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.

The MTR390 development phase having successfully been completed, a 332-engine procurement contract was awarded in 2000. First export customers are Australia and Spain. For Spain, an uprated version of the engine, the MTR390 Enhanced, is being developed.

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