Scottish Aviation Pioneer
The Scottish Aviation Pioneer was an STOL aircraft manufactured by Scottish Aviation in Scotland. It was used for casualty evacuation and communications and could accommodate a pilot and up to four passengers. Design and development The Pioneer was planned to meet the requirements of Air Ministry Specification A.4/45 for a light communication aircraft. The three-seat prototype A.4/45, powered by a 240 hp de Havilland Gipsy Queen was a three-seat high-wing cabin monoplane. Four prototypes were ordered, under the name "Scottish Aviation Prestwick Pioneer" (Serials ''VL515, VL516, VL517'', and ''VL518''). In the event, only the first two were completed. The prototype aircraft (VL515) first flew in 1947. The use of the Gipsy Queen engine resulted in disappointing performance, and so the A.4/45 was not ordered by the RAF. Scottish Aviation decided instead to produce a civil version. This was achieved by fitting the two prototypes (VL515 and VL516) with new, more powerful ...

Malayan Emergency
The Malayan Emergency, also known as the Anti–British National Liberation War was a guerrilla war fought in British Malaya between communist pro-independence fighters of the Malayan National Liberation Army (MNLA) and the military forces of the British Empire and Commonwealth. The communists fought to win independence for Malaya from the British Empire and to establish a socialist economy, while the Commonwealth forces fought to combat communism and protect British economic and colonial interests.Siver, Christi L. "The other forgotten war: understanding atrocities during the Malayan Emergency." In APSA 2009 Toronto Meeting Paper. 2009., p.36 The conflict was called the "Anti–British National Liberation War" by the MNLA, but an "Emergency" by the British, as London-based insurers would not have paid out in instances of civil wars. On 17 June 1948, Britain declared a state of emergency in Malaya following attacks on plantations, which in turn were revenge attacks for the ...

STOL Aircraft
A short takeoff and landing (STOL) aircraft is a conventional fixed-wing aircraft that has short runway requirements for takeoff and landing. Many STOL-designed aircraft also feature various arrangements for use on airstrips with harsh conditions (such as high altitude or ice). STOL aircraft, including those used in scheduled passenger airline operations, have also been operated from STOLport airfields which feature short runways. Design considerations Many fixed-wing STOL aircraft are bush planes, though some, like the de Havilland Canada Dash-7, are designed for use on prepared airstrips; likewise, many STOL aircraft are taildraggers, though there are exceptions like the PAC P-750 XSTOL, the Quest Kodiak, the de Havilland Canada DHC-6 Twin Otter and the Peterson 260SE. Autogyros also have STOL capability, needing a short ground roll to get airborne, but capable of a near-zero ground roll when landing. Runway length requirement is a function of the square of the minimum fly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1950 Establishments In Scotland
Year 195 ( CXCV) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Helio Courier
The Helio Courier is a cantilever high-wing light STOL utility aircraft designed in 1949. Around 500 of these aircraft were manufactured in Pittsburg, Kansas, from 1954 until 1974 by the Helio Aircraft Company. The design featured four leading edge slats that deployed automatically, and large trailing edge flaps. The engine was the 295 hp Lycoming GO-480, which had a gearbox that lowered the output RPM and allowed for the use of a large three-bladed propeller to further improve takeoff performance. Couriers were famous for their takeoffs, which often took only a few plane lengths and then climbed at very high angles. During airshow demonstrations, it was common for the aircraft to actually take off across a 100 - 200 foot wide runway. The geared engine, however, required constant maintenance and was a major downside to the design. During the early 1980s, new owners (Helio Aircraft Ltd.) made an attempt to build new aircraft with direct-drive Lycoming engines, to replace ...

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Sultan Of Oman's Air Force
The Royal Air Force of Oman ( ar, سلاح الجو السلطاني عمان, Silāḥ al-Jaww as-Sulṭāniy ‘Umān or RAFO) is the air arm of the Armed Forces of Oman. History Sultan of Oman's Air Force era The Sultan of Oman's Air Force (SOAF) was formed with British personnel and aircraft in March 1959. The first aircraft were two Scottish Aviation Pioneers transferred from the Royal Air Force. The first armed aircraft was the Percival Provost T52. In 1968 the SOAF received the first of 24 BAC Strikemaster jet trainer and light strike aircraft for operation against insurgents in the Dhofar region. In 1974 the SOAF was expanded with orders for the Britten Norman Defender, BAC One-Eleven, BAC VC10 and 32 Hawker Hunter ground attack aircraft. In 1977 Jaguar International joined the SOAF, followed in the 1980s by the BAe Hawk. Royal Air Force of Oman era In 1990 the SOAF was renamed the Royal Air Force of Oman (RAFO).

Royal Malaysian Air Force
The Royal Malaysian Air Force (RMAF, ms, Tentera Udara Diraja Malaysia; TUDM; Jawi: ) was formed on 2 June 1958 as the Royal Federation of Malaya Air Force (; ). However, its roots can be traced back to the Malayan Auxiliary Air Force formations of the British Royal Air Force in then-colonial British Malaya. The Royal Malaysian Air Force operates a mix of modern American, European and Russian-made aircraft. History Early years The Malaysian air forces trace their lineage to the Malayan Auxiliary Air Force formations of the Royal Air Force (RAF) formed in 1934. They later transformed into the Straits Settlements Volunteer Air Force (SSVAF) and the Malayan Volunteers Air Force (MVAF) formed in 1940 and dissolved in 1942 during the height of the Japanese advance over Malaya. The latter was re-established in 1950 in time for the Malayan Emergency and contributed very much to the war effort. On 2 June 1958 the MVAF finally became the Royal Federation of Malaya Air Force (RF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Ceylon Air Force
The Sri Lanka Air Force (SLAF) ( si, ශ්රි ලංකා ගුවන් හමුදාව, Śrī Laṃkā guwan hamudāva; ta, இலங்கை விமானப்படை, Ilaṅkai vimāṉappaṭai) is the air arm and the youngest of the Sri Lanka Armed Forces. It was founded in 1951 as the Royal Ceylon Air Force (RCyAF) with the assistance of the Royal Air Force (RAF). The SLAF played a major role throughout the Sri Lankan Civil War. The SLAF operates more than 160 aircraft and has a projected trained strength of 27,400 airmen and 1,300 officers, who are from both regular and reserve service. The Sri Lanka Air Force has expanded to specialise mainly in providing air-support to ground forces, troop landing, and carrying out airstrikes on rebel-held areas in the Northern and Eastern theatres, but is also capable of high- and low-level air defence.
