Spitfire Helicopters Spitfire Mk.I
__NOTOC__ The Spitfire Mark I was a utility helicopter built in the United States in the late 1970s and intended for series production.Taylor 1989, p.839Simpson 1998, p.234Taylor 1977, p.411 In essence, the Mark I was an Enstrom F-28 that was modified to use an Allison 250 turboshaft engine and geared transmission in place of the original piston engine and system of vee belts. The resulting powerplant installation was lighter and more compact, which allowed for additional cargo or fuel. Spitfire Helicopters' parent company, Fetsko Aviation Sales and Transportation began work on the prototype in January 1976, and on a number of pre-production aircraft in February 1977. Fetsko displayed a mockup of the concept at the National Maintenance and Operations Meeting at Reading, Pennsylvania in June 1976.Field and Goodman 1976, p.33 The prototype (registered ''N4890'') first flew in December 1978. By May 1979, Spitfire had supplemental approval for the turbine conversionLambert 1979, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary figh ...

PZL-Świdnik
PZL-Świdnik S.A. (''Wytwórnia Sprzętu Komunikacyjnego PZL-Świdnik S.A.'') is the biggest helicopter manufacturer in Poland. Its main products are PZL W-3 Sokół and PZL SW-4 Puszczyk helicopters. In early 2010 the factory was acquired by AgustaWestland, today Leonardo. History History of plant establishment dating back to 1920, when in Lublin opened the first aircraft factory " Plage i Laśkiewicz". After World War II part of the senior instructors staff incorporated into the newly formed "Wytwórnia Sprzętu Komunikacyjnego". In 1951 a third national aerospace factory, WSK-Świdnik, was built in Świdnik, and in 1957 it was renamed to WSK PZL-Świdnik. Since 1956 it has become one of the world's major helicopter manufacturers, producing helicopters under the Soviet licence, starting with the SM-1 (Mil Mi-1). Świdnik was the main producer of the Mi-1 and exclusive producer of the widely used in the world Mil Mi-2. Since the late 1980s, Świdnik has been producing a Poli ...

Enstrom 480
The Enstrom 480 is a small, light helicopter produced by the Enstrom Helicopter Corporation.Apostolo, Giorgio: ''The Illustrated Encyclopedia of Helicopters'', pages 64-65. Bonanza Books, New York, 1984. Design and development In the 1980s the Enstrom Helicopter Company was producing two helicopters, both powered by horizontally-opposed piston engines. When the United States Army revealed a requirement for a turbine-powered training helicopter, the company designed a larger, turbine-powered version of its 280 Shark. The proposed unit was designated TH28 (TH for "training helicopter" derived from the 28(0), since the Army's proposal was NTH, "new training helicopter"). The Army contract effort was not successful, but the company effort looked promising enough that management committed to continue with a commercial version, which was introduced in 1993. Its power was provided by the C20W variant of the Rolls-Royce Model 250 turboshaft engine. Design The 480 fuselage consists of a ...

Málaga
Málaga (, ) is a municipality of Spain, capital of the Province of Málaga, in the autonomous community of Andalusia. With a population of 578,460 in 2020, it is the second-most populous city in Andalusia after Seville and the sixth most populous in Spain. It lies on the Costa del Sol (''Coast of the Sun'') of the Mediterranean, about east of the Strait of Gibraltar and about north of Africa. Málaga's history spans about 2,800 years, making it one of the oldest cities in Europe and one of the oldest continuously inhabited cities in the world. According to most scholars, it was founded about 770BC by the Phoenicians as ''Malaka'' ( xpu, 𐤌𐤋𐤊𐤀, ). From the 6th centuryBC the city was under the hegemony of Ancient Carthage, and from 218BC, it was ruled by the Roman Republic and then empire as ''Malaca'' (Latin). After the fall of the empire and the end of Visigothic rule, it was under Islamic rule as ''Mālaqah'' ( ar, مالقة) for 800 years, but in 1487, the ...

Mil Mi-2
The Mil Mi-2 (NATO reporting name Hoplite) is a small, three rotor blade Soviet-designed multi-purpose helicopter developed by the Mil Moscow Helicopter Plant designed in the early 1960s, and produced exclusively by WSK "PZL-Świdnik" in Poland. Design and development The Mi-2 was produced exclusively in Poland, in the WSK "PZL-Świdnik" factory in Świdnik. The first production helicopter in the Soviet Union was the Mil Mi-1, modelled along the lines of the S-51 and Bristol Sycamore and flown by Mikhail Mil's bureau in September 1948. During the 1950s it became evident, and confirmed by American and French development, that helicopters could be greatly improved with turbine engines. S. P. Isotov developed the GTD-350 engine and Mil used two of these in the far superior Mi-2. The twin shaft-turbine engines used in the Mi-2 develop 40% more power than the Mi-1's piston engines, for barely half the engine weight, with the result that the payload was more than doubled. The Mi- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Spitfire Mark II
__NOTOC__ The Spitfire Mark II, later given the name Tigershark,"Spitfire and Sodian about to sign?", p.1208 was a utility helicopter built in the United States in the late 1970s and intended for series production.Taylor 1989, p.839Simpson 1998, p.234Taylor 1977, p.411 It was a further evolution of the Spitfire Mark I design, a turbine-powered conversion of the Enstrom F-28. Although airframe changes on the Mark I had been minimal, the Mark II had a substantially redesigned fuselage that rearranged the F-28's 2+2 seating to move the pilot's seat forward in the nose by itself and add a bench seat for three passengers abreast behind it."Spitfire prepares new model production", p.12Lambert 1977, p.404 The leftmost seat on the bench could be fitted with dual controls. The fuselage was lengthened, and the powerplant installation (the same Allison 250 used on the Mark I) was mounted well to the rear. The Mark II still used the dynamic components of the F-28, p ...
