Around 1970-1980, “Motoren-und-Turbo Union” became the main German manufacturer of aero-engines, building the engines for the Panavia “Tornado”, the RB-199.

-From BMW they received the small engines of the 6000 series.

“MTU/BMW 6012”

“MTU/BMW 6022”

-Constituted 50% between MAN (that had already merged with BMW Flugmotorenbau GmbH in 1960) and Daimler-Benz that merged in 1968, initially called MAN-Entwicklung and on January 1, 1970 it became MTU with two bases: MTU in Munich and MTU in Friedrichshafen.

-Precisely the MTU in Friedrichshafen was previously Maybach-Mercedes Benz Motorenbau, with a part of Daimler-Benz.

-Later Daimler joins Chrysler and is called Daimler-Chrysler.

-Going through other types of vicissitudes. But as we will see, the company's policy is to collaborate with many brands at the same time in the production of parts for their engines and to provide service and maintenance to all products. Cooperating in the offered materials, both military and civil.

-It takes part in the manufacture of engines from other companies with different percentages.

-For example, it intervened in the 1,000 shp MTM-385 turboshaft, a product made with Turbomeca.

-The joint venture was established in Paris as MTU/Turbomeca SARL.

“MTM-385”

-This engine was planned for the German-French helicopter MBB/Aero-spatiale (today Eurocopter-EADS), PAH2 / HAC.

“MTM-385R”

-The MTM-385 is a derivative of the original MTM-380. Currently the MTR-390 engines are in production. (see MTR).

-Historically it was involved in the J-79 engines that were used on the German Phantom F4s.

-They were the J-79-MTU-J1K, the RR Tyne from the Transall C-160, the Larzac 04 in collaboration with Turbomeca for the Alpha Jet. Or the Allison 250 used in various German helicopters such as the Bölkow B-107.

-The T-64 turboshaft was made for Sikorsky CH-53G helicopters.

-Its participation in the RB-199 engine of the Tornado and in the EJ-200 of the Eurofighter Typhoon is important.

-More recently they are involved in the development of the TP-400-D6 for Airbus' future European military transport aircraft, the A400M.

-The ones seen so far are the engines for military use, and the intervention in civilian engine programs is also very important. One of these engines is the veteran V2500 used on the Airbus A-319, A-320 and A-321 as well as on some Boeing MD-90 aircraft.

“V-2500”

-They are still participating in the JT8D, a two-shaft turbofan that delivers 90 to 100 kN of thrust for the MD-80 family.

“JT8D”

-The PW300 and PW-500, both from P&W Canada, also have a part of MTU intervention. They are intended for business aviation. The former is seen on the Learjet 60 and the latter on the Cessna Citation Bravo.

“PW-300 from 18 to 30 kN”

"PW-500 from 13 to 20 kN"

-Another veteran engine in which MTU has part of its realization is the CF6 with a thrust between 180 and 320 kN depending on the model. They are intended for Airbus, Boeing and MD.

“CF6”

-The PW-2000 with two shafts was planned for the Boeing 757. MTU is involved in the PW-4000 Growth for the Boeing 777 and the PW-6000 for the Airbus A-318. They are heads of series.

“PW-6000”

-MTU also intervenes in the one that will power some models of the large Airbus A-380 aircraft. It is the GP-7000 in its different series.

“GP-7000”

-Doing a small review of interventions in engines of other companies, we have the following:

-The Allison-RR 250 in collaboration with Rolls-Royce, current owner of Allison.

-The MTR-390 with RR and Turbomeca.

-The RB-199 with RR and Italian Avio.

-For the J-79 they intervened with GE. The same for the T-64.

-With RR and Snecma they worked together on the Tyne and the TP-400D6. The latter with the Spanish ITP in addition.

-With the Larzac for the Alpha-Jet MTU collaborates with Snecma, Turbomeca and RR-Deutschland.

-El motor EJ-200 del Eurofighter se hace conjuntamente con RR, Avio e ITP.

-The Eurofighter EJ-200 engine is made jointly with RR, Avio and ITP.

-The international cooperation of the V-25900 is carried out jointly with Pratt & Whitney, Rolls-Royce and the Japanese JAEC.

-The CF6 with the GE, Snecma, Volvo and Avio.

-The JT8D-200 has been made with Pratt & Whitney, Volvo and Mitsubishi.

-The two little PW-300 and -500 with the Canadian P&W.

-The PW-800, turbofan with an advanced technology gear.

“PW-800”

-The PW-2000 with the PW itself, Volvo and Avio.

-The PW-4000 Growth, with P&W, Avio, Mitsubishi, Kawasaki and Samsung.

-The PW-6000 with P&W and Mitsubishi.

-Now we come to the great GP-7000, which in its different series is going to reach -or exceed- 100,000 lbf of thrust. Here MTU intervenes with P&W, GE and Snecma (Safran).

-Below a cutaway of the PW-800 in which we can see the fan reducer as the most significant device.

“MTU/PW-800”

-They also study new technologies to reduce noise, emissions and consumption, and to be friendly with nature.

-For example, the Clean Air Engine programs (Claire I, II and III) technology.

-To reduce consumption, there is the IRA or Intercooled Recuperative Aero Engine program.

"IRA heat recovery system"

-Finally to end with the MTU chapter, the company logo.

“MTU logo”

-At the beginning of the 21st century, Daimler-Chrysler has sold the MTU subsidiary to the American financial group KKR.

From Appendix 6: By 1980, MTU had 13 percent of the Prat and Whitney JT10D-232 engine that gave 32,000 lbf of thrust.

"The MTU-PW JT10D-232 engine"

-At the beginning of the MTM series, they made a scale-model of the MTM-300, the head of series that would give rise to the MTM-390, etc.

“MTM-300 scale model”

From Appendix 7: We have a cutaway of the MTU, model 6012 to be able to check the simplicity of the hot part, with an annular chamber and fuel supply by spraying in the Turbomeca way.
