Tu-334
The Tupolev Tu-334 () was a Russian short-to-medium range airliner project that was developed to replace the aging Tupolev Tu-134 and Yak-42s in service around the world. The airframe was based on a shortened Tu-204 fuselage and a scaled-down version of that aircraft's wing. Unlike the Tu-204, however, the Tu-334 has a T-tail and engines mounted on the sides of the rear fuselage instead of under the wings. With the nationalisation of the Russian aircraft companies in 2009 to form United Aircraft Corporation it was decided not to continue with the programme. Development The Tupolev Design Bureau introduced the Tu-334 in early 1989 as an eventual propfan-powered airliner to potentially enter service for Aeroflot in 1995. However, it would have an interim turbofan-powered version that would begin airline service around 1991–1992. Consuming about 20 percent less fuel than the best Soviet turbofan, the propfan engine would be a then-unnamed geared powerplant from the Lotarev ...

Progress D-436
The Progress D-436 is a triple-spool high-bypass turbofan engine developed by the Ukrainian company Ivchenko-Progress during the Soviet era, and manufactured by Motor Sich in Ukraine. It was initially developed to meet the requirements for late versions of the Yakovlev Yak-42 and the Antonov An-72 in the 1980s. The engine first ran in 1985 and was subsequently certified in 1987. Several variants have been developed and are currently in service with a variety of aircraft. Design and development The D-436 engine was developed as a follow on to the Lotarev D-36. The engine took several of its design features from that engine and another Progress engine, the Progress D-18. The D-436 incorporated an updated, higher RPM fan, a lower emissions combustor, and new compressor sections. Several variants of the engine incorporate a FADEC. The Motor-Sich plant in Zaporozhie, where the assembly line for D-436 engines was located, was destroyed by Russian forces in late May 2022 follo ...

Progress D-27
The Progress D-27 is a three-shaft propfan engine developed by Ivchenko Progress, and manufactured by Motor Sich in Ukraine. The gas generator was designed using experience from the Lotarev D-36 turbofan. The D-27 engine was designed to power more-efficient passenger aircraft such as the abandoned Yakovlev Yak-46 project, and it was chosen for the Antonov An-70 military transport aircraft. As of 2019, the D-27 is the only contra-rotating propfan engine to enter service. Design and development The engine was launched in 1985 by the Ivchenko-Progress Design Bureau for commercial and military transport aircraft. It was designed to meet the expected growth in demand for new aero engines for civil and military applications. It has a take-off rating of for the Antonov An-70. Gunston lists ratings between for the engine. In 1990, the D-27 engine was proposed for the 150-162 seat Yakovlev Yak-46 airliner. This twin-engined derivative of the three-engine Yakovlev Yak-42 would mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tupolev Tu-204
The Tupolev Tu-204 () is a twin-engined medium- range narrow-body jet airliner capable of carrying 210 passengers, designed by Tupolev and produced by Aviastar-SP and Kazan Aircraft Production Association. First introduced in 1995, it was intended to be broadly equivalent to the Boeing 757, with slightly lower range and payload, and had competitive performance and fuel efficiency in its class. It was developed for Aeroflot as a replacement for the medium-range Tupolev Tu-154 trijet in the 1990s. The latest version, with significant upgrades and improvements, is the narrow-body Tu-204SM, which made its maiden flight on 29 December 2010. In April 2022, United Aircraft Corporation (UAC) announced plans to assemble 70 Tu-214s by 2030. However, in early 2024, Aeroflot expressed intention to transfer its order for fleets exclusively to next-generation MC-21 jets. The rejection of the Tupolev has various reasons, including no two-member cockpit, and also the evacuation ramps and ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propfan
A propfan, also called an open rotor engine, open fan engine is an aircraft engine combining features of turbofans and turboprops. It uses advanced, curved propeller blades without a ducted fan, duct. Propfans aim to combine the speed capability of turbofans with the fuel efficiency of turboprops, especially at high subsonic speeds. It is sometimes called a "ultra-high-bypass (UHB) turbofan". Definition In the 1970s, Hamilton Standard described its propfan as "a small diameter, highly loaded multiple bladed variable pitch propulsor having swept blades with thin advanced airfoil sections, integrated with a nacelle contoured to retard the airflow through the blades thereby reducing compressibility losses and designed to operate with a turbine engine and using a single stage reduction gear resulting in high performance". In 1982, the weekly aviation magazine Flight International defined the propfan as a propeller with 8–10 highly swept blades that cruised at a speed of , a ...

Narrow-body Aircraft
A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than , allowing at least seven-abreast seating and often more travel classes. Market Historically, beginning in the late 1960s and continuing through the 1990s, twin engine narrow-body aircraft, such as the Boeing 737 Classic, McDonnell-Douglas MD-80 and Airbus A320 were primarily employed in short to medium-haul markets requiring neither the range nor the passenger-carrying capacity of that period's wide-body aircraft. The re-engined Boeing 737 MAX and Airbus A320neo jets offer 500 miles more range, allowing them to operate the 3,000 miles transatlantic flights between the eastern U.S. and Western Europe, previously dominated by wide-body aircraft.

Cebu Pacific
Cebu Air, Inc. (), operating as Cebu Pacific (stylized in lowercase), is a Philippine low-cost airline based in Pasay, Metro Manila. Founded in 1988, the airline was the first low-cost carrier in Asia and is also the largest airline in the Philippines by fleet size. It offers scheduled flights to both domestic and international destinations. The airline operates flights from five bases in Cebu, Clark, Davao, Iloilo, and its largest base in Manila. With its low-cost business model and extensive destination network, Cebu Pacific became the Philippines' largest airline based on number of passengers flown on domestic and international routes in 2010, overtaking rival Philippine Airlines (PAL). According to Civil Aeronautics Board data, Cebu Pacific flew a total of 2.45 million passengers in the first quarter of 2010, nearly 110,000 more than PAL, which carried 2.34 million systemwide during the same period. The airline has often been criticized for its frequent flight delays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geared
A gear or gearwheel is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machined on the part, or separate pegs inserted into it. In the latter case, the gear is usually called a cogwheel. A cog may be one of those pegsDefinition of "cog" in the ''Oxford Learner's Dictionary'' online. Accessed on 2024-07-29.Definition of "cog" in the ''Merriam-Webster Dictionary'' online.

General Electric GE36
The General Electric GE36 was an experimental aircraft engine, a hybrid between a turbofan and a turboprop, known as an unducted fan (UDF) or propfan. The GE36 was developed by GE Aviation, General Electric Aircraft Engines, with its CFM International equal partner Snecma taking a 35 percent share of development. Development was cancelled in 1989. Development General Electric (GE) started performing studies and component test work on the concept that would become the UDF in 1981, based on the initial results of early National Aeronautics and Space Administration (NASA) propfan technology studies that the aerospace agency first released to engine makers in 1980. GE then followed up with full-scale development testing of the GE36 starting in 1982. NASA gave GE a $20.4 million contract in February 1984 to study the concept after the company showed the agency its work in December 1983, as NASA's own propfan research efforts were advancing at a slower pace and were dependent on additi ...
