T64

The T64, a turboshaft engine with a maximum power of 3,229 kW (T64-100) for applications on medium-size transport helicopters, such as the Sikorsky CH-53, was built between 1968 and 1975 in cooperation with General Electric and Klöckner-Humboldt-Deutz (KHD). MTU’s role in this engine was chiefly assembly and acceptance test work at its Munich location. In all, 247 T64 engines were delivered. MTU now provides technical and logistic support for 273 active engines in Germany.

In 2003, the company began a comprehensive modification program to upgrade the T64-7 to the more powerful -100 standard.

The T64 engine has a single-shaft, 14-stage compressor, the inlet guide vanes and the first four stages of stator vanes of which are variable. The combustion chamber is annular. A two-stage turbine drives the compressor, and a two-stage free turbine drives the coaxial output shaft.
