Rolls-Royce Falcon
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'') :(1 ...

Bristol F2B Fighter
The Bristol F.2 Fighter is a British First World War two-seat biplane fighter and reconnaissance aircraft developed by Frank Barnwell at the Bristol Aeroplane Company. It is often simply called the Bristol Fighter, ''"Brisfit"'' or ''"Biff"''. Although the type was intended initially as a replacement for the pre-war Royal Aircraft Factory B.E.2c reconnaissance aircraft, the new Rolls-Royce Falcon V12 engine gave it the performance of a fighter. Despite a disastrous start to its career, the definitive F.2B version proved to be a manoeuvrable aircraft that was able to hold its own against single-seat fighters while its robust design ensured that it remained in military service into the early 1930s. Some surplus aircraft were registered for civilian use, and versions with passenger cabins were converted. Development Origins In the Autumn of 1915, the Royal Flying Corps (RFC) needed a new aerial reconnaissance and artillery spotting aircraft to replace the pre-war Royal Aircraft ...

Epicyclic Gearing
An epicyclic gear train (also known as a planetary gearset) consists of two gears mounted so that the center of one gear revolves around the center of the other. A carrier connects the centers of the two gears and rotates the planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an ''annular gear''. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid. The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a ''planetary gear train''.J. J. Uicker, G. R. Pennock and J. E.

Curtiss H-12
The Curtiss Model H was a family of classes of early long-range flying boats, the first two of which were developed directly on commission in the United States in response to the £10,000 prize challenge issued in 1913 by the London newspaper, the ''Daily Mail'', for the first non-stop aerial crossing of the Atlantic. As the first aircraft having transatlantic range and cargo-carrying capacity, it became the grandfather development leading to early international commercial air travel, and by extension, to the modern world of commercial aviation. The last widely produced class, the Model H-12, was retrospectively designated Model 6 by Curtiss' company in the 1930s, and various classes have variants with suffixed letters indicating differences. Design and development Having transatlantic range and cargo carrying capacity by design, the first H-2 class (soon dubbed ''"The Americans"'' by the Royal Navy) was quickly drafted into wartime use as a patrol and rescue aircraft by the RNAS ...

Bristol Tourer
The Bristol Tourer was a British civil utility biplane produced in the years following the First World War, using as much as possible from the design of the Bristol Fighter aircraft. Bristol Tourers were delivered with a variety of engines, subject to availability and customer desires; these included the Rolls-Royce Falcon, Siddeley Puma, Hispano-Suiza 8, and Wolseley Viper. Many Tourers were fitted with a canopy to cover the one or two passenger seats in the rear cockpit, giving the type its original name of Coupé. The pilot's cockpit, however, remained open. Bristol Tourers operated by Western Australian Airways made the first scheduled airline services in Australia, commencing on 4 December 1921 between Perth and Geraldton. Variants ;Type 27 :First Tourers for the British Controller of Civil Aviation, fitted with Rolls-Royce Falcon engines and dual controls (3 built) ;Type 28 :Similar to Type 27 with canopy for rear seat ;Type 29 :Siddeley Puma-engined version for Bri ...

Blackburn Sprat
The Blackburn T.R.1 Sprat was a British single-engine two-seat biplane trainer, built in 1926 for advanced training, deck-landing and seaplane experience. Just one was built. Development The Sprat was designed to Air Ministry Specification 5/24 as an RAF advanced trainer and Fleet Air Arm deck-landing trainer. It was specified that the aircraft should be readily convertible to a seaplane, again to be used as a trainer. The specification produced contracts for three machines, the Vickers Vendace, the Parnall Perch and the Sprat. The Sprat, though a smaller aircraft, had strong family resemblances to the earlier Velos torpedo bomber. The Sprat was a staggered, single-bay biplane with equal-span wings that could be folded for carrier stowage. The fuselage centre section was built around a tubular-steel structure which linked the engine mounting and the wooded-framed rear fuselage. The two dual-control open cockpits were both behind the trailing edge of the wing for optimum v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro 529
The Avro 529 was a twin-engined biplane long-range bomber of the First World War. Two prototypes were built but no production ensued. Development The Avro 529 was Avro's second twin-engined aircraft and their second attempt at a heavy bomber. Their first in both categories was the Pike, developed in early 1916 to Royal Flying Corps (RFC) guidelines for a short-range bomber. The Pike arrived too late to secure orders from the RFC who would order the Handley-Page O/100 and for the Royal Naval Air Service (RNAS) who had ordered the Short Bomber. Nonetheless, after trials of the Pike, the Admiralty ordered two prototypes of an enlarged Pike for a long-range bomber role. This was the Type 529. Like the Pike, it was a large twin-engined biplane of the then-standard wood and canvas construction. It had three-bay wings without sweepback, dihedral or stagger, partly to facilitate wing folding. The vertical tail was different from that of the Pike: it had a small, roughly triangula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro Pike
The Avro 523 Pike (the first Avro aircraft to receive a name) was a British multi-role combat aircraft of the World War I, First World War that did not progress past the prototype stage. It was intended to provide the Royal Naval Air Service with an anti-Zeppelin fighter that was also capable of long-range reconnaissance and bomber, bombing. Design and development The Avro Pike was a large, three-bay biplane of conventional layout driven by two pusher propellers. Three open cockpits were provided, the centre one for the pilot, with gunners fore and aft of him. The British Admiralty, Admiralty evaluated the type, but rejected it. Avro then built a second prototype, substituting the original's Sunbeam engines for Green E.6 engines instead and designated it the 523A. Operational history The Admiralty evaluated this in November 1916, but found that the type was by then obsolete and did not place an order. The two prototypes flew as testbeds with Avro for the remainder of the war. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...
