Blackburn F.3
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] |

Armstrong Whitworth Scimitar
The Armstrong Whitworth A.W.35 Scimitar was a British single-engine biplane fighter aircraft designed and built by Armstrong Whitworth Aircraft. Four Scimitars were produced for the Norwegian Army Air Service and were delivered in 1936. Design and development The A.W.35 Scimitar was a development of Armstrong Whitworth's earlier Armstrong Whitworth A.W.16 fighter, powered by an Armstrong Siddeley Panther engine, with a lowered nose decking and an enlarged fin and rudder. The first prototype ''(G-ACCD)'' was a modification of the second A.W.16, and first flew in this form on 29 April 1935. A second prototype (''G-ADBL'') was constructed by converting another A.W.16. Operational history Four Scimitars were ordered for the Norwegian Army Air Service, and an agreement signed for licence production at the Norwegian Army Aircraft Factory at Kjeller. After testing by the A & AEE at Martlesham Heath in late 1935, the four Scimitars were delivered to Norway in 1936. The licence agreem ...

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.

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.

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] |
Rolls-Royce Goshawk
The Rolls-Royce Goshawk was a development of the Rolls-Royce Kestrel that used evaporative or steam cooling. In line with Rolls-Royce convention of naming piston engines after birds of prey, it was named after the goshawk. The engine first ran in 1933 and provided 660 horsepower (490 kW). Only a few engines were built as the aircraft designs intended to use it were not adopted by the Royal Air Force. The Goshawk was used to power the Short Knuckleduster, the Supermarine Type 224 (a predecessor to the Supermarine Spitfire) and other prototype aircraft. Design and development The Goshawk was developed from the Kestrel IV prototype engine, to use evaporative (also known as "steam") cooling. Rather than keep the cooling liquid below its boiling point in the cooling system, the coolant was allowed to boil; the phase change from liquid to vapour takes more heat from the engine, so less weight of coolant is needed. However, the radiator had to be bulkier to accommodate coola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
