Handley Page HP.22
The Handley Page H.P.22 and H.P.23 were single-seat sport monoplanes produced for the 1923 Lympne light aircraft trials. They were not successful. Development With prizes worth a total of £2,150, the Lympne light aircraft competition of October 1923 attracted 28 entries including the Avro 558, de Havilland Humming Bird and Gloster Gannet. Handley Page provided three contestants, at that time without a company type letter but bearing the competition numbers 23, 25 and 26. These were designed by W.H Sayers, technical editor of ''The Aeroplane'' and owed much to a glider that he, along with Frank Courtney and Maurice Wright had designed and built for the glider competition held at Itford Hill the previous year. In the later 1920s, when Handley Page began using the familiar H.P. numbering system they retrospectively named the initially similar no.23 and 25 the H.P.22 and no.26 became the H.P.23. As originally completed, all three aircraft had much in common. They had almos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Handley Page
Handley Page Limited was a British aerospace manufacturer. Founded by Frederick Handley Page (later Sir Frederick) in 1909, it was the United Kingdom's first publicly traded aircraft manufacturing company. It went into voluntary liquidation and ceased to exist in 1970. The company, based at Radlett Aerodrome in Hertfordshire, was noted for its pioneering role in aviation history and for producing heavy bombers and large airliners. History Frederick Handley Page first experimented with and built several biplanes and monoplanes at premises in Woolwich, Fambridge and Barking Creek. His company, founded on 17 June 1909, became the first British public company to build aircraft. In 1912, Handley Page established an aircraft factory at Cricklewood after moving from Barking. Aircraft were built there, and flown from the company's adjacent airfield known as Cricklewood Aerodrome, which was later used by Handley Page Transport. The factory was later sold off to Oswald Stoll and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lympne Light Aircraft Trials
The Lympne Light Aircraft Trials were held to encourage the development of practical light aircraft for private ownership, with a strong but not exclusive emphasis on fuel economy. They were held in 1923, 1924 and 1926. Each year saw different restrictions on engine size, framed initially in terms of capacity and then weight. The ''Daily Mail'' newspaper provided cash prizes throughout though the initiating donation came from the Duke of Sutherland. The Air Ministry were prize givers in the 1924 event. The trials were held at Lympne in Kent, England. The background The Lympne events had their origin in the post-World War I state of aviation in Britain and in Germany. Military aircraft production stopped immediately after the war ended. In Britain there were large stocks of surplus aircraft available at low prices, making it hard for manufacturers to develop new models. Airlines were only slowly emerging, largely using converted military aeroplanes and having not found a certain eco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avro 558
The Avro 558 was a British single-engined ultralight biplane built by Avro at Hamble Aerodrome. Design and development The Avro 558 was designed for the 1923 light aircraft trials for single-seaters at Lympne Aerodrome. Two Avro 558 biplanes were built, they were biplanes powered by motorcycle engines (one with a B&H twin-cylinder air-cooled engine, the second with a 500 cc Douglas engine). The first aircraft was modified with a 698 cc (42.6 in³) Blackburne Tomtit and both had modifications to the landing gear. Operational history The aircraft did not win the competition, but the second aircraft went on to establish a world record for its class of aircraft of 13,850 ft (4,222 m) over Lympne on 13 October 1923.Jackson 1974, p.292. It is not known what happened to the two aircraft, not having been reported since 1923.

De Havilland Humming Bird
The de Havilland DH.53 Humming Bird is a British single-seat, single-engine, low-wing monoplane light aircraft first flown in the 1920s. Design and development In response to the ''Daily Mail'' Light Aeroplane Competition of 1923 de Havilland built two DH.53s which were named ''Humming Bird'' and ''Sylvia II''. The DH.53 was a low-wing single-seat monoplane powered by a Douglas motorcycle engine. At Lympne, in October 1923, the DH.53s did not win any prizes but gave an impressive performance. The Air Ministry became interested in the design and ordered eight in 1924 as communications and training aircraft for the Royal Air Force. Early in 1924 twelve aircraft were built at Stag Lane Aerodrome and were named Humming Bird after the first prototype. Eight aircraft were for the Air Ministry order, three were for export to Australia, and one was exported to Aero in Prague. One further aircraft was later built for an order from Russia. The production aircraft were powered by a B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloster Gannet
The Gloster Gannet was a single-seat single-engined light aircraft built by the Gloucestershire Aircraft Company Limited of Cheltenham, United Kingdom, to compete in the 1923 Lympne Trials. Engine development problems prevented it from taking part. Development In 1923 the Royal Aero Club (RAeC) organised what became known as the Lympne light aircraft trials after the airfield where they were based, though the RAeC referred to the competing aircraft as ''motor-gliders''. The intention was to develop economical private aviation, so the engine size was limited to 750 cc with immediate consequences for aircraft size and weight. Various sponsors provided attractive prizes, particularly the total of £1500 jointly from the Duke of Sutherland and the Daily Mail. The event took place from 8–13 October 1923. The Gannet was Gloster's intended entry. It was a small, single-bay biplane, one of the smallest aircraft built in Britain. It was powered by a specially designed Card ...

ABC Motorcycles
ABC motorcycles was a British motorcycle manufacturer established in 1914 by Ronald Charteris in London. Several British motorcycle firms started up with the name "ABC", including Sopwith. The All British Engine Company Ltd. of London was founded in 1912 and later changed to ABC Motors Ltd. With chief engineer Granville Bradshaw, Charteris built a range of engines throughout the First World War. From 1913 ABC produced motorcycle engines. In 1918, ABC made a motorcycle with a 400 cc flat-twin engine mounted with its cylinders across the frame, several years before BMW adapted the design. Bradshaw challenged BMW's use of his patented design in 1926. In 1919 ABC also produced the Scootamota – an early motor scooter. The company stopped producing motorcycles after 1923 because of competition from cheaper manufacturers. Development ABC had always had a close association with the Sopwith aircraft company. They were both at Brooklands and in 1912 a Sopwith with an ABC eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackburne (motorcycles)
Blackburne was a trade name of Burney and Blackburne Limited a British manufacturer of motorcycles from 1913 to 1922 at Tongham near Farnham, Surrey. They were also a major supplier of engines to other motor cycle and light car makers and continued to make these until 1937. Burney and Blackburne also made small aircraft engines. Blackburne Motorcycles The origins of the Blackburne motorcycle engine start with Geoffrey de Havilland, who had designed and built a motor cycle before he became interested in aviation. In about 1905 he sold the designs and patterns to two student friends for £5 when he was short of money, and they went on to form the Blackburne engine company. A patent for adjustable belt pulleys for motorcycles dating back to 1912, shows Cecil Stanley Burney, Edward Alexander (Alick) Burney, and pioneer aviator Harold Blackburn trading as Burney and Blackburne (not Blackburn), operating from Northchurch, Berkhamsted. They were incorporated shortly afterwards as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Ministry
The Air Ministry was a department of the Government of the United Kingdom with the responsibility of managing the affairs of the Royal Air Force, that existed from 1918 to 1964. It was under the political authority of the Secretary of State for Air. Organisations before the Air Ministry The Air Committee On 13 April 1912, less than two weeks after the creation of the Royal Flying Corps (which initially consisted of both a naval and a military wing), an Air Committee was established to act as an intermediary between the Admiralty and the War Office in matters relating to aviation. The new Air Committee was composed of representatives of the two war ministries, and although it could make recommendations, it lacked executive authority. The recommendations of the Air Committee had to be ratified by the Admiralty Board and the Imperial General Staff and, in consequence, the Committee was not particularly effective. The increasing separation of army and naval aviation from 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
