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 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.
Safran Helicopter Engines, previously known as Turbomeca, is a French manufacturer of low- and medium-power gas turbine turboshaft engines for helicopters. The company also produces gas turbine engines for aircraft and missiles, as well as turbines for land, industrial and marine applications.
Safran Aircraft Engines, previously Snecma or Snecma Moteurs, is a French aerospace engine manufacturer headquartered in Courcouronnes and a subsidiary of Safran. It designs, manufactures and maintains engines for commercial and military aircraft as well as rocket engines for launch vehicles and satellites.
Safran Landing Systems, formerly Messier-Bugatti-Dowty, is a French company involved in the design, development, manufacture and customer support of all types of aircraft landing gear, wheels and brakes and a wholly owned subsidiary of Safran SA. It is the world's largest manufacturer of aircraft landing gear.
SAGEM was a French company involved in defense electronics, consumer electronics, and communication systems.
Zodiac Aerospace was a French aerospace group founded in 1896 that supplied systems and equipment for aircraft. In October 2018, it was acquired by French aerospace and defense company Safran. At the time of acquisition, it was one of the oldest aerospace groups known to exist.
Avio S.p.A. is an Italian company operating in the aerospace sector with its head office in Colleferro near Rome, Italy. Founded in 1908, it is present in Italy and abroad with different commercial offices and 10 production sites. Avio operates in:
Vulcain is a family of European first stage rocket engines for Ariane 5 and the future Ariane 6. Its development began in 1988 and the first flight was completed in 1996. The updated version of the engine, Vulcain 2, was first successfully flown in 2005. Both members of the family use liquid oxygen/liquid hydrogen cryogenic fuel. The new version under development for Ariane 6 will be called Vulcain 2.1.
The HM7B was a European cryogenic upper stage rocket engine used on the vehicles in the Ariane rocket family. It will be replaced by Vinci, which will act as the new upper stage engine on Ariane 6. Nearly 300 engines have been produced to date.
The CFM International LEAP is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aerospace and French Safran Aircraft Engines. It is the successor of the CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft.
Airbus SE is a European multinational aerospace corporation. The company’s primary business is the design and manufacturing of commercial aircraft but it also has separate defence and space and helicopter divisions. Since 2019, Airbus has been the world's largest manufacturer of airliners as well as the leading helicopter manufacturer.
Airbus Defence and Space is the division of Airbus SE responsible for the development and manufacturing of the corporation's defence and space products and providing related services. The division was formed in January 2014 during the corporate restructuring of European Aeronautic Defence and Space (EADS) into Airbus SE, and comprises the former Airbus Military, Astrium, and Cassidian divisions. It is said to be the world's second largest space company.
Technodinamika, JSC Russian: АО Технодинамика ("Technodynamics") was established in 2009 in order to promote development, production and export of high-technology products for civil aviation markets. Originally established as Aviation Equipment Holding, it was given its current name in 2015.
ArianeGroup is an aerospace company based in France. A joint venture between Airbus and Safran, the company was founded in 2015 and is headquartered in Issy-les-Moulineaux. It consists of three core groups: aerospace, defence and security. ArianeGroup is developing its next-generation two-stage Ariane 6 launch vehicle, intended to succeed the Ariane 5 rocket, which has had more than 110 launches. The new vehicle will be offered in two variants that will be capable of carrying between 10,350 and 21,650 kilograms. The first launch of Ariane 6 is expected to occur in 2024.
The Musée aéronautique et spatial Safran is a French private aviation museum located in Melun, Seine-et-Marne. Established in May 1989 the museum contains a large collection of historic and modern aircraft engines. These engines have been produced by various French engine manufacturers such as Gnome et Rhône and Snecma which are now part of the present day Safran company. The latter is the creator and manager of the museum.
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.
A hybrid electric aircraft is an aircraft with a hybrid electric powertrain. As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032.
