De Havilland Doncaster
The de Havilland DH.29 Doncaster was a British long-range high-wing monoplane of the 1920s built by de Havilland. History The DH.29 Doncaster was ordered by the British Air Ministry as an experimental long-range monoplane. The aircraft was a high-wing cantilever monoplane with unswept wings of wooden structure with a fabric covering. It had a box section wooden fuselage with a single fin. The crew of two sat in an open cockpit ahead of the wing. Two aircraft were built between 1920 and 1921 at Stag Lane Aerodrome. Early testing of the first aircraft ( Serial ''J6849'') resulted in a redesign of the engine installation. The second aircraft (Registered G-EAYO) was built as a ten-seat commercial aircraft. The airlines were not interested and further development was abandoned, effort being put into the biplane de Havilland DH.34. A proposed military reconnaissance version, the DH.30, was never built. The two aircraft finished their life at RAF Martlesham Heath with tests and trials, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland
The de Havilland Aircraft Company Limited () was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware on the outskirts of north London. Operations were later moved to Hatfield in Hertfordshire. Known for its innovation, de Havilland was responsible for a number of important aircraft, including the Moth biplane which revolutionised aviation in the 1920s; the 1930s Fox Moth, a commercial light passenger aircraft; the wooden World War II Mosquito multirole aircraft; and the pioneering passenger jet airliner Comet. The de Havilland company became a member of the Hawker Siddeley group in 1960, but lost its separate identity in 1963. Later, Hawker Siddeley merged into what is eventually known today as BAE Systems, the British aerospace and defence business. The de Havilland name lives on in De Havilland Canada, which owns the rights to the name and the aircraft produced by de Havilland's former Canadian subsidiary, inc ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-wing Aircraft
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplane (aeronautics), 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 (aeronautics), bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, ...

1921 In Aviation
This is a list of aviation-related events from 1921: Events * Mexicana de Aviación begins service. * The Imperial Japanese Navy acquires its first rigid and semi-rigid airships. * The Italian General Giulio Douhet publishes his highly influential book ''Command of the Air''. In it, he argues that the ability of aircraft to fly over armies and navies renders those forces of secondary importance; that the vastness of the sky makes defense against bombers impossible; that only offensive bombing to destroy the enemys air force can allow a country to achieve command of the air; that once it is achieved, a bombing campaign can be carried out against enemy "vital centers", including industry, transportation, government, communications, and "the will of the people;" and that success against enemy civilian morale in particular would be the key to victory. * When the Italian Chief of the Naval Staff Admiral Paolo Thaon di Revel argues for the development of aircraft carriers, saying "t ...

List Of Aircraft Of The Royal Air Force
Many aircraft types have served in the British Royal Air Force since its formation in April 1918 from the merger of the Royal Flying Corps and Royal Naval Air Service. This is a list of RAF aircraft, including all currently active and retired types listed in alphabetic order by their RAF type name. For just those aircraft currently in service, see List of active United Kingdom military aircraft. Aircraft operated with the Fleet Air Arm from 1924 until 1939 were operated by the Royal Air Force on behalf of the Navy and are included; those operated by the Royal Navy after it re-acquired control of the aircraft used to support its operations in 1939 are not, but all aircraft operated in conjunction with the Navy are listed at List of aircraft of the Fleet Air Arm. Army Air Corps aircraft are not included but can be found at List of aircraft of the Army Air Corps.

Scarff Ring
The Scarff ring was a type of machine gun mounting developed during the First World War by Warrant Officer (Gunner) F. W. Scarff of the Admiralty Air Department for use on two-seater aircraft. The mount incorporated bungee cord suspension in elevation to compensate for the weight of the gun, and allowed an airgunner in an open cockpit to swivel and elevate his weapon (a Lewis machine gun) quickly, and easily fire in any direction. Later models permitted the fitting of two Lewis guns; while this doubled the firepower available, operation of the paired guns was more cumbersome, and required considerable strength from the gunner, especially at altitude, so that many gunners preferred the original single gun - and this became the postwar standard. In either case, the mounting was simple and rugged, and gave its operator an excellent field of fire. It was widely adapted and copied for other airforces. As well as becoming a standard fitting in the British forces during the First World W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napier Lion IB
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
