Jet Age
The Jet Age is a period in the history of aviation defined by the advent of aircraft powered by jet turbine engines, and by the social change this brought about. Jet airliners were able to fly much higher, faster, and farther than older pistonpowered propliners, making transcontinental and intercontinental travel considerably faster and easier: for example, aircraft leaving North America and crossing the Atlantic Ocean (and later, the Pacific Ocean) could now fly to their destinations non-stop, making much of the world accessible within a single day's travel for the first time. Since large jetliners could also carry more passengers than piston-powered airliners, air fares also declined (relative to inflation), so people from a greater range of socioeconomic classes could afford to travel outside their own countries. Besides the pure jet, the turbine-driven propeller engines offered improvements of the piston engine delivering a smoother ride and better fuel efficiency. On ...

Lockheed Corporation
The Lockheed Corporation was an American aerospace manufacturer. Lockheed was founded in 1926 and later merged with Martin Marietta to form Lockheed Martin in 1995. Its founder, Allan Lockheed, had earlier founded the similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. History Origins Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed a prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I. Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles. On December 13, 1926, Allan Lockheed, Jack Northrop, John Northrop, Kenn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sud Aviation Caravelle
The Sud Aviation SE 210 Caravelle is a French jet airliner produced by Sud Aviation. It was developed by SNCASE in the early 1950s and made its maiden flight on 27 May 1955. It included some de Havilland designs and components developed for the de Havilland Comet. SNCASE merged into the larger Sud Aviation conglomerate before the aircraft entered revenue service on 26 April 1959 with Scandinavian Airlines System (SAS); 282 were built until production ended in 1972. It was ordered by airlines on every continent and operated until its retirement in 2005. The short-range, five-abreast airliner is powered by two aft-mounted Rolls-Royce Avon turbojet engines, allowing a clean low wing. The configuration was later retained in many narrow-body aircraft and regional jets. The initial I, III and VI variants could seat 90 to 99 passengers over . The later, slightly longer 10/11 variants could seat 99 to 118 passengers over and were powered by Pratt & Whitney JT8D low-bypass tu ...

Douglas DC-8
The Douglas DC-8 (sometimes McDonnell Douglas DC-8) is a long-range narrow-body airliner built by the American Douglas Aircraft Company. After losing the May 1954 US Air Force tanker competition to the Boeing KC-135, Douglas announced in July 1955 its derived jetliner project. In October 1955, Pan Am made the first order along with the competing Boeing 707, and many other airlines followed. The first DC-8 was rolled out in Long Beach Airport on April 9, 1958, and flew for the first time on May 30. FAA certification was achieved in August 1959 and the DC-8 entered service with Delta Air Lines on September 18. The six-abreast, low wing airliner was a four-engined jet aircraft with initial variants being long. The DC-8-10 was powered by Pratt & Whitney JT3C turbojets and had a MTOW, the DC-8-20 had more powerful JT4A turbojets for a MTOW. The intercontinental models had more fuel capacity and up to MTOW, powered by JT4As for the Series 30 and by Rolls-Royce Conway ...

Boeing 707
The Boeing 707 is an American, long-range, narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes. Developed from the Boeing 367-80 prototype first flown in 1954, the initial first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958. With versions produced until 1979, the 707 was a swept wing, quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models. Although it was not the first commercial jetliner in service, the 707 was the first to be widespread and is often credited with beginning the Jet Age. It dominated passenger air transport in the 1960s, and remained common through the 1970s, on domestic, transcontinental, and transatlantic flights, as well as cargo and military applications. It established Boeing as a dominant airliner manufacturer with its 7x7 series. The initial, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tupolev Tu-104
The Tupolev Tu-104 ( NATO reporting name: Camel) is a retired twinjet, medium-range, narrow-body turbojet-powered Soviet airliner. It was the second to enter regular service, behind the British de Havilland Comet, and was the only jetliner operating in the world from 1956 to 1958, when the British jetliner was grounded due to safety concerns. In 1957, Czechoslovak Airlines – ČSA, (now Czech Airlines) became the first airline in the world to fly a route exclusively with jet airliners, using the Tu-104A variant between Prague and Moscow. In civil service, the Tu-104 carried over 90 million passengers with Aeroflot (then the world's largest airline), and a lesser number with ČSA, while it also was operated by the Soviet Air Force. Its successors included the Tu-124, Tu-134, and Tu-154. Design and development At the beginning of the 1950s, the Soviet Union's Aeroflot airline needed a modern airliner with better capacity and performance than the piston-engined aircraf ...

De Havilland Comet
The de Havilland DH.106 Comet was the world's first commercial jet airliner. Developed and manufactured by de Havilland in the United Kingdom, the Comet 1 prototype first flew in 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wing roots, a pressurised cabin, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and was commercially promising at its debut in 1952. Within a year of entering airline service, problems started to emerge, three Comets being lost within twelve months in highly publicised accidents, after suffering catastrophic in-flight break-ups. Two of these were found to be caused by structural failure resulting from metal fatigue in the airframe, a phenomenon not fully understood at the time; the other was due to overstressing of the airframe during flight through severe weather. The Comet was withdrawn from service and extensively tested. Design and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messerschmitt Me 262
The Messerschmitt Me 262, nicknamed ''Schwalbe'' (German: "Swallow") in fighter versions, or ''Sturmvogel'' (German: "Procellariidae, Storm Bird") in fighter-bomber versions, is a fighter aircraft and fighter-bomber that was designed and produced by the German aircraft manufacturer Messerschmitt. It was the world's first operational Jet aircraft, jet-powered fighter aircraft. The initial design of what would become the Me 262 started in April 1939, prior to the start of the World War II, Second World War. While the aircraft performed its maiden flight on 18 April 1941, this was using Reciprocating engine, piston engine instead of jet propulsion; it was not until 18 July 1942 that the first jet-powered flight was performed. Progress on the project was delayed by problems with engines, metallurgy and top-level interference from figures such as Hermann Göring, head of the Luftwaffe, and Adolf Hitler. The latter advocated from the Me 262 to be operated as a Ground-attack aircraft, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
