Martin XB-48
The Martin XB-48 was an American medium jet bomber developed in the mid-1940s. It competed with the Boeing B-47 Stratojet, which proved to be a superior design, and was largely considered as a backup plan in case the B-47 ran into development problems. It never saw production or active duty, and only two prototypes, serial numbers 45-59585 and 45-59586, were built. Design and development In 1944, the U.S. War Department was aware of aviation advances in Germany and issued a requirement for a range of designs for medium bombers weighing from to more than . Other designs resulting from this competition, sometimes nicknamed "The Class of 45", included the North American XB-45 and the Convair XB-46. Production orders finally went to the North American B-45 Tornado, and even this airplane served only for a couple of years before again being replaced by the much more modern Boeing B-47 Stratojet, although the B-45 had the inherent performance – especially if it was not burdened wi ...

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".

Martin Aircraft
The Glenn L. Martin Company—also known as The Martin Company from 1957-1961—was an American aircraft and aerospace manufacturing company founded by aviation pioneer Glenn L. Martin, and operated between 1917-1961. The Martin Company produced many important aircraft for the defense of the US and allies, especially during World War II and the Cold War. During the 1950s and 60s, the Martin Company moved from the aircraft industry into the guided missile, space exploration, and space utilization industries. In 1961, the Martin Company merged with American-Marietta Corporation, a large industrial conglomerate, forming Martin Marietta Corporation. In 1995, Martin Marietta merged with aerospace giant Lockheed to form the Lockheed Martin Corporation."Lockheed Martin History." ''lockheedmartin.com.'' Retrieve ...

1940s United States Bomber Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 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.

Ilyushin Il-28
The Ilyushin Il-28 (russian: Илью́шин Ил-28; NATO reporting name: Beagle) is a jet aircraft, jet bomber of the immediate postwar period that was originally manufactured for the Soviet Air Forces. It was the Soviet Union's first such aircraft to enter large-scale production. It was also licence-built in China as the Harbin H-5. Total production in the USSR was 6,316 aircraft, and over 319 H-5s were built. Only 187 examples of the HJ-5 training variant were manufactured. In the 1990s hundreds remained in service with various air forces over 50 years after the Il-28 first appeared. The only H-5s in service currently are approximately 80 aircraft which operate with the Korean People's Air Force. The Il-28 has the USAF/DoD reporting name "Type 27"Parsch, Andreas and Aleksey V.

Retrieved: 21 August 2011. was the first Soviet jet-engined bomber to fly. It used four Lyulka TR-1 turbojets carried on short horizontal pylons ahead and below the wing. The engines did not meet their designed thrust ratings and their fuel consumption was higher than planned. These problems meant that the aircraft could not reach its required performance and it was cancelled on 22 September 1947.Němeček 1986, p. 170. Design and development The Council of Ministers ordered the Ilyushin design bureau on 12 February 1946 to begin work on a bomber that would use four of the new TR-1 jet engines. Experiences with the first generation of jet fighters had revealed unsuspected problems involved with high-speed flight and Ilyushin devoted much effort to mitigate them.

English Electric Canberra
The English Electric Canberra is a British first-generation, jet-powered medium bomber. It was developed by English Electric during the mid- to late 1940s in response to a 1944 Air Ministry requirement for a successor to the wartime de Havilland Mosquito fast bomber. Among the performance requirements for the type was an outstanding high-altitude bombing capability and high speed. These were partly accomplished by making use of newly developed jet-propulsion technology. When the Canberra was introduced to service with the Royal Air Force (RAF), the type's first operator, in May 1951, it became the service's first jet-powered bomber. In February 1951, a Canberra set another world record when it became the first jet aircraft to make a nonstop transatlantic flight. Throughout most of the 1950s, the Canberra could fly at a higher altitude than any other aircraft in the world, and in 1957, a Canberra established a world altitude record of .

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric J35
The General Electric/Allison J35 was the United States Air Force's first axial-flow (straight-through airflow) compressor jet engine. Originally developed by GE Aviation, General Electric (GE company designation TG-180) in parallel with the Frank Whittle, Whittle-based centrifugal compressor, centrifugal-flow Allison J33, J33, the J35 was a fairly simple turbojet, consisting of an eleven-stage axial-flow compressor and a single-stage turbine. With the afterburner, which most models carried, it produced a thrust of . Like the J33, the design of the J35 originated at General Electric, but major production was by the Allison Engine Company. Design and development While developing the General Electric T31, T31 axial turboprop in 1943 General Electric realized that they had the resources to design an axial flow turbojet at the same time as their centrifugal compressor, centrifugal-flow Allison J33, J33 engine. They recognized the axial would have more potential for the future and went ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
