Gloster II
The Gloster II was a British racing floatplane of the 1920s. A single-engined biplane, two were built to compete in the 1924 Schneider Trophy air race. However the crash of the first prototype during testing meant that it could not be made ready for the race, which was postponed. The second aircraft was also lost in a crash. Design and development The 1923 Schneider Trophy race for seaplanes had been won by the United States Navy with the Curtiss CR-3, a floatplane which outclassed Britain's entry, the Supermarine Sea Lion III flying boat.Mondey 1981, p. 40. In a change from previous years, where Britain's entries had been privately funded, the British Air Ministry ordered two racing seaplanes from the Gloster Aircraft Company to compete for the 1924 race.James 1971, p. 107. The resulting aircraft, designated the Gloster II, was a floatplane development of Gloster's earlier Gloster I racing aircraft, which had won the annual Aerial Derby air race three years runn ...

Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into multiple classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibians; then within these classes, there are records for aircraft in a number of weight categories. There are still further subdivisions for piston-engined, turbojet, turboprop, and rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline indicates unofficial records, including unconfirmed or unpublicized war secrets. Official records versus unofficial The Lockheed SR-71 Blackbird holds the official Air Speed Record for a manned airbreathing jet engine aircraft with a speed of . The reco ...

Floatplanes
A floatplane is a type of seaplane with one or more slender floats mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy. Either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. British usage is to call "floatplanes" "seaplanes" rather than use the term "seaplane" to refer to both floatplanes and flying boats. Use Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft, military seaplanes have stopped being used. This, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. However, numerous modern civilian aircraft have floatplane variants, most of these are offered as third-party modifications under a supplemental type certificate (STC), although there are several aircraft manufacturers that build floatplanes from scratch. These floatplanes have found thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Enthusiast
''Air Enthusiast'' was a British, bi-monthly, aviation magazine, published by the Key Publishing group. Initially begun in 1974 as ''Air Enthusiast Quarterly'', the magazine was conceived as a historical adjunct to '' Air International'' magazine. ''Air International'' was (and still is) involved with current aviation topics and the ''Quarterly'' concerned itself with historical matters. Each issue contained 80 pages; as a result certain articles were divided and each part appeared over a number of issues. ''Air Enthusiast'' was illustrated with colour and black-and-white photos, diagrams, profiles and three-view drawings. Earlier issues featured cutaway drawings, but these were dropped. The articles provided detail for varieties of aircraft An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from ...

Gloster IV
The Gloster IV was a British racing floatplane of the 1920s. A single-engined biplane, the Gloster IV was a development of the earlier Gloster III intended to compete in the 1927 Schneider Trophy race. One aircraft competed in the race, but retired part way through. The three aircraft built continued to be used as trainers by the High Speed Flight for several years. Design and development To compete for the 1927 Schneider Trophy, Britain's Air Ministry was determined to improve Britain's performance for the last few competitions, with British entries being soundly beaten by American Curtiss floatplanes in 1923 and 1925, and failing to even enter the 1926 competition which was won by the Italian Macchi M.39. To improve on this disappointing state of affairs, the Air Ministry placed orders for designs of high speed floatplanes from Gloster, Supermarine (the S.5) and Shorts (the Crusader).Mondey 1981, p.43.

Napier Lion VA
The Napier Lion is a 12-cylinder, petrol-fueled 'broad arrow' W12 configuration aircraft engine built by D. Napier & Son from 1917 until the 1930s. A number of advanced features made it the most powerful engine of its day and kept it in production long after other contemporary designs had been superseded. It is particularly well known for its use in a number of racing designs, for aircraft, boats and cars. Design and development Early in the First World War, Napier were contracted to build aero engines to designs from other companies, initially a Royal Aircraft Factory model and then Sunbeams. Both engines proved to be unreliable and in 1916 Napier decided to design an engine with high power, light weight and low frontal area. Napier's engineers laid out the engine with its 12 cylinders in what they called a "broad arrow"—three banks of four cylinders sharing a common crankcase. This suggested the design's first name, the Triple-Four. The configuration is also known as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeroelasticity
Aeroelasticity is the branch of physics and engineering studying the interactions between the inertial, elastic, and aerodynamic forces occurring while an elastic body is exposed to a fluid flow. The study of aeroelasticity may be broadly classified into two fields: ''static aeroelasticity'' dealing with the static or steady state response of an elastic body to a fluid flow; and ''dynamic aeroelasticity'' dealing with the body's dynamic (typically vibrational) response. Aircraft are prone to aeroelastic effects because they need to be lightweight and withstand large aerodynamic loads. Aircraft are designed to avoid the following aeroelastic problems: # divergence where the aerodynamic forces increase the angle of attack of a wing which further increases the force; # control reversal where control activation produces an opposite aerodynamic moment that reduces, or in extreme cases, reverses the control effectiveness; and # flutter which is the uncontained vibration that can lead ...

Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...

RAF Cranwell
Royal Air Force Cranwell or more simply RAF Cranwell is a Royal Air Force station in Lincolnshire, England, close to the village of Cranwell, near Sleaford. Among other functions, it is home to the Royal Air Force College (RAFC), which trains the RAF's new officers and Aircrew. The motto, ''Altium Altrix'', meaning "Nurture the highest" appears above the main doors of the Officers Mess. RAF Cranwell is currently commanded by Group Captain Joanne Campbell. History The history of military aviation at Cranwell goes back to November 1915,Halpenny (1981), p.74 when the Admiralty requisitioned 2,500 acres (10 km2) of land from the Marquess of Bristol's estate. On 1 April 1916, the "Royal Naval Air Service Training Establishment, Cranwell" was officially born. In 1917 a dedicated railway station was established for the RNAS establishment on a new single track branch line from Sleaford, the train being known as The Cranwell Flyer.A J Ludlam, ''The RAF Cranwell Railway'' ...

Gloster III
The Gloster III was a British racing floatplane of the 1920s intended to compete for the Schneider Trophy air race. A single-engined, single-seat biplane, two were built, with one finishing second in the 1925 race. Design and development In 1924, the Gloster Aircraft Company designed and built the Gloster II, a development of the Gloster I racing aircraft to compete in that year's Schneider Trophy air race. The first aircraft was written off during trials, however, and as there were no other competitors, the American Aero Club postponed the competition to 1925.James 1971, pp.107-109. In order to compete in the 1925 race, the British Air Ministry placed an order with Gloster for the design and build of two examples of a new racing seaplane in February 1925. The resulting design, the Gloster III, like the Gloster II, was a wooden biplane with single bay wings, powered by a 700 hp (522 kW) Napier Lion VII engine. The aircraft was fitted with Lamblin radiators on the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
