Martinsyde Buzzard
The Martinsyde F.4 Buzzard was developed as a powerful and fast biplane fighter for the Royal Air Force (RAF), but the end of the First World War led to the abandonment of large-scale production. Fewer than 400 were eventually produced, with many exported. Of particular note was the Buzzard's high speed, being one of the fastest aircraft developed during World War I. Design and development In 1917, George Handasyde of Martinsyde designed a single-seat biplane fighter powered by a Rolls-Royce Falcon V-12 engine, the Martinsyde F.3, with a single prototype being built as a private venture without an official order, and had flown at Brooklands aerodrome by October 1917.Bruce ''Air International'' July 1977, p. 28. six being ordered in 1917, with the first flying in November that year.

Fighter Aircraft
Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets. 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 and some types, such as fighter-bombers, are designed from the outset for dual roles. Other fighter designs are highly specialized while still filling the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armistice With Germany (Compiègne)
The Armistice of 11 November 1918 was the armistice signed at Le Francport near Compiègne that ended fighting on land, sea, and air in World War I between the Entente and their last remaining opponent, Germany. Previous armistices had been agreed with Bulgaria, the Ottoman Empire and Austria-Hungary. It was concluded after the German government sent a message to American president Woodrow Wilson to negotiate terms on the basis of a recent speech of his and the earlier declared " Fourteen Points", which later became the basis of the German surrender at the Paris Peace Conference, which took place the following year. Also known as the Armistice of Compiègne (french: Armistice de Compiègne, german: Waffenstillstand von Compiègne) from the place where it was officially signed at 5:45 a.m. by the Allied Supreme Commander, French Marshal Ferdinand Foch, it came into force at 11:00 a.m. Central European Time (CET) on 11 November 1918 and marked a vi ...

Rolls-Royce Falcon III
The Rolls-Royce Falcon is an aero engine developed in 1915. It was a smaller version of the Rolls-Royce Eagle, a liquid-cooled V-12 of 867 cu in (14.2 L) capacity. Fitted to many British World War I-era aircraft, production ceased in 1927. The Falcon was designed by R.W. Harvey-Bailey. An airworthy Falcon survives today and powers a Bristol F.2 Fighter during summer displays. Design and development Production of the Falcon began in September 1916 and was so successful that it was also manufactured under licence by Brazil Straker in Bristol. Production continued until 1927, by which time 2,185 had been built.Lumsden 2003, p.188. An unusual feature of this engine was the epicyclic propeller reduction gear which contained a clutch designed to limit the maximum torque, thus protecting the reduction gears.Guttery 1969, p.27. The Falcon was notably used in the Bristol F.2 Fighter and Blackburn Kangaroo bomber. Variants ''Note:'' ;Falcon I (''Rolls-Royce 190 hp Mk I'') :(1916 ...

Amherst Villiers
Amherst Villiers (1900–1991) was an English automotive, aeronautical and astronautic engineer and portrait painter. He designed a land speed record-breaking car for Malcolm Campbell, and developed the supercharged "Blower Bentley", driven by Henry Birkin and (in fiction) by James Bond. Early life Charles Amherst Villiers was born in London on 9 December 1900, the son of Ernest Amherst Villiers and the Hon. Elaine Augusta Guest. He was educated at Oundle School and at Gonville and Caius College, Cambridge. Career Villiers began his automotive career modifying Brescia Bugattis and supercharging a Vauxhall for racing driver Raymond Mays. He designed the Napier-Campbell Blue Bird which Malcolm Campbell used to break the land speed record in 1927 with an average speed of 174.88 mph. The 'Blower Bentley' was developed in ' Bentley Boy' Henry 'Tim' Birkin's workshop in 1929, using an Amherst Villiers supercharger bolted to the front of a Bentley 4½ Litre, to boost its ...

ADC Nimbus
The ADC Nimbus was a British inline aero engine that first ran in 1926. The Nimbus was developed from the Siddeley Puma aero engine by Frank Halford of the Aircraft Disposal Company, the goal was to develop the Puma to produce its intended power output which Halford eventually achieved. The Nimbus was further developed into an air-cooled version known as the ADC Airsix which did not enter production and was not flown.Lumsden 2003, p. 55.

Armstrong Siddeley Jaguar
The Armstrong Siddeley Jaguar was an aircraft engine developed by Armstrong Siddeley. The Jaguar was a petrol-fuelled air-cooled 14-cylinder two-row radial engine design. The Jaguar III was first used in 1923, followed in 1925 by the Jaguar IV and in 1927 by the Jaguar VI. In 1925 the Jaguar became the first production aero engine incorporating a geared supercharger. Design and development The Jaguar was developed from the Royal Aircraft Factory RAF.8 design proposal of 1917, and was engineered to use a gear-driven supercharger. First run on 21 June 1922 initial performance was not as expected; as a result the stroke was increased to 5.5 in (139.7 mm) on all variants after the Jaguar I. Throughout its career the Jaguar suffered from vibration due to a lack of a crankshaft centre bearing. The most powerful version of the engine, the Jaguar VIC, produced a maximum of 490 hp (365 kW) on takeoff at 1,950 rpm and weighed 910 lb (413 kg). The later Lyn ...

Martinsyde F6 ExCC
Martinsyde was a British aircraft and motorcycle manufacturer between 1908 and 1922, when it was forced into liquidation by a factory fire. History The company was first formed in 1908 as a partnership between H.P. Martin and George Handasyde and known as Martin & Handasyde. Their No.1 monoplane was built in 1908–1909 and succeeded in lifting off the ground before being wrecked in a gale. They went on to build a succession of largely monoplane designs although it was a biplane, the S.1 of 1914, that turned Martin-Handasyde into a successful aircraft manufacturer. In 1915 they renamed the company Martinsyde Ltd, and it became Britain's third largest aircraft manufacturer during World War One, with flight sheds at Brooklands and a large factory in nearby Woking. Martinsyde Motorcycles Martinsyde began manufacturing motorcycles from 1919 after buying the rights to engine designs by Howard Newman, which included a 350 cc single and a 677 cc V-twin with an unusual exh ...

Independent Air Force
The Independent Air Force (IAF), also known as the Independent Force or the Independent Bombing Force and later known as the Inter-Allied Independent Air Force, was a First World War strategic bombing force which was part of Britain's Royal Air Force and was used to strike against German railways, aerodromes, and industrial centres without co-ordination with the Army or Navy. Establishment From late 1916 to early 1917 the Royal Naval Air Service (RNAS) had attempted a co-ordinated series of bombing raids on German-held targets. Whilst the attacks were generally unsuccessful the principle of deep penetration bombing raids against strategic targets was established. General Jan Smuts, a member of the War Cabinet, prepared the Smuts Report which recommended that a separate Air Ministry and Air Force should be set up, independent of the Army and Navy and that a strategic bomber force should be formed whose sole purpose was to attack Germany. Following the perceived success in bombi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic, and consisted of various socialist, communist, separatist, anarchist, and republican parties, some of which had opposed the government in the pre-war period. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Flying School
The Central Flying School (CFS) is the Royal Air Force's primary institution for the training of military flying instructors. Established in 1912 at the Upavon Aerodrome, it is the longest existing flying training school. The school was based at RAF Little Rissington from 1946 to 1976. Its motto is ''Imprimis Praecepta'', Latin for "The Teaching is Everlasting". The school currently manages a series of training squadrons and the RAF Display Team.
