The MTU Aero Engines AG , based in Munich, is a publicly traded company whose business the production and maintenance of engines for civil and military aviation is.


BMW Flugmotorenbau GmbH was founded in 1934 and spun off directly from BMW AG in order to be less subject to publication requirements. This happened on the one hand under pressure from the Reich Aviation Ministry , which wanted to conceal the armament efforts of the Air Force and the associated need for BMW engines in the balance sheets; on the other hand, the interests of the company management were also taken into account, which wanted to minimize the risks of an operation exclusively tailored to rearmament by the outsourcing. In 1936, BMW built a pure aero-engine plant in Allach near Munich, which is now the headquarters of MTU Aero Engines. In 1940 the company was expanded and the large-scale production of BMW 801 aircraft engines began , which were used, for example, in the FW 190 fighter or the Do 217 bomber . During the Second World War, forced laborers had to work in production on a large scale , so that by 1943 the German core workforce was in the minority with a share of 29%. In February 1943, the Dachau-Allach satellite camp was built directly adjacent to the BMW premises . The concentration camp prisoners worked in production or built bunkers on the factory premises to protect the production facilities from air raids, for which primarily Jewish inmates were assigned.

In April 1945 American troops occupied the plant and used it as a repair shop for army vehicles and artillery. This saved the factory from being completely dismantled. After the lifting of the production ban for engines, BMW returned to the development and production of aircraft engines with BMW Triebwerkbau GmbH in 1957.

The MTU brand was established in the late 1960s, initially with two locations in Friedrichshafen and Munich. Activities were later concentrated, in Friedrichshafen on piston engines and the integration of stationary gas turbines , in Munich on aviation propulsion systems .

The abbreviation "MTU" originally stands for "Motoren- und Turbinen-Union". MTU Munich and MTU Friedrichshafen used to be under this name , the latter being a daughter of the Munich mother for a long time (and now forming the core of Rolls-Royce Power Systems ).

In 1985 what was then Daimler-Benz AG acquired the remaining 50% stake from MAN and made MTU part of DASA . This was in line with Edzard Reuter's corporate goal at the time to position the group as broadly as possible and not concentrate on a single core business. Because MTU Aero Engines is an engine manufacturer and not an aircraft or space manufacturer, when DASA merged with other pure aircraft and space manufacturers to form EADS in 2000 , it was not integrated into the new European aerospace company. MTU therefore remained a subsidiary of the DaimlerChrysler group.

Edzard Reuter's successor, Jürgen Schrempp , reorganized the group as a pure automobile manufacturer, which is why there was no longer any space for the aerospace division of MTU in the DaimlerChrysler group. Therefore, DaimlerChrysler sold that part of the original MTU in 2003 as MTU Aero Engines to the US private equity -Investorengruppe KKR which MTU on 6 June 2005 to the stock market brought. The share was included in the MDAX effective September 19, 2005 . In January 2006, KKR sold its shares completely. As a result, 100% of the shares are now in free float .

In April 2013, the company's Supervisory Board appointed Reiner Winkler, the previous CFO , as CEO of MTU Aero Engines AG on January 1, 2014. Egon Behle was no longer available for a contract extension.

After a share price increase of 750 percent over the course of ten years, MTU was promoted from the MDAX as a new member to the league of the 30 most valuable listed companies, the DAX , with effect from September 23, 2019 .

Company structure and business areas

Group headquarters of MTU Aero Engines in Munich- Allach

MTU Aero Engines develops, manufactures, sells and supports civil and military aircraft engines in numerous thrust and power classes as well as stationary industrial gas turbines and marine gas turbines. In addition to high-pressure compressors and low-pressure turbines, it develops and manufactures other engine components such as turbine center frames, turbine outlet housings and brush seals.

Today MTU Aero Engines is a partner in almost every modern engine in civil aviation. In the military sector, too, there is hardly a manned aircraft at national level in which the company is not involved in the drive. MTU has close ties with all major manufacturers such as Pratt & Whitney , General Electric , Rolls-Royce , Safran Aircraft Engines and GKN Aerospace through corresponding investments or subsidiaries (MTU Aero Engines North America) .

With the founding of the first maintenance company, MTU Maintenance Hannover, MTU entered the maintenance of commercial engines on a large scale in 1979. The company is active in the maintenance market with its maintenance group and local locations in Langenhagen ( Hanover ), Ludwigsfelde ( Berlin ), Vancouver ( Canada ) and Zhuhai ( People's Republic of China ).

The Hanover location is the heart of the maintenance group and repairs and overhauls medium-sized and large commercial engines. These include the GE CF6-50 and CF6-80C2 actuators , the General Electric GE90 , the PW2000 from Pratt & Whitney , the CFM56-7 from General Electric / Snecma, and the IAE V2500.

MTU Maintenance Berlin-Brandenburg, based in Ludwigsfelde, specializes in aerospace engines in the lower to medium thrust and power range as well as industrial gas turbines. The site serves Pratt & Whitney Canada's engines - PT6A, PW200 , PW300 and PW500 - as well as GE's CF34 family. The Group's competence center for industrial gas turbines is also located here.

The company has a total of 14 locations worldwide. The commercial engine business currently accounts for around 54 percent of sales. Civilian maintenance accounts for around 35 percent and the military business for 11 percent.

Since 2009, the company has opened the company's own MTU Museum Edi Strack to the public on a few days a year at its Munich location. This is the case every quarter on a Sunday from 1 p.m. to 6 p.m. One exception is the Long Night of the Munich Museums .

In 2002 the company received the German Business Innovation Prize . In 2013, MTU Aero Engines was again able to win the German Business Innovation Award in the large company category. This time for the development of the high-speed low-pressure turbine of the Pratt & Whitney PW1000G engine.

In the engine industry, mergers for the production of different turbines in different constellations are common in order to distribute the development and financial burden on several shoulders. Even larger companies could face difficulties if an engine does not find the desired popularity on the market. In addition to the complexity of the engines, the main reason for the high development costs is the comparatively long time span from the start of development to final delivery. Also, the individual engine types are no longer derived to a certain extent from previous military engines, which was often the case, especially during the Cold War .

MTU Aero Engines is involved in various consortia that jointly develop and ultimately manufacture engines. In the civil sector, for example, this is the case at International Aero Engines , the manufacturer of the V2500 engine . It is used in the McDonnell Douglas MD-90 and the Airbus A320 family . The 4,000th V2500 engine was delivered in August 2009. The engines used on the aircraft of the A320 family come in thrust versions from 110 kN to 150 kN (versions A1 and A5 / A5Select). On the McDonnell Douglas MD-90, the V2500-D5 derivative was the exclusive drive until the aircraft ceased production in 2000.

A similarly structured consortium, the Engine Alliance , is supplying the GP7000, one of the two available propulsion systems for the Airbus A380. Around half of the 200 wide-body aircraft of this type ordered to date are currently powered by this engine. The engine is essentially based on the GE90 and the Pratt & Whitney PW4000 . The Engine Alliance is a joint venture between General Electric and Pratt & Whitney , but is supplemented by a number of additional partners. For MTU Aero Engines, it is the engine with the highest program participation in the civil sector - it is 22.5 percent.

Civil projects

In addition, the company is involved in numerous other engines as a partner:

MTU turbine engine at ILA 2018
  • Pratt & Whitney PW4000 : Manufacturer is the US aerospace group Pratt & Whitney. The engine is - depending on the expansion stage - located in the thrust range between 84,600 and 98,000 pounds of thrust. This makes it one of the most powerful engines ever built. It was the first engine that had a 180-minute ETOPS approval from the start. It is used on the Boeing 777 , among other things , but also on various Airbus models such as the A330 or A310 . MTU Aero Engines developed the turbine outlet casing and the low-pressure turbine. The company is also involved in the production of this. Overall, MTU's share in this engine is 12.5 percent.
  • Pratt & Whitney PW6000 : This engine has been developed in cooperation with Pratt & Whitney since 1998 and is a drive variant for the Airbus A318. For the first time in its history, MTU produced the complete high-pressure compressor and the complete low-pressure turbine on a civil engine. The final assembly of the now no longer manufactured PW6000 was carried out at the MTU location in Langenhagen .
  • Pratt & Whitney PW2000 : The PW2000 is one of the few engines that are used in both civil ( Boeing 757 ) and military ( Boeing C-17 ) areas. MTU has been developing the low-pressure turbine and the turbine outlet casing since 1979. The company is also involved in the production of the low-pressure turbine, so that MTU's program share amounts to a total of 21.2 percent.
  • Pratt & Whitney PW1000G : This engine is equipped with a geared turbofan so that the fan and the low-pressure turbine can each run at optimal speeds. The A320neo is offered with a corresponding variant of this engine. Depending on the application, MTU has a program share of up to 18 percent on the PW1000G and is responsible for the development and manufacture of the so-called high-speed low-pressure turbine and the first four high-pressure compressor stages. Nickel blisks are also manufactured for other components of the high-pressure compressor.
  • Pratt & Whitney Canada PW800 : A twin-shaft, turbofan engine from the PurePower® family for medium-sized business aircraft, thrust class 10,000 to 20,000 pounds. MTU has a 15 percent stake in this engine. The participation includes the development and manufacture of high pressure compressors and low pressure turbines.
  • Pratt & Whitney Canada PW500 and Pratt & Whitney Canada PW300 : Both engines are twin-shaft turbofan engines for medium-sized business jets. MTU has a 25 percent stake in the PW305, PW306 and PW307 as well as the PW530 and PW545 models. The participation includes the development and manufacture of the low-pressure turbine, housing and mixer.
  • General Electric GEnx : The GEnx is the next generation engine family from the US manufacturer. It is based on the General Electric GE90 and is the successor to the General Electric CF6, the best-selling type of engine for wide-body aircraft. MTU holds a 6.5 percent stake in the GEnx program and is responsible for the development, manufacture and assembly of the turbine center frame.
  • General Electric GE9X : The GE9X is the successor engine of the General Electric GE90 and exclusive drive of the Boeing 777X. MTU develops and manufactures the turbine center frame, which corresponds to a program share of four percent. The market entry is planned for 2020 (as of February 2016). As of February 2019, there were 2,013 firm orders for the 777X.
