De Havilland DH.71 Tiger Moth
The de Havilland DH.71 Tiger Moth was a British single-seat monoplane, designed to research high-speed flight and to test replacement engines for the Cirrus. Only two were built. Design and development It was a low-wing monoplane based on the earlier Moth biplanes with a stressed plywood covering and the cockpit designed around its test pilot, Hubert Broad, to make it as streamlined as possible: this resulted in the fuselage sides being sloped outwards to accommodate his shoulders. The Tiger Moth had a fixed conventional landing gear with a tail skid. The first aircraft built (registration ''G-EBQU'') first flew from Stag Lane Aerodrome on 24 June 1927 and was fitted with an ADC Cirrus II engine to check its handling characteristics. This was then replaced with Major Halford's prototype engine, by then named the Gipsy. The second example, ''G-EBRV'', was fitted with a Cirrus engine and first flew on 28 July 1927. Operational history Both aircraft were entered for the 1927 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

King's Cup Race
The King's Cup air race is a British handicapped cross-country event, which has taken place annually since 1922. It is run by the Royal Aero Club Records Racing and Rally Association. The King's Cup is one of the most prestigious prizes of the British air racing season. The entrants are divided into classes, and each is evaluated and given a time handicap for the start of the race. They all take off at varying times according to their handicap, with the handicappers' aim being that they should all cross the finishing line at the same moment. The art of winning the race outright is therefore to beat the handicappers, rather than to make the fastest flight as such.Alex Henshaw, ''The Flight of the Mew Gull'', Murray, 1980. p.95 The aircraft are also divided into classes, with a winner for each class as well as the outright winner. History The King's Cup air race was established by King George V as an incentive to the development of light aircraft and engine design. Initially, i ...

Low-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower ...

Racing Aircraft
Air racing is a type of motorsport that involves airplanes or other types of aircraft that compete over a fixed course, with the winner either returning the shortest time, the one to complete it with the most points, or to come closest to a previously estimated time. History The first 'heavier-than-air' air race was held on 23 May 1909 - the Prix de Lagatinerie, at the Port-Aviation airport south of Paris, France. Four pilots entered the race, two started, but nobody completed the full race distance; though this was not unexpected, as the rules specified that whoever travelled furthest would be the winner if no-one completed the race. Léon Delagrange, who covered slightly more than half of the ten laps was declared the winner. Some other minor events were held before the ''Grande Semaine d'Aviation de la Champagne'' in 22–29 August 1909 at Reims, France. This was the first major international flying event, drawing the most important aircraft makers and pilots of the era, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of De Havilland Aircraft
This is a list of aircraft produced or proposed by Geoffrey de Havilland or designed at the de Havilland Aircraft Company from its founding in 1920 until its purchase by (and integration into) the Hawker Siddeley Group in 1959. The aircraft are ordered by de Havilland model number; The numbers started with de Havilland's employment at Airco company as chief designer. Although Airco ''built'' the planes, their design was owned by de Havilland and when de Havilland started his own company, he continued the numbering. The numbering sequence continued for later designs of de Havilland's aircraft company, even if they were designed by a factory team with little input from de Havilland himself. The DH.89, for example, was the 89th de Havilland design. The designs DH.121 and DH.125 which were under development when de Havilland lost its separate identity under Hawker Siddeley kept their numbering and were produced as the Hawker Siddeley HS-121 Trident and the Hawker Siddeley HS.125. ...

Airstrike
An airstrike, air strike or air raid is an offensive operation carried out by aircraft. Air strikes are delivered from aircraft such as blimps, balloons, fighters, heavy bombers, ground attack aircraft, attack helicopters and drones. The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective as opposed to a larger, more general attack such as carpet bombing. Weapons used in an airstrike can range from direct-fire aircraft-mounted cannons and machine guns, rockets and air-to-surface missiles, to various types of aerial bombs, glide bombs, cruise missiles, ballistic missiles, and even directed-energy weapons such as laser weapons. In close air support, air strikes are usually controlled by trained observers on the ground for coordination with ground troops and intelligence in a manner derived from artillery tactics.

De Havilland Gipsy
The de Havilland Gipsy is a British air-cooled four-cylinder in-line aircraft engine designed by Frank Halford in 1927 to replace the ADC Cirrus in the de Havilland DH.60 Moth light biplane. Initially developed as an upright 5 litre (300 cubic inch) capacity engine, later versions were designed to run inverted with increased capacity and power. The Gipsy went on to become one of the most popular sport aircraft engines of the inter-war period and was the engine of choice for various other light aircraft, trainers, liaison aircraft and air taxis, British as well as foreign, until long past World War II. Apart from helping to establish the de Havilland Aircraft Company as a manufacturer of light aircraft, it also established the company as an engine manufacturer in its own right. Gipsy engines remain in service powering vintage light aircraft. Design and development Just like the ADC Cirrus, the Gipsy was born as a collaboration between aircraft manufacturer Geoffre ...
