Leitner-Watts
The Metal Airscrew Company was formed in 1919 by Dr. Henry Charles Watts and Henry Leitner to produce hollow metal aircraft propellers with a method set out their joint patent. By 1928 the company name had changed to Metal Propellers Ltd. It remained active until at least 1930. History The Leitner-Watts propellers were amongst the earliest with a thick metal aerodynamic profile. Watts was the aerodynamicist who determined the blade profile, Leitner the engineer who translated it into metal and designed hubs for two, three and four bladed propellers. The blades were produced in the Rubery Owen factory in Darlaston, Staffordshire. Each blade side or shell was made up from three laminations of steel sheet, shaped in a press. The outer layer formed the complete shell shape and the progressively shorter, Y-shaped inner laminations strengthened the bade towards the root. The laminations were riveted or spot-welded together and the two shells welded together at their edges. To sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handley Page Handcross
The Handley Page Handcross was a single-engined biplane day bomber built to an Air Ministry specification. It was not put into production and only the three prototypes were built. Development In August 1923 the Air Ministry issued List of Air Ministry specifications#1920–1929, specification 26/23, which called for a day bomber powered by a Rolls-Royce Condor#Specifications (Condor III), Rolls-Royce Condor III engine which could carry a 550 lb (250 kg) bomb load with a 500-mile (800 km) range. In response, Handley Page designed what was known at the time as the C/7 Handcross but retrospectively became the H.P.28 Handcross after the introduction of the familiar H.P. type numbers in about 1927. The Handcross was constructed from wood and fabric throughout. It was a three-bay biplane with equal-span wings without stagger or sweep. The wings had parallel chord but the lower planes were significantly narrower than the upper; only the lower planes carried dihedral. Ail ...

Westland Yeovil
The Westland Yeovil was a British biplane bomber designed and built by Westland Aircraft in 1923 to meet an Air Ministry Specification for a single-engined day bomber. Development The Yeovil was designed to meet Air Ministry Specification 26/23 for a single-engined day bomber, with a Rolls-Royce Condor engine specified by the ministry. It was a two-bay staggered biplane of composite wood and metal construction. It had a crew of two with the pilot in a cockpit at the front with the bomb aimer/gunner behind. It was powered by a nose-mounted tractor Rolls-Royce Condor IIIA piston engine, fitted with a Leitner-Watts metal propeller. Three prototypes were ordered, the first prototype ''J7508'' made its first flight in 1925 from RAF Andover, with Captain Frank Courtney as the test pilot. The prototype was delivered to RAF Martlesham Heath for evaluation against the other aircraft built to meet the specification, the Hawker Horsley and the Bristol Berkeley. After evaluation th ...

Bristol Seely
The Bristol Seely was entered into an Air Ministry competition for safe civil aeroplanes held in 1920. It was a single-engine biplane with accommodation for one passenger. After the competition, the single Seely was used as a testbed for the Bristol Jupiter engine development programme. Development The 1920 civil aeroplane competition emphasised safety in terms of a short takeoff and slow landing speed as well as useful load and economy. The rules of the competition were released in July 1919 and Bristol decided that a modification of the Tourer was their best hope. The single passenger was enclosed in a cabin immediately behind the pilot's open cockpit, with a raised roof and windows in the decking where the second seat in the Tourer had been. In addition, the fuselage was deepened by dropping the lower longerons and floor to the lower wing spar. Ahead of the pilot, the fuselage bays were built from steel rather than wood spars. The single-axle main undercarriage carried wheels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol Berkeley
The Bristol Berkeley was built to a British government specification for a single-engine day or night bomber. Three of these two-seat biplanes were built, but no contract for further production was awarded. Development In August 1923, British aircraft manufacturers were invited to submit designs to Air Ministry Specification 26/23, which called for a single Rolls-Royce Condor-engined two-seat day or night bomber. The Berkeley was Bristol's response, designed largely by W.T. Reid with finishing touches from Bristol's longtime chief designer, Frank Barnwell. It was a fabric-covered all-metal structured three-bay biplane, with equal span, unswept and unstaggered wings with Frise-type ailerons on the upper and lower planes. Structurally, the wings were of rolled steel and duralumin. The fuselage was built from steel tubes and had a rectangular cross section. The pilot sat forward of the leading edge of the wing in an open cockpit and the gunner/observer in a cockpit well aft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aerospace Companies Of The United Kingdom
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space R ...

Aircraft Propeller Manufacturers
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 jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Morane-Saulnier AV
Aéroplanes Morane-Saulnier was a French aircraft manufacturing company formed in October 1911 by Raymond Saulnier (1881–1964) and the Morane brothers, Léon (1885–1918) and Robert (1886–1968). The company was taken over and diversified in the 1960s. History Model development Morane-Saulnier's first product was the Morane-Borel monoplane, a development of a monoplane design produced by the Morane company (sometimes called Type A) in partnership with Gabriel Borel). Using a wing-warping mechanism for control, this was the type in which Jules Védrines won the Paris-Madrid race on May 26, 1911. Morane-Saulnier's first commercially successful design was the Morane-Saulnier G, a wire-braced shoulder-wing monoplane with wing warping. This led to the development of a series of aircraft and was very successful in racing and setting records. The Type G was a 2-seater, and was reduced slightly in size to produce the Morane-Saulnier H, a single-seater, and was given a faired ...

The Airscrew Company
The Airscrew Company Ltd (incorporating the Jicwood company) was a British manufacturing company based in Surrey manufacturing propeller (aircraft), propellers. History The Airscrew Company was established in Weybridge, Surrey, England in 1923 when John Dodds Titler bought the assets of Lang, Garnett and Company, otherwise known as the Lang Propeller Company of Riverside Works, Weybridge. Lang Propellers was based at Hamm Moor Lane and at its peak supplied wooden propeller (aircraft), propellers to nearly every aeroplane company in England. Alcock and Brown flew the Atlantic in a Vickers Vimy fitted with Lang propellers; a letter held at Chertsey Museum confirms this and one of these four-bladed propellers survives at Brooklands Museum. The Lang company was absorbed into another aeronautical enterprise and vacated its works in Surrey. The company manufactured 2-blade wooden propellers for the early Spitfires and Hurricanes. Airscrew became a limited company in 1931, and by 1938 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
