Turboprop
A turboprop is a Gas turbine, gas turbine engine that drives an aircraft Propeller (aeronautics), propeller. A turboprop consists of an intake, reduction drive, reduction gearbox, gas compressor, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the Fuel mixture, fuel-air mixture then Combustion, combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xian Y-7
The Xi'an Y-7 () is a twin turboprop transport/passenger aircraft built in China. It is based on the Soviet-designed Antonov An-24 series. Development China imported the Antonov An-24 from early in its production run and also negotiated licenses for production of the aircraft and its engines. In 1966, Xi'an aircraft factory started the project of local production of An-24. The first Chinese-assembled An-24T had its maiden flight on 25 December 1970. Production was launched in 1977 at the Xi'an aircraft factory but progress was slow due to the deleterious effects of the Cultural Revolution, with a pre-production aircraft displayed to the public at Nanyuan air base, near Beijing, on 17 April 1982. The WJ-5A1 turboprop engine was chosen as the Y-7's power source. The first production aircraft was not flown until February 1984, illustrating the slow progress (eighteen years from license to production). The Chinese aircraft equated to the An-24RV, having a full complement of windo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric
General Electric Company (GE) was an American Multinational corporation, multinational Conglomerate (company), conglomerate founded in 1892, incorporated in the New York (state), state of New York and headquartered in Boston.

Harbin SH-5
The Harbin SH-5 (, where "水轰" is short for ) is a Chinese maritime patrol amphibious aircraft intended for a wide range of duties, including aerial firefighting, anti-submarine warfare (ASW) and air-sea rescue (ASR). One prototype and six production aircraft have been built. Design and development Research to build a seaplane capable of replacing Beriev Be-6s in service was initiated by the PLANAF in 1968, with designers reassigned from "Objective 3/17", a supersonic canard-wing fighter project. The first prototype flew in 1976; further units were delivered between 1986 and 1990. Variants ;SH-5B Firefighter :One SH-5 was rebuilt for firefighting duties. :However, by a Chinese source, there were total of 7 SH-5 were produced: 3 SH-5X Prototype, 3 Maritime patrol aircraft, and 1 SH-B Firefighter. Operators ; * People's Liberation Army Naval Air Force received 4 aircraft in 1986. All are operated by the People's Liberation Army Navy North Sea Fleet from an aircraft base near ...
