A turboshaft engine featuring a free power turbine, the MTR390 powers the Tiger support helicopter co-developed by France and Germany. The production engines for the 2C (basic) version were delivered between 2002 and mid-2010—242 units for the Franco-German Tiger program and 51 for the Australian ARH program. In 2011, in collaboration with ITP Aero in Spain, an enhanced version of the engine (the MTR390-E) was developed that delivers 14 percent more power.
 

MTU’s involvement in the MTR390

MTU developed the MTR390 in collaboration with Safran Helicopter Engines and Rolls-Royce. MTU’s workshare in the E version includes the combustor and high-pressure turbine as well as controller hardware complete with operating system. In addition, the assembly line for all MTR390-E production engines is located at MTU Aero Engines in Munich.
