Mil Mi-34
The Mil Mi-34 (NATO reporting name: Hermit) is a light helicopter designed by the Mil Moscow Helicopter Plant in either a two or four seat configuration for utility and training. It was first flown on 17 November 1986 and introduced at the Paris Air Show in 1987. The Mi-34 entered production in 1993, and is capable of performing aerobatic manoeuvres, including rolls and loops. Variants * Mi-34SJane's (2004–05) indicates that the Mi-34S is the base design and that prior to 1999, all marketing literature referred to the Mi-34 using the Mi-34C designation. The ''S'' or ''C'' suffixes were used to indicate the aircraft's certification by the Interstate Aviation Committee. The Russian word for ''certified'' (russian: Сертифицированные) begins with the Cyrillic ''C'', which is romanized as the letter ''S''. – four seat production model powered by a 239 kW (325 hp) Vedeneyev (VOKBM) M-14V-26V nine-cylinder, air-cooled, radial engine mounted sideways in th ...

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 ...

Allison 250-C20R
The Allison Model 250, now known as the Rolls-Royce M250, (US military designations T63 and T703) is a highly successful turboshaft engine family, originally developed by the Allison Engine Company in the early 1960s. The Model 250 has been produced by Rolls-Royce since it acquired Allison in 1995. Development In 1958, the Detroit Diesel Allison division of General Motors was chosen by the US Army to develop a new light turbine engine to power a "Light Observation Aircraft" (LOA), to replace the Cessna O-1A Bird Dog. At this stage the US Army was unsure whether to have a fixed- or rotary-wing aircraft, so Allison was instructed to consider both applications. Design studies undertaken considered a wide range of possible mechanical configurations for the turboprop/turboshaft. These studies culminated in the testing of the first prototype engine, designated YT63-A-3, in April 1959. In 1960, the US Army settled for a rotary wing platform. The YT63-A-3 first flew in a variant of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PZL SW-4
PZL (''Państwowe Zakłady Lotnicze'' - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, and a brand of their aircraft. Based in Warsaw between 1928 and 1939, PZL introduced a variety of well-regarded aircraft, most notably the PZL P.11 fighter, the PZL.23 Karaś light bomber, and the PZL.37 Łoś medium bomber. In the post-war era, aerospace factories in Poland were initially run under the name WSK (Transport Equipment Manufacturing Plant), but returned to adopt PZL acronym in late 1950s. This was used as a common aircraft brand and later as a part of names of several Polish state-owned aerospace manufacturers referring to PZL traditions, and belonging to the ''Zjednoczenie Przemysłu Lotniczego i Silnikowego PZL'' - PZL Aircraft and Engine Industry Union. Among the better-known products during this period is the PZL TS-11 Iskra jet trainer and PZL-104 Wilga STOL utility aircraft. After the fall of communism in Poland in 1989, these ma ...

MD Helicopters MD 500
The MD Helicopters MD 500 series is an American family of light utility civilian and military helicopters. The MD 500 was developed from the Hughes 500, a civilian version of the US Army's OH-6A Cayuse/Loach. The series currently includes the MD 500E, MD 520N, and MD 530F. The MD 500 was initially produced by Hughes Helicopters as the ''Hughes 500''. Since being introduced in 1967, numerous models have been produced, often featuring a more powerful engine or a five-bladed main rotor in place of the original four-blade counterpart. The MD 500 has been commonly used for utility work, particularly the ''MD 530F''; it has also proven to be popular with law enforcement agencies. Production of the type was continued into the twenty-first century by Hughes' successor companies, McDonnell Douglas Helicopter Systems, and subsequently MD Helicopters. While the MD 500 series has been largely operated by civil customers, it has occasionally seen military use, even to the extent of performi ...

Kazan Ansat
The Kazan Ansat is a Russian light, multipurpose helicopter manufactured by Kazan Helicopters. History Kazan Helicopters in Kazan, Tatarstan, Russia has been one of the main Russian manufacturers of helicopters of the Mikhail Mil bureau design. In the 1990s management realized that there would be a need for light helicopters in Russia, as the fleet of standard Mi-2s was getting older, and the design itself became obsolete. The Mi-2 was the lightest helicopter in large-scale use in the former USSR, despite being larger than most light Western helicopters. At first Kazan Helicopters wanted to develop a helicopter based on the AS 350 Ecureuil in cooperation with Eurocopter, but it failed. As a result, in 1993 Kazan Helicopters organized its own design bureau in order to create a new helicopter (the bureau was officially certified by the Russian authorities in January 1997, designer Valery Dvoeglazov). The helicopter was named ''Ansat'' (meaning "light", "simple" or "easy" in the Ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bell 206
The Bell 206 is a family of two-bladed, single- and twin-engined helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec, plant. Originally developed as the Bell YOH-4 for the United States Army's Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation "B06" is used on flight plans for the JetRanger and LongRanger, and the designation "B06T" is used for the twin-engined TwinRangers. Development Origins and JetRanger On October 14, 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a req ...

Nigerian Air Force
The Nigerian Air Force (NAF) is the air branch of the Nigerian Armed Forces. It is the youngest branch of the Nigerian Armed Forces. It is one of the largest in Africa, consisting of about 15,000 personnel and aircraft including eight Chinese Chengdu F-7s, 12 Dassault-Dornier Alpha Jets, three JF-17 Thunder Block II and 12 Super Tucano aircraft, 24 M-346 FAs on order, Helicopter gunships, armed attack drones, and military transport aircraft. History Although an Air Force was originally proposed in 1958, many lawmakers preferred to rely on the United Kingdom for air defense. But during peacekeeping operations in Congo and Tanganyika, the Nigerian Army had no air transport of its own, and so in 1962, the government began to recruit cadets for pilot training in various foreign countries, with the first ten being taught by the Egyptian Air Force. 1960s The Nigerian Air Force was formally established on 18 April 1964 with the passage of the Air Force Act 1964 by the National Ass ...
