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.
The Boeing 787 Dreamliner is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. After dropping its unconventional Sonic Cruiser project, Boeing announced the conventional 7E7 on January 29, 2003, which focused largely on efficiency. The program was launched on April 26, 2004, with an order for 50 aircraft from All Nippon Airways (ANA), targeting a 2008 introduction. On July 8, 2007, a prototype 787 without major operating systems was rolled out; subsequently the aircraft experienced multiple delays, until its maiden flight on December 15, 2009. Type certification was received in August 2011, and the first 787-8 was delivered in September 2011 before entering commercial service on October 26, 2011, with ANA.
The CFM International CFM56 series is a Franco-American family of high-bypass turbofan aircraft engines made by CFM International (CFMI), with a thrust range of 18,500 to 34,000 lbf. CFMI is a 50–50 joint-owned company of Safran Aircraft Engines of France, and GE Aerospace (GE) of the United States. GE produces the high-pressure compressor, combustor, and high-pressure turbine, Safran manufactures the fan, gearbox, exhaust and the low-pressure turbine, and some components are made by Avio of Italy and Honeywell from the US. Both companies have their own final assembly line, GE in Evendale, Ohio, and Safran in Villaroche, France. The engine initially had extremely slow sales but has gone on to become the most used turbofan aircraft engine in the world.
The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Dr. Benjamin Franklin Goodrich, the company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001. Originally a rubber manufacturing company known for automobile tires, the company diversified its manufacturing businesses throughout the twentieth century and sold off its tire business in 1986 to focus on its other businesses, such as aerospace and chemical manufacturing. The BFGoodrich brand name continues to be used by Michelin, who acquired the tire manufacturing business in 1988. Following the acquisition by United Technologies in 2012, Goodrich became a part of UTC Aerospace Systems.
CFM International is a Franco-American aircraft engine manufacturer. The company is a joint venture between GE Aerospace and Safran Aircraft Engines and is headquartered in Cincinnati, Ohio.

WheelTug is a company known for its in-wheel electric taxiing system for airplanes. They are headquartered in the Isle of Man and have manufacturing facilities in Baltimore, Maryland.
An Electric Green Taxiing System (EGTS) is an electric taxiing system which allows aircraft to taxi and pushback without requiring the use of aircraft engines or a pushback tractor, and is designed to reduce fuel volumes used by aircraft and reduce greenhouse gas emissions during ground operations. EGTS technology enables aircraft to avoid using their main engines during taxiing and instead taxi autonomously under their own electrical power, using the Auxiliary Power Unit (APU) generator. The system is designed for single-aisle aircraft, such as the Airbus A320 and the Boeing 737.
Jean-Paul Béchat was a French engineer. He was the CEO of Snecma then Safran until 2007.
