HFB 314
The Hamburger Flugzeugbau HFB 314 was a postwar design project for a twin-turbojet medium-range transport. It was cancelled when the German government decided to fund only international collaborations. History In 1958 HFB proposed to the German Government two new transports, the HFB 209 turboprop and the HFB 314 short-range jet transport. The 314 would be a direct competitor to the French Sud Aviation Caravelle, then already under development. Although the German government was initially willing to negotiate over financing the projects, in the end they decided that the German aircraft industry should not develop its own designs but should instead collaborate with other countries. Finance was never made available and HFB could not progress without it. With the competing Boeing 727 and de Havilland DH.121 Trident both also advancing steadily, HFB abandoned the project in 1960.''Flight'', 18 November 1960, p. 805."Pas de Caravelle Allemande", ''Les Ailes'', No. 1,804, 16 Décember ...

Hamburger Flugzeugbau
''Hamburger Flugzeugbau'' (HFB) was an aircraft manufacturer, located primarily in the Finkenwerder quarter of Hamburg, Germany. Established in 1933 as an offshoot of Blohm & Voss shipbuilders, it later became an operating division within its parent company and was known as ''Abteilung Flugzeugbau der Schiffswerft Blohm & Voss'' from 1937 until it ceased operation at the end of World War II. In the postwar period it was revived as an independent company under its original name and subsequently joined several consortia before being merged to form Messerschmitt-Bölkow-Blohm (MBB). It participates in the present day Airbus and European aerospace programs. History In 1933 the Blohm & Voss shipbuilding company in Hamburg was suffering a financial crisis from lack of work. Its owners, brothers Rudolf and Walther Blohm, decided to diversify into aircraft manufacture, believing that there would soon be a market for all-metal, long-range flying boats, especially with the German state airli ...

Hamburger Flugzeugbau HFB 209
The Hamburger Flugzeugbau HFB 209 was a postwar design project for a twin-turboprop medium-range transport. It was cancelled when the German government decided to fund only international collaborations. History The HFB 209 was in effect a development of the CASA C-207 ''Azor''.

But government finance was not made available and HFB could not progress without it. Design The HFB 209 was a conventional low-wing monoplane intended as a 48-54 seat short-to-medium haul turboprop airliner. The fuselage, including the large underfloor freight compartment, was pressurised to The relatively large wing was o ... [...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 ...

Boeing 727
The Boeing 727 is an American narrow-body airliner that was developed and produced by Boeing Commercial Airplanes. After the heavy 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964. The only trijet aircraft to be produced by Boeing, the 727 is powered by Pratt & Whitney JT8D low-bypass turbofans below a T-tail, one on each side of the rear fuselage and a center one fed through an S-duct. It shares its six-abreast upper fuselage cross-section and cockpit with the 707. The long 727-100 typically carries 106 passengers in two classes over , or 129 in a single class. Launched in 1965, the stretched 727-200 flew in July 1967 and entered service with Northeast Airlines that Decem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Medway
The Rolls-Royce RB.141 Medway was a large low-bypass turbofan engine designed, manufactured and tested in prototype form by Rolls-Royce in the early-1960s. The project was cancelled due to changes in market requirements that also led to the development and production of the smaller but similar Rolls-Royce Spey, and the cancellation of the Armstrong Whitworth AW.681 military transport aircraft project. Design and development Designed by a team led by Alan Arnold Griffith, the RB.141 was originally designed to meet a new propulsion requirement for the de Havilland DH.121 airliner project which later became the Hawker Siddeley Trident. The engine was later named after the River Medway in line with Rolls-Royce company tradition for jet engines. The DH.121 itself was being designed to a requirement and specification from British European Airways issued in February 1958, and when this requirement was altered to that of a smaller aircraft, the Medway in its initial form was no longer n ...

General Electric CJ-805-23
The General Electric CJ805 is a jet engine which was developed by GE Aviation in the late 1950s. It was a civilian version of the J79 and differed only in detail. It was developed in two versions. The basic CJ805-3 was a turbojet and powered the Convair 880, while CJ805-23 (military designation TF35), a turbofan derivative, powered the Convair 990 airliners. Design and development Impetus Turbojet engines consist of a compressor at the front, a burner area, and then a turbine that powers the compressor. In order to reach worthwhile compression ratios, compressors consist of multiple "stages", each further compressing the air leaving the previous one. One common problem with early jet engines was the phenomenon of "surging" or compressor stall. Stalls could occur when the approaching airflow was not in-line with the aircraft inlet to the compressor or when the throttle was advanced too quickly. When engines had to be designed with pressure ratios greater than about 5, to meet d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney JT3D-3
The Pratt & Whitney JT3D is an early turbofan aircraft engine derived from the Pratt & Whitney JT3C. It was first run in 1958 and was first flown in 1959 under a B-45 Tornado test aircraft. Over 8,000 JT3Ds were produced between 1959 and 1985. Most JT3D engines still in service today are used on military aircraft, where the engine is referred to by its US military designation of TF33. Design and development Aware of the competition from the Rolls-Royce Conway turbofan, Pratt & Whitney decided to develop the JT3D turbofan from the JT3C turbojet for later deliveries of the Boeing 707 and the Douglas DC-8, then nearing entry into service. A 2-stage fan replaced the first 3 stages of the 9-stage JT3C LP compressor. On the LP turbine, the second stage was enlarged and a third stage added. Unlike GE with the CJ805-23, Pratt & Whitney had not undertaken any transonic fan research prior to designing the JT3D, so they were unable to incorporate a single stage unit into the specification ...
