Raoul Hafner
Raoul Hafner, (1905–1980) FEng, FRAes, was an Austrian-born British helicopter pioneer and engineer. He made a distinctive contribution to the British aerospace industry, particularly in the development of helicopters. Life Born in 1905, he was educated in Vienna, first at the university and then at technical college where he became interested in rotary-wing concept as a means of making aircraft land more slowly and safely. He obtained a post with the Austrian Air Traffic Company, but his heart was in helicopter design. He gave up his job to concentrate on helicopters, designing and building the Hafner Nagler R.I Revoplane in 1929 in collaboration with Bruno Nagler, then the similar Hafner Nagler R.II Revoplane in 1931.''Bristol Sycamore'' Heli Archive [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Collective Pitch
A helicopter pilot manipulates the helicopter flight controls to achieve and maintain controlled aerodynamic flight. Changes to the aircraft flight control system transmit mechanically to the rotor, producing aerodynamic effects on the rotor blades that make the helicopter move in a deliberate way. To tilt forward and back (pitch) or sideways (roll) requires that the controls alter the angle of attack of the main rotor blades ''cyclically'' during rotation, creating differing amounts of lift (force) at different points in the cycle. To increase or decrease overall lift requires that the controls alter the angle of attack for all blades ''collectively'' by equal amounts at the same time, resulting in ascent, descent, acceleration and deceleration. A typical helicopter has three flight control inputs—the cyclic stick, the collective lever, and the anti-torque pedals. Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a ''mixing uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

Bristol Sycamore
The Bristol Type 171 Sycamore was an early helicopter developed and built by the helicopter division of the Bristol Aeroplane Company. The name refers to the seeds of the sycamore tree, '' Acer pseudoplatanus'', which fall with a rotating motion. It has the distinction of being the first British helicopter to receive a certificate of airworthiness, as well as being the first British-designed helicopter to be introduced by and to serve with the Royal Air Force (RAF). Typically capable of seating up to three passengers, the type was often used as a transport for both passengers and cargo alike. In RAF service, the Sycamore was normally used in the search and rescue and casualty evacuation roles. The type proved the value of rotorcraft to easily traverse inhospitable or otherwise inaccessible terrain; the Sycamore made valuable contributions to British military activities during the Malayan Emergency, the Cyprus Emergency, and the Aden Emergency, in addition to other operations. ...

Bristol Aeroplane Company
The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. BAC went on to become a founding component of the nationalised British Aerospace, now BAE Systems. Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rotabuggy
The Hafner Rotabuggy (formally known as the Malcolm Rotaplane and as the "M.L. 10/42 Flying Jeep") was a British experimental aircraft that was essentially a Willys MB combined with a rotor kite, developed with the intention of producing a way of air-dropping off-road vehicles. Design and development It was designed by Raoul Hafner of the Airborne Forces Experimental Establishment (AFEE) after their development of the Rotachute enjoyed some success. The prototype was built by the R. Malcolm & Co. Ltdlater ML Aviation (also producer of the Malcolm hood) at White Waltham in 1942. Air Ministry specification 10/42 for a "Special Rotating Wing Glider" was used to identify the project.Meekcoms/Morgan 1994, p. 306 Initial testing showed that a Willys MB could be dropped from heights up to without damage to the vehicle. A diameter rotor was attached, along with a tail fairing and fins, but no rudders. Two men were required to pilot the aircraft: one to drive it as an automobile, ...

RAF Sherburn-in-Elmet
Sherburn-in-Elmet Airfield is located east of Sherburn in Elmet village and west of Selby, North Yorkshire, England. Pre-War and Wartime history In the 1920s, the Yorkshire Aeroplane Club began operating here. The novelist, pilot, and aeronautical engineer Nevil Shute was a member, and on the club's management committee. At the time, the club was flying de Havilland Moths. In his memoir, ''Slide Rule'', Shute records that ". . . the Yorkshire Club quickly attracted a fair cross-section of young Yorkshire men and women, so that a Sunday spent at the Club was a merry Sunday." He also met his future wife, Frances Mary Heaton, a physician, at the club. After establishing Airspeed Ltd., an aircraft manufacturing firm, he personally flew the first two test flights of the company's first aircraft here. It was a glider, known as the Tern, and was launched using a "very old Buick car" pulling a steel cable.Nevil Shute, "Slide Rule", London: Heinemann, 1954 During the Second World Wa ...

Airborne Forces Experimental Establishment
The Airborne Forces Experimental Establishment (AFEE) was a branch of the British Air Ministry, that researched and developed non-traditional airborne applications, such as gliders, rotary wing aircraft, and dropping of personnel and equipment by parachute, in the period 1942–1950. Formation (1942) On 15 February 1942, the Airborne Forces Experimental Establishment was formed as a reorganisation of the Airborne Forces Establishment, that itself was a September 1941 renaming of the Central Landing Establishment. The AFEE was initially based at RAF Ringway as part of No. 70 Group RAF, with two flying units, A Flight and B Flight. At Ringway, one of the existing projects was the Hafner Rotachute, a rotor kite (unpowered autogiro) that was planned to deliver an armed soldier to a battlefield more accurately and reliably than conventional parachute methods. During 1941, unmanned models had already completed ground-based tests plus some releases from aircraft in flight.Sturtivant 200 ...

Hafner Rotachute
The Hafner H.8 Rotachute was a British 1940s experimental one-man rotor kite designed by Raoul Hafner. Background The Rotachute was the eventual development of a concept devised by Raoul Hafner, an Austrian engineer who specialised in rotary wing design, and who had moved to the UK in 1933 to continue his research and development work. In 1940, he proposed the use of a single-place strap-on rotor kite in place of a conventional parachute, to deliver a soldier accurately to a battlefield. The proposal was made to the Air Ministry in the light of a shortage of silk for parachute manufacture. Hafner was briefly interned as an alien, but was released to pursue the feasibility of the idea at the Central Landing Establishment (CLE) located at RAF Ringway. In October 1940, work began on design and construction of rotor systems and scale models of rotor kites. The first models were made of wood and fabric, ballasted to represent a pilot, and had a rotor span of about 3 ft (0.91 m). ...

Internment
Internment is the imprisonment of people, commonly in large groups, without charges or intent to file charges. The term is especially used for the confinement "of enemy citizens in wartime or of terrorism suspects". Thus, while it can simply mean imprisonment, it tends to refer to preventive confinement rather than confinement ''after'' having been convicted of some crime. Use of these terms is subject to debate and political sensitivities. The word ''internment'' is also occasionally used to describe a neutral country's practice of detaining belligerent armed forces and equipment on its territory during times of war, under the Hague Convention of 1907. Interned persons may be held in prisons or in facilities known as internment camps (also known as concentration camps). The term ''concentration camp'' originates from the Spanish–Cuban Ten Years' War when Spanish forces detained Cuban civilians in camps in order to more easily combat guerrilla forces.

Rochester, Kent
Rochester ( ) is a town in the unitary authority of Medway, in Kent, England. It is at the lowest bridging point of the River Medway, about from London. The town forms a conurbation with neighbouring towns Chatham, Rainham, Strood and Gillingham. Rochester was a city until losing its status as one in 1998 following the forming of Medway and failing to protect its status as a city. There have been ongoing campaigns to reinstate the city status for Rochester. Rochester was for many years a favourite of Charles Dickens, who owned nearby Gads Hill Place, Higham, basing many of his novels on the area. The Diocese of Rochester, the second oldest in England, is centred on Rochester Cathedral and was responsible for founding a school, now ''The King's School'', in 604 AD, which is recognised as the second oldest continuously running school in the world. Rochester Castle, built by Bishop Gundulf of Rochester, has one of the best-preserved keeps in either England or France. During ...
