Supermarine Type 224
The Supermarine Type 224 was an inverted gull-wing monoplane fighter aircraft designed by R.J. Mitchell at Supermarine in response to Air Ministry Specification F.7/30, which sought a fighter for introduction to succeed the Gloster Gauntlet. It was powered by the Rolls-Royce Goshawk engine, which used an experimental evaporative cooling system, and problems with this system, combined with its disappointing performance, led to it being rejected, a contract for production aircraft eventually going to the Gloster Gladiator. It is nevertheless notable because R.J. Mitchell learnt lessons from its failure that were to contribute greatly to his success with the Supermarine Spitfire. Design and development Specification F.7/30, which was formally issued to the aircraft industry in October 1931, called for an all-metal day and night fighter armed with four machine guns, a high top speed and rate of climb, and a landing speed of less than 60 mph. The importance of a good view fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine
Supermarine was a British aircraft manufacturer that is most famous for producing the Supermarine Spitfire, Spitfire fighter plane during World War II as well as a range of seaplanes and flying boats, and a series of Jet engine, jet-powered fighter aircraft after World War II. The company had successes in the Schneider Trophy for seaplanes, with three wins in a row of 1927, 1929 and 1931. The company was founded in 1913 as Pemberton-Billing Ltd on the River Itchen, Hampshire, River Itchen close to Woolston, Southampton, on ground previously purchased by Noel Pemberton Billing to construct motor launches. It produced a couple of prototypes using quadruplane designs to shoot down zeppelins, the Supermarine P.B.29 and the Supermarine Nighthawk. The aircraft were fitted with the recoilless rifle, recoilless Davis gun and the Nighthawk had a separate powerplant to power a searchlight.The World's Worst Aircraft James Gilbert Upon election as a Member of Parliament (United Kingdom), M ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1930s British Fighter 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.

Dewoitine D
Constructions Aéronautiques Émile Dewoitine was a French aircraft manufacturer established by Émile Dewoitine at Toulouse in October 1920. The company's initial products were a range of metal parasol-wing fighters which were largely ignored by the French Air Force but purchased in large quantities abroad and licence-built in Italy, Switzerland, and Czechoslovakia. The company was liquidated in January 1927, with the only remaining active programme (the D.27) being transferred to EKW in Switzerland. The company was re-established in Paris in March the following year as Société Aéronautique Française (Avions Dewoitine) or SAF. After briefly continuing D.27 production, the reconstituted firm produced a range of fighters that became a mainstay of the French airforce during the 1930s, the D.500 family. It also developed important civilian airliners, such as the D.333 and its derivative the D.338, designed for pioneering routes to French Indochina (Vietnam), and eventually Hon ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburn F3
The Blackburn F3 (also called the Blackburn F.7/30) was a British single-engined fighter aircraft produced in response to Air Ministry Specification F.7/30. Design and development Following the release of Air Ministry Specification F.7/30 for a single-seat day and night fighter, eight companies proposed twelve designs and three, including Blackburn Aircraft, received contracts to produce a prototype. Blackburn's design, the F.3, was a single-bay biplane of unequal wingspan and with an unusual configuration, the upper wing being mounted approximately halfway up the stressed-skin fuselage and the lower wing about two feet below it, the gap being occupied by an enclosure for the condenser of the evaporatively-cooled Goshawk III engine. The undercarriage was attached to the front spar of the lower wing, with diagonal struts transmitting the landing loads to the fuselage longerons. The wheels were fitted with spats but these were later removed. Four Vickers machine-guns were fusela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arado Ar 80
The Arado Ar 80 was a pre-World War II fighter aircraft, designed by Arado Flugzeugwerke to compete for the ''Luftwaffe''s first major fighter contract. The Ar 80 was uninspiring in terms of performance and also suffered a number of failures. The contest was eventually won by the Messerschmitt Bf 109, and the Ar 80 prototypes ended their days as test aircraft. Design and development With the Nazi rise to power in February 1933, a plan was put into place to dramatically expand the ''Luftwaffe''. The new and highly-political '' Reichsluftfahrtministerium'' (RLM) demanded that the large industrial firms cooperate, keeping construction as secret as possible. Arado Flugzeugwerke, under the direction of Erich Serno and Felix Wagenführ, largely stopped being a designer of aircraft and increasingly became a production facility for other companies. However, the company had just completed the Ar 65 biplane fighter. Several orders were placed for the Ar 65, and a follow-on Ar 68 model. ...
