Supermarine 545
The Supermarine 545 was a supersonic jet fighter project designed by the British aircraft manufacturer Supermarine. A single aircraft was built, but remained unflown, largely due to the project having fallen out of political favour. The project commenced during the early 1950s in response to interest in transonic aircraft within the Royal Air Force. Supermarine, who was at the time engaged in the development of another front-line fighter, the Swift, decided to use this existing programme as the Type 545's starting point. Major differences from the proceeding Swift was the adoption of a crescent wing and a more powerful powerplant in the form of the reheated Rolls-Royce Avon turbojet engine; amongst its performance capabilities, Supermarine claimed that the aircraft would be readily capable of achieving Mach 1.3. During February 1952, the company received an order for a pair of prototypes to be built. However, by the time that the first was completed, the project had become poli ...

Hawker Aircraft
Hawker Aircraft Limited was a British aircraft manufacturer that was responsible for some of the most famous products in British aviation history. History Hawker had its roots in the aftermath of the First World War, which resulted in the bankruptcy of the Sopwith Aviation Company. Sopwith test pilot Harry Hawker and three others, including Thomas Sopwith, bought the assets of Sopwith and formed H.G. Hawker Engineering in 1920. In 1933, the company was renamed Hawker Aircraft Limited, and it took advantage of the Great Depression and a strong financial position to purchase the Gloster Aircraft Company in 1934. The next year, it merged with the engine and automotive company Armstrong Siddeley and its subsidiary, Armstrong Whitworth Aircraft, to form Hawker Siddeley Aircraft. This group also encompassed A. V. Roe and Company (Avro). The company continued to produce designs under the "Hawker" name as part of Hawker Siddeley Aircraft, which from 1955 was a division of Hawker S ...

ADEN Cannon
The Royal Small Arms Factory ADEN cannon (ADEN being an acronym for "Armament Development, Enfield") is a 30 mm revolver cannon used on many military aircraft, particularly those of the British Royal Air Force and Fleet Air Arm. Developed post-World War II primarily to meet British Air Ministry's requirement for increased lethality in aircraft armament, the cannon was fired electrically and is fully automatic once it is loaded. Design and development During World War II, the German firm Mauser began development of a radically new 20 mm autocannon using a motorised firing mechanism in order to improve the rate of fire. The weapon got the preliminary designation Mauser MG 213 and by the late-war period the design was beginning to mature. However the presence of large heavy bombers like the Boeing B-17 Flying Fortress and Avro Lancaster led to the need of up-arming ''Luftwaffe'' fighter aircraft with heavier cannons. Mauser responded to this by adapting the MaschinenGew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Aircraft Corporation
The British Aircraft Corporation (BAC) was a British aircraft manufacturer formed from the government-pressured merger of English Electric Aviation Ltd., Vickers-Armstrongs (Aircraft), the Bristol Aeroplane Company and Hunting Aircraft in 1960. Bristol, English Electric and Vickers became "parents" of BAC with shareholdings of 20%, 40% and 40% respectively. BAC in turn acquired the share capital of their aviation interests and 70% of Hunting Aircraft several months later. History Formation BAC's origins can be traced to a statement issued by the British government that it expected the various companies involved in the aircraft, guided weapons and engine industries to consolidate and merge with one another. Furthermore, the government also promised incentives to motivate such restructuring; the maintenance of government research and development spending and the guarantee of aid in launching "promising new types of civil aircraft". One particularly high-profile incentive was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hursley Park
Hursley House is an 18th-century Queen Anne style mansion in Hursley, near Winchester in the English county of Hampshire. The building is Grade II* listed. History The Hursley estate was bought by William Heathcote, MP from the daughters of Richard Cromwell. Cromwell had acquired the estate by marriage to the daughter of Richard Major, MP. Heathcote commissioned the present house to be built between 1721 and 1724, during the reign of George I, and was created a baronet in 1733. The estate descended in the Heathcote family to the 5th Baronet, whose widow sold it after his death in 1881 to Joseph Baxendale, the owner of the Pickfords logistics and removal company. He sold it in 1902 to Sir George Cooper whose wife, Mary Emma Smith, an American railways heiress from Chicago, commissioned architect Alexander Marshall Mackenzie to carry out extensive development work in 1902 to create the house that can be seen today. Sir George was created a baronet in 1905. During the First Wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Military Aircraft Serials
United Kingdom military aircraft serial numbers are aircraft registration numbers used to identify individual military aircraft in the United Kingdom (UK). All UK military aircraft are allocated and display a unique registration number. A unified registration number system, maintained initially by the Air Ministry (AM), and its successor the Ministry of Defence (MoD), is used for aircraft operated by the Royal Air Force (RAF), Fleet Air Arm (FAA), and Army Air Corps (AAC). Military aircraft operated by government agencies and civilian contractors (for example QinetiQ) are also assigned registration numbers from this system. When the Royal Flying Corps (RFC) was formed in 1912, its aircraft were identified by a letter/number system related to the manufacturer. The prefix 'A' was allocated to balloons of No.1 Company, Air Battalion, Royal Engineers, the prefix 'B' to aeroplanes of No.2 Company, and the prefix 'F' to aeroplanes of the Central Flying School.Bruce 1956, p.922 ...

Crescent Wing
The crescent wing is a fixed-wing aircraft configuration in which a swept wing has a greater sweep angle on the inboard section than the outboard, giving the wing a crescent shape. The planform attempts to reduce several unpleasant side-effects of the swept wing design, notably its tendency to "pitch-up", sometimes violently, when it nears a stall. Basic concept As an aircraft enters the transonic region close to the speed of sound, the acceleration of air over curved areas can cause the flow to go supersonic. This generates a shock wave and creates considerable drag, known as wave drag. The increase in drag is so rapid and powerful that it gives rise to the concept of a sound barrier. The speed at which this effect becomes noticeable, known as ''critical mach'', is based on the rate of curvature on the upper and lower surfaces; airfoils with greater curvature will have a lower critical Mach speed and thus suffer more heavily from wave drag. A wing designed for good transonic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Rule
The Whitcomb area rule, named after NACA engineer Richard Whitcomb and also called the transonic area rule, is a design procedure used to reduce an aircraft's drag at transonic speeds which occur between about Mach 0.75 and 1.2. For supersonic speeds a different procedure called the supersonic area rule, developed by NACA aerodynamicist Robert Jones, is used. Transonic is one of the most important speed ranges for commercial and military fixed-wing aircraft today, with transonic acceleration an important performance requirement for combat aircraft and which is improved by reductions in transonic drag. Description At high-subsonic flight speeds, the local speed of the airflow can reach the speed of sound where the flow accelerates around the aircraft body and wings. The speed at which this development occurs varies from aircraft to aircraft and is known as the critical Mach number. The resulting shock waves formed at these zones of sonic flow cause a sudden increase in drag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Air Ministry Specifications
This is a partial list of the British Air Ministry (AM) specifications for aircraft. A specification stemmed from an Operational Requirement, abbreviated "OR", describing what the aircraft would be used for. This in turn led to the specification itself, e.g. a two-engined fighter with four machine guns. So for example, OR.40 for a heavy bomber led to Specification B.12/36. Aircraft manufacturers would be invited to present design proposals to the ministry, following which prototypes of one or more of the proposals might be ordered for evaluation. On very rare occasions, a manufacturer would design and build an aircraft using their own money as a "private venture" (PV). This would then be offered to the ministry for evaluation. If the aircraft generated interest in the ministry or RAF due to performance or some other combination of features then the ministry might well issue a specification based on the private venture aircraft. The system of producing aircraft to a specification ra ... [...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] |
