Omega BS-12
The Omega BS-12 was a utility helicopter with high ground clearance designed to carry loads behind the cabin at, or near, the center of gravity. Design & development Bernard Sznycer, designer of the Sznycer SG-VI, the first helicopter certified in Canada, set up the Omega Aircraft Corporation, based at New Bedford, Massachusetts in December 1953, with himself as President and Chief Designer of the company. Omega's first design was a twin-engined flying crane / utility helicopter, intended to be inexpensive to produce and relatively cheap to operate. The helicopter was of conventional layout, with a single four-bladed lift rotor and a two bladed anti-torque rotor. Its fuselage was of pod-and-boom layout, with a small enclosed crew cabin forward connected to an uncovered steel tube tail boom. Cargo, either a slung load or in a pre-loaded pod, could be carried between the crew cabin and the undercarriage mainwheels, while it was planned to also provide a pod to carry passengers. I ...

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 Wikimedia project, 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 Magazine, 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".

1950s United States Helicopters
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.

Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying (magazine)
''Flying'', sometimes styled ''FLYING'', is an aviation magazine published since 1927 and called ''Popular Aviation'' prior to 1942, as well as ''Aeronautics'' for a brief period. It is read by pilots, aircraft owners, aviation enthusiasts and aviation-oriented executives in business, commercial and general aviation markets worldwide. It has the largest paid subscription, newsstand, and international circulation of any U.S.-based aviation magazine, according to its former publisher the Bonnier Corporation, and is promoted as "the world's most widely read aviation magazine". It is owned by digital media entrepreneur Craig Fuller. History The magazine first began publishing in 1927 as ''Popular Aviation'' soon after Charles Lindbergh's historic transatlantic flight. It was given the name ''Aeronautics'' briefly from 1929–1930 and was changed back to ''Popular Aviation'' until 1942, when it became ''Flying''. In June 2009, ''Flying'' owner, Hachette Filipacchi Media U.S., s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sikorsky S-64 Skycrane
The Sikorsky S-64 Skycrane is an American twin-engine heavy-lift helicopter. It is the civil version of the United States Army's CH-54 Tarhe. It is currently produced as the S-64 Aircrane by Erickson Inc. Development Under Sikorsky The Sikorsky S-64 was designed as an enlarged version of the prototype ''flying crane'' helicopter, the Sikorsky S-60. The S-64 had a six-blade main rotor and was powered by two Pratt & Whitney JFTD12A turboshaft engines. The prototype S-64 first flew on 9 May 1962 and was followed by two further examples for evaluation by the German armed forces. The Germans did not place an order, but the United States Army placed an initial order for six S-64A helicopters (with the designation YCH-54A Tarhe). Seven S-64E variants were built by Sikorsky for the civil market. Under Erickson Originally a Sikorsky Aircraft product, the type certificate and manufacturing rights were purchased from them by Erickson Air-Crane in 1992. Since that time, Eric ...

Boeing 502-W
The Boeing T50 (company designation Model 502) was a small turboshaft engine produced by Boeing. Based on Boeing's earlier Model 500 gas generator, the T50's main application was in the QH-50 DASH helicopter drone of the 1950s. An up-rated version designated Model 550 was developed to power the QH-50D and was given the military designation T50-BO-12.

Allison T63
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] |

Franklin 6AS-335
The Franklin O-335 (company designations variations on 6A and 6V) was an American air-cooled aircraft engine of the 1940s. The engine was of six-cylinder, horizontally-opposed layout and displaced . The power output of later variants was . Design and development These engines were commonly vertically mounted and used to power many early helicopters in the United States. They were closely related to the 2A4 and 4A4 2- and 4-cylinder engines. In various subtypes, the 6A4 remained in continuous production from 1945 to the time Franklin's United States operations ceased in 1975, with versions continuing in Polish production into the 1990s. In 1947 this engine was modified into a water-cooled version by the Tucker Car Corporation for use in the 1948 Tucker Sedan. Tucker liked the engine so much that he purchased the Aircooled Motors/Franklin Engine Company The Franklin Engine Company was an American manufacturer of aircraft engines. Its designs were used primarily in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
