was built to a smaller frame intended to power a lighter class of aircraft. It was designed with lower displacement and power, smaller in size and with less weight compared to the larger, heavier Gnome-Rhône 14N and its well-known predecessor.
