T64
T64: Powering the medium-weight transport helicopter
The T64 is a turboshaft engine that was developed in collaboration with GE and Klöckner-Humboldt-Deutz (KHD) specially for medium-weight transport helicopters such as the Sikorsky CH-53. Production took place between 1968 and 1975. A total of 247 T64 engines were delivered.
Between 2003 and 2008, some technical enhancements were made to the T64 to equip it for missions in regions featuring challenging climate conditions and terrain. In 2014, the program to upgrade the T64-7 engines to the enhanced T64-100 standard was completed.
MTU’s involvement in the T64
MTU Aero Engines in Munich was primarily responsible for assembly and acceptance test runs for this helicopter engine. Today, MTU’s T64 activities focus on maintenance.
