Rolls-Royce RB.203 Trent
The Rolls-Royce RB.203 Trent was a British medium-bypass turbofan engine of around 10,000lb thrust designed for production in the late 1960s, bearing no relation to the earlier Rolls-Royce RB.50 Trent turboprop or the later high-bypass Rolls-Royce Trent turbofan. Design and development The RB.203 was a private venture engine built on the core of the Rolls-Royce Turbomeca Adour turbofan used in the SEPECAT Jaguar and the later Hawker Siddeley Hawk. The first three-spool engine, it was intended as a civilian replacement for the earlier Rolls-Royce Spey. The RB.203 Trent was a member of an Advanced Technology Engine family of engines with thrusts covering a range from the RB.203 of just under to the RB.207 of up to . The engine designs were launched at the SBAC Farnborough Airshow in September 1966. The Advanced Technology Engine RB.203 embraced the new scalable technologies such as the three-spool architecture, a high pressure annular combustor, the extensive use of composi ...

WikiProject Aircraft
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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

1960s Turbofan Engines
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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.

Rolls-Royce/SNECMA M45H
The Rolls-Royce/SNECMA M45H is an Anglo-French medium bypass ratio turbofan produced specifically for the twin-engined VFW-Fokker 614 aircraft in the early 1970s. The design was started as a collaborative effort between Bristol Siddeley and SNECMA. Design and development The VFW 614 was designed to operate over short sectors with up to a dozen flights a day. The engines were optimized for 30-minute sectors at a cruise altitude of 21,000 feet at Mach 0.65. Only a few minutes would be spent at the cruise rating and most of the flight would be at the higher climb rating or at a descent setting. The engine had a low turbine entry temperature and comparatively low rotational speed. The engine was designed to be uprated without drastic redesign. Three options were water injection (+10% thrust), improved HP turbine (+10% thrust), addition of a zero-stage to the LP compressor (+25% thrust). The M45H-01 was to have a thrust-specific fuel consumption (TSFC) of . The engine was devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power-egg
A power-egg is a complete "unitized" modular engine installation, consisting of engine and all ancillary equipment, which can be swapped between suitably designed equipment, with standardised quick-changing attachment points and connectors. In aircraft so designed the power-egg is typically removed before mean time to failure is reached and a fresh one installed, the removed engine then being sent for maintenance. Spare power-eggs may be stored in sealed containers, to be opened when needed. The power-egg or ''Kraftei'' format was used in some German Second World War era aircraft, particularly for twin or multi-engined airframe designs. It existed in two differing formats – the initial ''Motoranlage'' format which used some specialized added components depending on what airframe it was meant for use on, and the ''Triebwerksanlage'' format, a more complete unitization format usually including exhaust and oil cooling systems. Applications Germany Inline and radial engines wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nacelle
A nacelle ( ) is a "streamlined body, sized according to what it contains", such as an engine, fuel, or equipment on an aircraft. When attached by a pylon entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft cockpit may also be housed in a nacelle, rather than in a conventional fuselage. Etymology Like many aviation terms, the word comes from French, in this case from a word for a small boat. Development The development of the Arado Ar 234, merging the four nacelles into two The Arado Ar 234 was one of the first operational jet aircraft with engines mounted in nacelles. During its development, the four jet engines were merged from having four distinct nacelles, all of which contained their own landing gear wheel, to two nacelles with two engi ...

Fairchild 228
The Fairchild 228 was a regional jet developed for the United States market by Fairchild Hiller using Fokker F28 sub-assemblies. Design and development In 1967 Fairchild-Hiller sought to develop their own regional jet, the FH-327. Fairchild elected to leverage their relationship with Fokker aircraft in building F.27 aircraft, with a similar arrangement. The plan was to purchase sub-assemblies for the then new F.28 regional jet and assemble them in America into a shortened configuration aircraft with different engines. The Fairchild 228 was to be a 50-passenger twin-engine turbofan regional aircraft. The engines were mounted on the rear of the fuselage, with a swept T-tail arrangement. The wings were equipped with triple-slotted flaps for short-field operations. A new thrust Rolls-Royce RB.203 Trent turbofan was selected to power the aircraft. Fairchild estimated orders of 260-460 aircraft for the US market and 600-800 Internationally. The first sub-assemblies were shipped t ...

Accessory Drive
The accessory drive is a gearbox that forms part of a gas turbine engine. Although not part of the engine's core, it drives the accessories, fuel pumps, etc., that are otherwise essential for the operation of the engine or the aircraft on which it is mounted. Accessory drives on large engines handle between 400–500 hp. Components Power for the accessory drive is taken from the central shaft linking the turbine and compressor sections of the engine. This requires an internal gearbox that couples the drive to a radial driveshaft or ''towershaft'' that drives an external gearbox. Internal gearbox The design of the internal gearbox is complicated by the heat and small space available in which to connect the driveshaft. It is usually placed between the compressor outlet and the combustor. In turboprops or designs with centrifugal compressors, it may be placed ahead of the compressor. For two-shaft designs, an accessory drive will be taken from the high-pressure sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
