Monospar
The General Aircraft Monospar was a 1930s British family of touring and utility aircraft built by General Aircraft Ltd (GAL). Design and development In 1929, the Monospar Company Ltd was formed to pursue new techniques of designing cantilever wings, based on the work of Swiss engineer Helmuth J. Stieger, who headed the company. Helmuth John Stieger was born in Zurich in 1902, and educated at the Swiss Federal Polytechnic, and then at the Imperial College of Science in London. While working as a designer for William Beardmore and Company, he formed his own ideas about wing design, and evolved an improved method of building and stressing wings, for which he was later granted a British Patent in December 1927. The principle behind this Patent No. 306,220 was that the wing needed only one spar with torsion loads resisted by an efficient system of strong compression struts, with triangulated bracing in the form of thin wires. The design was revolutionary and very light for its str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monospar ST-25
The General Aircraft Monospar ST-25 was a British 1930s light twin-engined utility aircraft. Design and development The Monospar ST-25 was a low-wing cantilever monoplane with a fabric-covered metal structure. The monospar name came from the use of a single spar in the wing structure, that had been developed by H J Stieger. The cabin was enclosed with five seats. It was based on the GAL Monospar ST-10, with the addition of a folding seat for a fifth passenger, extra side windows, and the addition of a radio receiver. On 19 June 1935, the prototype (G-ADIV) made its first flight at Hanworth Air Park. It was designated Monospar ST-25 Jubilee, to honour the 25th anniversary of the reign of King George V.Jackson 1973, pp. 215–220 Operational history *The last flying Monospar ST-25 (ZK-AFF), of Piet Van Asch, the owner of New Zealand Aerial Mapping Ltd, was lost in 1986 in a hangar fire. *The last surviving Monospar ST-25 (OY-DAZ), an ST-25 Ambulance, was fully restored during 198 ...

General Aircraft Ltd
General Aircraft Limited was a British aircraft manufacturer from its formation in 1931 to amalgamation with Blackburn Aircraft in 1949 to become Blackburn and General. Its main products were military gliders and light transport aircraft. History On 27 February 1931, General Aircraft Limited (GAL) was formed to undertake production of aircraft using the 'monospar' wing designs of the Mono-spar Company Ltd. Both firms were headed by Helmut J. Stieger, the Swiss inventor of the technique. GAL produced about 28 examples of the Monospar series of twin-engined light transport aircraft at Croydon Aerodrome between 1932 and 1934. In October 1934, both companies were re-capitalised by investment group British Pacific Trust, and were re-formed in a new company also named General Aircraft Limited. Also included in the new company were the assets of National Flying Services Ltd, the owner of London Air Park, plus adjoining industrial premises built in 1917 by Whitehead Aircraft Ltd. In e ...

Spanish Republican Air Force
The Spanish Republican Air Force was the air arm of the Armed Forces of the Second Spanish Republic, the legally established government of Spain between 1931 and 1939. Initially divided into two branches: Military Aeronautics ('' Aeronáutica Militar'') and Naval Aeronautics ( ''Aeronáutica Naval''), the Republican Air Force became the Air Forces of the Spanish Republic, ''Fuerzas Aéreas de la República Española'' (FARE), also known as ''Arma de Aviación'', after it was reorganized following the restructuring of the Republican Armed Forces in September 1936, at the beginning of the Spanish Civil War. This defunct Air Force is largely known for the intense action it saw during the Civil War, from July 1936 till its disbandment in 1939. The Spanish Republican Air Force was popularly known as ''"La Gloriosa"'' (The Glorious One). But, according to some historians, the command structure of the Spanish loyalist forces was marred by ineptitude and lack of decision-making througho ...

General Aircraft Croydon
__NOTOC__ The General Aircraft ST-18 Croydon was a 1930s British cabin monoplane built by General Aircraft Limited. Development Following the mixed success of the earlier Monospar family of aircraft, the company designed a ten-seat light transport, the ST-18 (later named Croydon). Due to the longer-span wing, it was not a cantilever ''monospar'' wing but had to be fitted with bracing struts. The ST-18 was a low-wing monoplane, with a conventional tail unit and tailwheel landing gear, and hydraulically retractable main gear. It was powered by two Pratt & Whitney Wasp Junior radial engines mounted on the wing leading edges. It had a crew of three, and a cabin for ten passengers, a toilet and baggage compartment.Jackson (1974), p. 310 Operational history On 16 November 1935, the sole aircraft (T22, later G-AECB) first flew at Hanworth Aerodrome, piloted by Harry M. Schofield. It performed well, but did not attract any orders, so the aircraft was prepared to establish a record fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's Cup Air Race
The King's Cup air race 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 prev ... is a British Handicapping, 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, 1 ...

De Havilland Gipsy Major
The de Havilland Gipsy Major or Gipsy IIIA is a four-cylinder, air-cooled, inverted inline engine used in a variety of light aircraft produced in the 1930s, including the famous Tiger Moth biplane. Many Gipsy Major engines still power vintage aircraft types. Engines were produced by de Havilland in the UK and by the Australian arm of the company, de Havilland Australia, the latter modifying the design to use imperial measures rather than the original metric measurements. Design and development The engine was a slightly modified Gipsy III, which was effectively a de Havilland Gipsy engine modified to run inverted so that the cylinders pointed downwards below the crankcase. The Major was also bored-out (118 mm from 114 mm) compared to the Gipsy III, increasing displacement from 5 L to 6.1 L. The inverted configuration allowed the propeller shaft to be kept in a high position without having the cylinders blocking the pilot's forward view over the nose of the airc ...

Pobjoy Niagara
The Pobjoy Niagara is a British seven-cylinder, air-cooled, radial, aero-engine first produced in 1934. The design ran at higher speeds than conventional engines, and used reduction gearing to lower the speed of the propeller. This led to a noticeable off-centre mounting for the propeller. The Niagara was a popular engine for light and experimental aircraft, well regarded due to its small diameter, smooth operation, low noise and innovative engineering. Variants ;Niagara I :Bore/stroke 77 x 87 mm (3.03 x 3.43 in), swept volume 2,835 cc (173 cu in). Compression 6.25:1, gearing 0.47:1.

London Air Park
London Air Park, also known as Hanworth Air Park, was a grass airfield in the grounds of Hanworth Park House, operational 1917–1919 and 1929–1947. It was on the southeastern edge of Feltham, now part of the London Borough of Hounslow. In the 1930s, it was best known as a centre for private flying, society events, visits by the Graf Zeppelin airship, and for aircraft manufacture by the Whitehead Aircraft Company during World War I and General Aircraft Limited (GAL) 1934–1949; in total over 1,650 aircraft were built here. Hanworth Park House In 1797, the manor house was destroyed by fire, leaving only the stable block, which survives today as flats, plus the coach house, which was converted into homes. c. 1799, a new house was built on the same site known as Hanworth House. In 1827, the house and estate of c. 680 acres (known as Hanworth Great Park), including three farms was sold outright to Henry Perkins. During the 1830s, the current building known as Hanworth Park Hous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
