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. United States Department of War, 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. All of the bombers comprising the Class of '45 were transitional aircraft, which combined the power of turbojets with the aeronautical design of World War II, notably the unswept wings and tail surfaces. The XB-48 was no exception, as its round fuselage ... [...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 General Electric (GE company designation TG-180) in parallel with the Whittle-based centrifugal-flow 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 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-flow J33 engine. They recognized the axial would have more potential for the future and went ahead with the TG-180 engine. GE axial compressor designs were developed from the NACA 8-stage compressor. The en ...

Aircraft First Flown In 1947
An aircraft ( aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, whereas unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martin Aircraft
The Glenn L. Martin Company, also known as The Martin Company from 1917 to 1961, was an American aircraft and aerospace manufacturing company founded by aviation pioneer Glenn L. Martin. 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 1960s, 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 the Martin Marietta corporation. In turn, Martin Marietta in 1995 merged with aerospace giant Lockheed Corporation to form the Lockheed Martin corporation."Lockheed Martin History." ''lockheedmartin.com.'' Retrieved: Ju ...

1940s United States Bomber Aircraft
Year 194 ( CXCIV) was a common year starting on Tuesday 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. Events By place Roman Empire * Decimus Clodius Septimius Albinus Caesar became a Roman Consul. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria.

List Of Bomber Aircraft
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Ilyushin Il-28
The Ilyushin Il-28 (; NATO reporting name: Beagle) is a 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. 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.

Ilyushin Il-22
The Ilyushin Il-22, USAF/ DOD designation Type 10,Parsch, Andreas and Aleksey V. Martynov"Designations of Soviet and Russian Military Aircraft and Missiles."''designation-systems.net,'' 2008. 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 Flight altitude record, world altitude record of .
