FMA IA 36 Cóndor
The IA 36 ''Cóndor'' (English: Condor) was a projected Argentine jet propelled mid-range airliner, designed in the early 1950s by Kurt Tank for the “ Fábrica Militar de Aviones”. It was cancelled in 1958, with no prototypes built, but a full size wood mockup. Design and development Work on the IA 36 Cóndor project started in late 1951 by a team led by the German engineer Kurt Tank; as part of the project a 1:34 scale wind tunnel model was built, as well as a 1:1 scale wooden fuselage mock-up. The project was cancelled in 1958 by the government led by Pedro Eugenio Aramburu, which followed that of Juan Domingo Perón, deposed in 1955 by the now quite infamous Revolución Libertadora uprising. The projected aircraft would have been powered by five Rolls-Royce "Nene II" turbojets arranged in an annular configuration around the rear fuselage, as in Messerschmitt P.1110 and Heinkel He 211; however it was planned to replace those with lighter and more powerful engines in ...

Messerschmitt P
Messerschmitt AG () was a German share-ownership limited, aircraft manufacturing corporation named after its chief designer Willy Messerschmitt from mid-July 1938 onwards, and known primarily for its World War II fighter aircraft, in particular the Bf 109 and Me 262. The company survived in the post-war era, undergoing a number of mergers and changing its name from Messerschmitt to Messerschmitt-Bölkow-Blohm before being bought by Deutsche Aerospace (DASA, now part of Airbus) in 1989. History Background In February 1916, the south German engineering company MAN AG and several banks purchased the unprofitable aircraft builder Otto-Flugzeugwerke, starting a new company, ''Bayerische Flugzeugwerke AG'' (abbreviated ''B.F.W.''). The articles of association were drawn up on 19 and 20 February, and completed on 2 March 1916. Details of the company were recorded in the Commercial Register with an equity capital of RM 1,000,000 on 7 March 1916. 36% of the capital was provided ...

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 aircraft then ...

Avro Canada C102 Jetliner
The Avro Canada C102 Jetliner was a Canadian prototype medium-range turbojet-powered jet airliner built by Avro Canada in 1949. It was beaten to the air by only 13 days by the de Havilland Comet, thereby becoming the second jet airliner in the world. The name "Jetliner" was chosen as a shortening of the term "jet airliner", a term which is still in popular usage. The aircraft was considered suitable for busy routes along the US eastern seaboard and garnered intense interest, notably from Howard Hughes who even offered to start production under license. However continued delays in Avro Canada's all-weather interceptor project, the CF-100 Canuck, led to an order to stop working on the project in 1951, with the prototype Jetliner later cut up for scrap. Design and development Genesis In 1945 Trans-Canada Airlines (TCA) started exploring a number of aircraft developments under the direction of Jim Bain, at that time superintendent of engineering and maintenance.

Vickers V-1000
The Vickers-Armstrongs V-1000 was a proposed jet-powered cargo aircraft that was designed to meet a requirement issued by the British Ministry of Supply which sought a strategic transport for the Royal Air Force (RAF) to support its strategic bomber fleet, particularly the V-bombers. The design bears many similarities to the Vickers Valiant, one of the V-bombers, but also featured substantial changes. In addition to its military application, both the Ministry and Vickers also intended to use the same basic design as the VC7, a six-abreast trans-Atlantic jet airliner for British Overseas Airways Corporation (BOAC). In 1955, by which point the prototype was already largely complete, the Ministry of Supply decided to terminate the V-1000 project in mid-development. By that time, the design had garnered interest from airlines, and had led to re-designs being conducted by competing US manufacturers, influencing the design of the Boeing 707 and Douglas DC-8. The V-1000 is one of the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Efficiency (aerodynamics)
In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under given flight conditions. The L/D ratio for any given body will vary according to these flight conditions. For an aerofoil wing or powered aircraft, the L/D is specified when in straight and level flight. For a glider it determines the glide ratio, of distance travelled against loss of height. The term is calculated for any particular airspeed by measuring the lift generated, then dividing by the drag at that speed. These vary with speed, so the results are typically plotted on a 2-dimensional graph. In almost all cases the graph forms a U-shape, due to the two main components of drag. The L/D may be calculated using computational fluid dynamics or computer simulation. It is measured empirically by testing in a wind tunnel or in free flight te ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of gravity ...

FMA IAe 33 Pulqui II
The FMA IAe 33 Pulqui II (in the indigenous language Mapuche, ''Pulqúi'': Arrow)Crowder-Taraborrelli, Tomas F"Evita in Wonderland: Pulqui and the Workshop of Underdevelopment."''CineAction'', 22 June 2009. Retrieved: 26 April 2010. was a jet fighter aircraft designed by Kurt Tank in the late 1940s in Argentina, under the Perón government, and built by the Fábrica Militar de Aviones (FMA).Green and Pollinger 1955, p. 105. Embodying many of the design elements of the wartime Focke-Wulf Ta 183, an unrealized fighter project, the FMA envisioned the IAe 33 Pulqui II as a successor to the postwar Gloster Meteor F4 in service with the ''Fuerza Aérea Argentina''. The Pulqui II's development was comparatively problematic and lengthy, with two of the four prototypes being lost in fatal crashes. Despite one of the prototypes being successfully tested in combat during the 1955 ''Revolución Libertadora'', the political, economic and technical challenges faced by the project meant that ...

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 cons ... [...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 turbofan ...

BAC One-Eleven
The BAC One-Eleven (or BAC-111/BAC 1-11) was an early jet airliner produced by the British Aircraft Corporation (BAC). Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways order on 9 May 1961. The prototype conducted its maiden flight on 20 August 1963, and it was first delivered to its launch customer on 22 January 1965. The 119-seat, stretched 500 series was introduced in 1967. Total production amounted to 244 until 1982 in the United Kingdom and between 1982 and 1989 in Romania where nine Rombac One-Eleven were licence-built by Romaero. The short haul, narrowbody aircraft was powered by aft-mounted Rolls-Royce Spey low-bypass turbofans, a configuration similar to the earlier Sud Aviation Caravelle and later Douglas DC-9. It also competed with early Boeing 737 variants and was used by several US carriers, as well as multiple British, overseas and European airline ...

McDonnell Douglas DC-9
The McDonnell Douglas DC-9 is an American five-abreast single-aisle aircraft designed by the Douglas Aircraft Company. It was initially produced by the developer company as the Douglas DC-9 until August 1967 and then by McDonnell Douglas. After introducing its heavy DC-8 in 1959, Douglas approved the smaller, all-new DC-9 for shorter flights on April 8, 1963. The DC-9-10 first flew on February 25, 1965, and gained its type certificate on November 23, to enter service with Delta Air Lines on December 8. The aircraft has two rear-mounted Pratt & Whitney JT8D low-bypass turbofans under a T-tail for a cleaner wing aerodynamic, a two-person flight deck and built-in airstairs. The Series 10 are 104 ft (32 m) long for typically 90 coach seats. The Series 30, stretched by 15 ft (4.5 m) to seat 115 in economy, has a larger wing and more powerful engines for a higher maximum takeoff weight (MTOW); it first flew in August 1966 and entered service in February 1967.
