The 131-9D initially was designed for the McDonnell Douglas MD-90 series; the 131-9B became standard equipment on Boeing 737NG; the 131-9A on the Airbus A320 family. [4] The 131-9C has entered service aboard the Airbus A220 (formerly Bombardier C-Series). The 131 Series uses a two-stage axial turbine and a single generator which starts the APU. [5]
The Airbus A320neo family is an incremental development of the A320 family of narrow-body airliners produced by Airbus.The A320neo family (neo being Greek for "new", as well as an acronym for "new engine option") is based on the enhanced variant of the previous generation A319, A320, and A321, which was then retrospectively renamed the A320ceo family (ceo being an acronym for "current engine ...
The Airbus A320 is a low-wing airliner with twin turbofans and a conventional tail. The Airbus A320 family are narrow-body (single-aisle) aircraft with a retractable tricycle landing gear and powered by two wing pylon-mounted turbofan engines. After the oil price rises of the 1970s, Airbus needed to minimise the trip fuel costs of the A320.
The 4,000th V2500 was delivered in August 2009 to the Brazilian flag carrier TAM and installed on the 4,000th Airbus A320 family aircraft, an A319. [9] In early 2012, the 5,000th V2500 engine was delivered to SilkAir, and IAE achieved 100 million flying hours. [7]
The first flight test on one of its intended production airframes, the Bombardier CSeries (Airbus A220), was on September 16, 2013. [19] The A320 engine, the PW1100G, had made its first static engine test run on November 1, 2012, [20] and was first tested on the 747SP on May 15, 2013. [21]
The first German jet engines built during the Second World War used a mechanical APU starting system designed by the German engineer Norbert Riedel.It consisted of a 10 horsepower (7.5 kW) two-stroke flat engine, which for the Junkers Jumo 004 design was hidden in the engine nose cone, essentially functioning as a pioneering example of an auxiliary power unit for starting a jet engine.
Ram air turbine on Airbus A320. The Airbus A380 has the largest RAT in the world at 1.63 metres (64 in) in diameter, but around 80 centimetres (31 in) is more common. A typical large RAT on a commercial aircraft can be capable of producing 5 to 70 kW, depending on the generator. Smaller, low airspeed models may generate as little as 400 watts.
On aircraft such as the Airbus A310, Airbus A320 family, Airbus A320neo, Airbus A330, [5] Airbus A330neo, Airbus A340, [6] Boeing 737 Next Generation, 747, 757, 767 and 777, an integrated drive generator (IDG) is used. [7] This unit is simply a CSD and an oil cooled generator inside the same case. [8]
