Vickers Type 207
The Vickers Type 207 was a single-engined two-seat biplane designed as a shipborne torpedo bomber to an early 1930s specification. Structurally innovative, only one was built. Development The Vickers Type 207 was often known as the Vickers M.1/30, for it was built to Air Ministry specification for a carrier-based torpedo bomber to replace the Blackburn Ripon. The Air Ministry paid Vickers for a single prototype; its competitors were the Blackburn M.1/30 and the Handley Page H.P.46. Like Blackburn, Vickers chose the 825 hp (615 kW) Rolls-Royce H10 engine, later called the Buzzard IIIMS, a liquid cooled V-12 to power their aircraft. The Type 207 was a single-bay biplane, without sweep or stagger and with wings of almost equal span. The upper wing carried Handley Page slots and Frise ailerons; the lower wing alone had dihedral. Both wings used the relatively thick and still novel Raf34 airfoil section; they folded for storage. The rudder was balanced and the b ...

Ailerons
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement around the aircraft's longitudinal axis), which normally results in a change in flight path due to the tilting of the lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the First World War compelled the U.S. Government to legislate a legal resolution. A much earlier aileron concept was patented in 1868 by British scientist Matthew Piers Watt Boult ...

Vickers Aircraft
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems.

1930s British Military 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.

Vickers Machine Gun
The Vickers machine gun or Vickers gun is a water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every British soldier who ever fired one. It ...

V-12 Engine
A V12 engine is a twelve- cylinder piston engine where two banks of six cylinders are arranged in a V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in racing boats. Due to the balanced nature of the engine and the smooth delivery of power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, following which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary an ...

Mutt Summers
Captain Joseph "Mutt" Summers, (10 March 1904 – 16 March 1954) was chief test pilot at Vickers-Armstrongs and Supermarine. During his career, Summers flew many first flights on prototype aircraft, (a record of 54 by a test pilot), from the Supermarine Spitfire, to the Vickers Valiant. He also holds the current second place record for 366 general types tested, below Eric "Winkle" Brown's 487. Career Captain Joseph "Mutt" Summers received his nickname "Mutt" during his early days in the RAF from his habit of urinating before takeoff on the small rear wheel or skid of the aircraft he was testing. This led to his being accused of christening his aircraft like a dog marking its territory. He did this because he was aware that during some crashes a full bladder could prove fatal. Paul Brickhill (in ''The Dam Busters'') referred to the two test pilots Joseph Summers and Jeffrey Quill, as "Mutt" and "Jeff", alluding to the characters in the pioneering American comic strip created by ...

Leading Edge Slot
A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface. In this manner they allow flight at higher angles of attack and thus reduce the stall speed. Purpose and development At an angle of attack above about 15° many airfoils enter the stall. Modification of such an airfoil with a fixed leading-edge slot can increase the stalling angle to between 22° and 25°.Clancy, L.J., ''Aerodynamics'', Section 6.9 Slots were first developed by Handley Page in 1919 and the first aircraft to fly with them was the experimental H.P.17, a modified Airco DH.9A. Their invention is credited jointly to Sir Frederick Handley Page and Gustav Lachmann. The first aircraft fitted with controllable slots was the Handley Page H.P.20. Licensing the design became one of Handley Page's major s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
