Supermarine Type 224
The Supermarine Type 224 was a British gull-wing monoplane fighter aircraft designed by R.J. Mitchell at Supermarine in response to Air Ministry Specification F.7/30, which sought to introduce a new fighter to succeed the Gloster Gauntlet. The Type 224 was powered by a Rolls-Royce Goshawk engine, which used an experimental evaporative cooling system. Problems with the cooling system, combined with its disappointing performance during trials, led to the Type 224 being rejected by the Air Ministry, a contract for production aircraft eventually going to the Gloster Gladiator. The type is nevertheless notable because Mitchell learnt lessons from its design that were to contribute to his success with the Supermarine Spitfire. Design and development Air Ministry Specification F.7/30 Air Ministry Specification F.7/30, which developed from O.R.1, was formally issued to the British aircraft industry in October 1931, called for an all-metal day and night fighter aircraft armed with ...

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-b ...

Hawker Aircraft
Hawker Aircraft Limited was a British aircraft manufacturer that was responsible for some of the most famous products in British aviation history. History Hawker had its roots in the aftermath of the First World War, which resulted in the bankruptcy of the Sopwith Aviation Company. Sopwith test pilot Harry Hawker and three others, including Thomas Sopwith, bought the assets of Sopwith and formed H. G. Hawker Engineering in 1920. In 1933, the company was renamed Hawker Aircraft Limited, and it took advantage of the Great Depression and a strong financial position to purchase the Gloster Aircraft Company in 1934. The next year, it merged with the engine and automotive company Armstrong Siddeley and its subsidiary, Armstrong Whitworth Aircraft, to form Hawker Siddeley Aircraft. This group also encompassed A. V. Roe and Company (Avro). The company continued to produce designs under the "Hawker" name as part of Hawker Siddeley Aircraft, which from 1955 was a division of Hawk ...

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 whi ...

Aircraft Fairing
An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.Crane, Dale: ''Dictionary of Aeronautical Terms, Third Edition'', page 206. Aviation Supplies & Academics Inc, Newcastle Washington, 1997. These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.Bingelis, Tony: ''The Sportplane Builder'', pages 261-265. Experimental Aircraft Association Aviation Foundation, 1979. Types On aircraft, fairings are commonly found on: ; Belly fairing : Also called a "ventral fairing", it is located on the underside of the fuselage between the main wings. It can also cover additional cargo storage or fuel tanks. ; Cockpit fairing : Also called a "cockpit pod", it protects the crew on ultralight trikes. Commonly made from fiberglass, it may also incorporate a windshield.Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page C-17. Cybai ...

Aerodynamic Drag
In fluid dynamics, drag, sometimes referred to as fluid resistance, is a force acting opposite to the direction of motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers, two solid surfaces, or between a fluid and a solid surface. Drag forces tend to decrease fluid velocity relative to the solid object in the fluid's path. Unlike other resistive forces, drag force depends on velocity. Drag force is proportional to the relative velocity for low-speed flow and is proportional to the velocity squared for high-speed flow. This distinction between low and high-speed flow is measured by the Reynolds number. Drag is instantaneously related to vorticity dynamics through the Josephson-Anderson relation. Examples Examples of drag include: * Net force, Net Aerodynamic force, aerodynamic or Fluid dynamics, hydrodynamic force: Drag acting opposite to the direction of movement of a solid object such as cars, aircraft, and boat hulls. * Viscou ...

Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for taxiing, takeoff or landing. For aircraft, it is generally needed for all three of these. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or Seaplane, floats needed to operate from snow/ice/water and skids for vertical operation on land. Retractable undercarriages fold away during flight, which reduces drag (physics), drag, allowing for faster airspeeds. Landing gear must be strong enough to support the aircraft and its design affects the weight, balance and performance. It often comprises three wheels, or wheel-sets, giving a tripod effect. Some unusual land ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 wings. 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 slowe ...

Schneider Trophy
The Coupe d'Aviation Maritime Jacques Schneider, also known as the Schneider Trophy, Schneider Prize or (incorrectly) the Schneider Cup is a trophy that was awarded first annually, and later biennially, to the winner of a race for seaplanes and flying boats. In 1931 Britain met the conditions to retain the Trophy permanently; it is on display at the Science Museum in South Kensington, London. Announced in 1912 by Jacques Schneider, a French financier, balloonist and aircraft enthusiast, the competition offered a prize of approximately £1,000. The race was held twelve times between 1913 and 1931, the year when it was finally won permanently by the British. It was intended to encourage technical advances in civil aviation but became a contest for pure speed with laps over a (usually) triangular course, initially and later extended to . The contests were staged as time trials, with aircraft setting off individually at set intervals, usually 15 minutes apart. The contests were v ...

Bristol Type 133
The Bristol Type 133 was a single-seat, single-engine monoplane fighter armed with four guns, using stressed-skin construction and with a retractable undercarriage. It was built by The Bristol Aeroplane Co. to meet Specification F.7/30. The single example crashed before the trials commenced. Development Specification F.7/30 called for a four-gun fighter with better high-altitude performance and endurance than current fighters, outstanding climb rate, manoeuvrability and all-round vision combined with a low landing speed. A preference was expressed for the use of the experimental evaporatively-cooled Rolls-Royce Goshawk engine. None of Bristol's three design submissions were chosen for official prototype orders, but one, the Goshawk-engined Bristol Type 123 was built as a private venture contender. At the same time Bristol started work on a second design. Powered by a Bristol Mercury radial engine, the Type 133 was a low-wing cantilever monoplane and was the first aircraft ...

Bristol Type 123
The Bristol Type 123 was a single-seat, single-engine biplane fighter built to a United Kingdom Air Ministry specification for a four-gun fighter in the early 1930s. Only one was built. Development In late 1931 the Air Ministry released Air Ministry specification F.7/30. This was for a four-gun fighter with better high-altitude performance and endurance than current fighters, outstanding climb rate, manoeuvrability and all-round vision combined with a low landing speed. It was made clear that the evaporatively-cooled Rolls-Royce Goshawk was the preferred engine. The best-known outcome of this specification was the crank-winged Supermarine Type 224 monoplane with an open cockpit and fixed undercarriage designed by R.J. Mitchell. Bristol submitted several biplane designs, none of which brought an order for a prototype, but they were invited to offer a private-venture aircraft. The Bristol Type 123 was the result. Bristol's last biplane, it was of compact, striking appearance a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
