An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz, to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems.
An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, or spacecraft. Aerospace is a high technology industry.
Bombardier Aviation is a division of Bombardier Inc. It is headquartered in Dorval, Quebec, Canada. Its most popular aircraft included the Dash 8 Series 400, CRJ100/200/440, and CRJ700/900/1000 lines of regional airliners, and the newer CSeries. It also manufactured the Bombardier 415 amphibious water-bomber, and currently makes the Global Express and the Challenger lines of business jets.
The Airbus A319 is a member of the Airbus A320 family of short- to medium-range, narrow-body, commercial passenger twin-engine jet airliners manufactured by Airbus. The A319 carries 124 to 156 passengers and has a maximum range of 3,700 nmi. Final assembly of the aircraft takes place in Hamburg, Germany and Tianjin, China.
The Airbus A320 family is a series of narrow-body airliners developed and produced by Airbus. The A320 was launched in March 1984, first flew on 22 February 1987, and was introduced in April 1988 by Air France. The first member of the family was followed by the longer A321, the shorter A319, and the even shorter A318 . Final assembly takes place in Toulouse in France; Hamburg in Germany; Tianjin in China since 2009; and Mobile, Alabama in the United States since April 2016.
The Airbus A318 is the smallest and least numerous variant airliner of the Airbus A320 family. The A318 carries 107 to 132 passengers and has a maximum range of 5,750 kilometres. Final assembly of the aircraft took place in Hamburg, Germany. It is intended primarily for short-range service.
The Airbus A220 is a family of five-abreast narrow-body airliners by Airbus Canada Limited Partnership (ACLP). It was originally developed by Bombardier and had two years in service as the Bombardier CSeries. The program was launched on 13 July 2008, the smaller A220-100 made its maiden flight on 16 September 2013, was awarded an initial type certificate by Transport Canada on 18 December 2015, and entered service on 15 July 2016 with launch operator Swiss Global Air Lines. The longer A220-300 first flew on 27 February 2015, received an initial type certificate on 11 July 2016, and entered service with airBaltic on 14 December 2016.
The Irkut MC-21 is a single-aisle airliner, developed in Russia by the Yakovlev Design Bureau and produced by its parent Irkut, a branch of the United Aircraft Corporation (UAC), itself a 92%-owned subsidiary of Russia's state-owned aviation giant Rostec.
A constant speed drive (CSD) also known as a constant speed generator, is a type of transmission that takes an input shaft rotating at a wide range of speeds, delivering this power to an output shaft that rotates at a constant speed, despite the varying input. They are used to drive mechanisms, typically electrical generators, that require a constant input speed.
A regional jet (RJ) is a jet-powered regional airliner with fewer than 100 seats. The first one was the Sud-Aviation Caravelle in 1959, followed by the widespread Yakovlev Yak-40, Fokker F-28, and BAe 146. The 1990s saw the emergence of the most widespread Canadair Regional Jet and its Embraer Regional Jet counterpart, then the larger Embraer E-Jet and multiple competing projects. In the US, they are limited in size by scope clauses.
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 4 metres (13 ft) in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than 5 metres (16 ft), allowing at least seven-abreast seating and often more travel classes.
Integrated modular avionics (IMA) are real-time computer network airborne systems. This network consists of a number of computing modules capable of supporting numerous applications of differing criticality levels.
The Pratt & Whitney PW1000G, also called the GTF, is a high-bypass geared turbofan engine family produced by Pratt & Whitney. After many demonstrators, the program was launched with the PW1200G on the Mitsubishi SpaceJet in March 2008, first flight tested in July 2008. The first variant to be certified was the PW1500G for the Airbus A220 in February 2013. The program cost is estimated at $10 billion.
The Commercial Aircraft Corporation of China, Ltd. is a Chinese state-owned aerospace manufacturer established on 11 May 2008 in Shanghai. The headquarters are in Pudong, Shanghai. The company has a registered capital of RMB 19 billion. The corporation is a designer and constructor of large passenger aircraft with capacities of over 150 passengers.
Honeywell Aerospace is a manufacturer of aircraft engines and avionics, as well as a producer of auxiliary power units (APUs) and other aviation products. Headquartered in Phoenix, Arizona, it is a division of the Honeywell International conglomerate. It generates approximately $10 billion in annual revenue from a 50/50 mix of commercial and defense contracts.
The Comac C919 is a narrow-body airliner developed by Chinese aircraft manufacturer Comac. The development program was launched in 2008. Production began in December 2011, with the first prototype rolled out on 2 November 2015 and having its maiden flight on 5 May 2017. On 29 September 2022, the C919 received its CAAC type certificate. The first production airframe was delivered to China Eastern Airlines on 9 December 2022 and was put into commercial passenger service on 28 May 2023.
The Comac C929 is a planned long-range 250-to-320-seat wide-body twinjet airliner family being developed by Chinese Comac, to challenge the Airbus and Boeing duopoly. Construction of the first prototype began by September 2021.
Liebherr-Aerospace is the aerospace equipment manufacturing division of Liebherr. The company is an original equipment manufacturer (OEM); its low visibility in the minds of end consumers can be attributed to the OEM nature of all its operations.
