Wibault 280
The Wibault 280-T was a French 12-passenger civil airliner produced by Wibault backed by money from the Penhoët shipyards and also known as 'Penhoët Wibault'. Design and development The prototype Penhoët Wibault 280-T first flew at Villacoublay in November 1930 with the development backed by funds from the Penhoët shipyards of St Nazaire. It was an all-metal low-wing cantilever monoplane powered by three 300 hp (224 kW) Hispano-Wright 9Qa radial engines although these were soon replaced by three Gnome-Rhône 7Kb and the aircraft was redesignated the Wibault 281-T. A second aircraft was built to the 281 standard but then it was converted to a Wibault 282-T with three 350 hp (261 kW) Gnome-Rhône 7Kd engines and room for 12 passengers, seven further aircraft were built as 282s. Some of the 282s were operated by Air Union on the Paris-London ''Voile d'Or'' ("Golden Clipper") service in 1933. In 1934 Air France took delivery of the first of ten Wibault 283- ...

Cricket Pitch
In the game of cricket, the cricket pitch consists of the central strip of the cricket field between the wickets. It is long (1 chain) and wide. The surface is flat and is normally covered with extremely short grass, but can be completely dry or dusty soil with barely any grass or, in some circumstances (that are rarely seen in high level cricket), made from an artificial material. Over the course of a cricket match, the pitch is not repaired or altered other than in special circumstances - meaning that it will change condition. Any grass on the pitch in the game's first over, for example, may have disappeared by twentieth over due to wear. As almost all deliveries bowled will bounce off the pitch towards the batter, the state and type of a cricket pitch can significantly affect the outcome of a match. For example, a dusty, very dry, pitch will favour spin bowling because the ball will grip more on a dusty pitch - giving the team with the superior spin bowlers a significan ...

Low-wing Aircraft
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 ...

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 ...

Wibault 282 T12 3-view L'Aerophile September 1933
The Wibault company or ''Société des Avions Michel Wibault'' was a French aircraft manufacturing company. Its workshops were located in Billancourt, in the Paris area. History The Wibault company was established in 1919 by Michel Wibault. The planes produced by Wibault in the first decade included reconnaissance, fighter and bomber aircraft, but production shifted mainly to civilian aircraft after 1930. Some of the Wibault designs were quite successful; the Vickers Wibault was a licensed version of the Wibault 7 built by the British company Vickers in the 1920s. In 1930 Société des Avions Michel Wibault built the Wibault-Penhoët 280, which was funded by the Penhoët (Chantiers St. Nazairre) shipyard and the following year the companies merged to form Chantiers Aéronautiques Wibault-Penhoët. That company produced the Wibault-Penhoët 280 series of trimotor airliners, twelve of which were bought by Air France. They also built transport and racing types but in 1934 were ...

French Air Force
The French Air and Space Force (AAE) (french: Armée de l'air et de l'espace, ) is the air and space force of the French Armed Forces. It was the first military aviation force in history, formed in 1909 as the , a service arm of the French Army; it became an independent military branch in 1934 as the French Air Force. On 10 September 2020, it assumed its current name, the French Air and Space Force, to reflect an "evolution of its mission" into the area of outer space. The number of aircraft in service with the French Air and Space Force varies depending on the source; the Ministry of Armed Forces gives a figure of 658 aircraft in 2014. According to 2018 data, this figure includes 210 combat aircraft: 115 Dassault Mirage 2000 and 95 Dassault Rafale. As of 2021, the French Air and Space Force employs a total of 40,500 regular personnel, with a reserve element of 5,187 in 2014. The Chief of Staff of the French Air and Space Force (CEMAAE) is a direct subordinate of the Chief of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NACA Cowling
The NACA cowling is a type of aerodynamic fairing used to streamline radial engines installed on airplanes. It was developed by Fred Weick of the National Advisory Committee for Aeronautics (NACA) in 1927. It was a major advance in aerodynamic drag reduction, and paid for its development and installation costs many times over due to the gains in fuel efficiency that it enabled. History and design The NACA cowling enhanced speed through drag reduction while delivering improved engine cooling. The cowling consists of a symmetric, circular airfoil that is wrapped around the engine. In a normal planar airfoil, like a wing, it is the difference in airspeed, and their associated changes in pressure, on the top and bottom of the surface that produces lift. In the case of the NACA cowl, the ring-shaped airfoil is positioned so this lift effect is forward, producing thrust. This thrust does not counteract the total drag of the cowl, but greatly reduces its overall value. The differenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hispano-Wright 9Qa
The Wright R-975 Whirlwind was a series of nine-cylinder air-cooled radial aircraft engines built by the Wright Aeronautical division of Curtiss-Wright. These engines had a displacement of about and power ratings of . They were the largest members of the Wright Whirlwind engine family to be produced commercially, and they were also the most numerous. During World War II, Continental Motors built the R-975 under license as a powerplant for Allied tanks and other armored vehicles. Tens of thousands of engines were built for this purpose, dwarfing the R-975's usage in aircraft, where it was overshadowed by the similar Pratt & Whitney R-985. After the war, Continental continued to produce its own versions of the R-975 into the 1950s. Some of these produced as much as . The R-975 powered the American World War II M18 Hellcat tank destroyer which was claimed to have been the fastest tracked armored vehicle until the introduction of the turbine powered M1 Abrams in the 1980s.

Rudder Of Wibault-Penhoët 283
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally air or water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydra ...
