MTR390

Developed in cooperation with Turbomeca and Rolls-Royce, the MTR390 is a turboshaft engine featuring a free power turbine. It is used on the French-German escort and anti-tank Tiger helicopter.

Production engines of the MTR390-2C version (basic version) were delivered from 2002 to mid-2010 (of which 242 for the Franco-German tiger program and 51 for the Australian ARH program). In total, the order book stands at 445 engines, including exports. The “Enhanced” version, which has 14 percent more power, has been developed together with Spain's ITP since late 2004. Production deliveries have already started, with Spain being the launch customer for the MTR390E. By amending parts of their contracts for the MTR390-2C version France and Germany will increase the order backlog for the MTR390E to 147 engines.

MTU's stake in the engine includes the core engine with its combustor and gas generator turbine, and a number of accessories.
