T64

The T64 engine was developed by General Electric to power helicopters and propeller aircraft.

In 1964 the engine achieved a fuel consumption corresponding to that of a piston engine in the same power category. FAA type certification for vertical and horizontal flight was secured in 1965. MTU Aero Engines built the T64-MTU-7 version under licence from General Electric for the CH-53G helicopters of the German armed forces. Between 1972 and 1975, MTU Aero Engines produced, assembled and delivered a total output of 267 engines. MTU now provides technical and logistic support for 273ea. active engines in Germany.

Late in 1976 and the beginning of 1977, MTU Aero Engines tested a growth version of the T64-7 developing 3,850 kW (5,230 HP) in two 300-hour runs. This amounts to over 30% more power from the growth version. Since 2004 MTU Aero Engines is upgrading the T64-7 engines to T64-100 growth version.

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.
