General Electric T64

T64-GE-7 to drive a Sikorsky CH-53 G

The General Electric T64 is a single-shaft turboprop engine or a shaft turbine from the US manufacturer General Electric . The engine was developed for the US Navy Bureau of Weapons and has been used in helicopters and fixed-wing aircraft since the 1960s. The civil version is called the CT64.

history

The first flights with two T64-GE-4 were carried out on September 22, 1961 in a de Havilland DHC-4 Caribou . The T64-GE-10 was then chosen as the standard engine for the successor model de Havilland Buffalo developed from the Caribou . Four T64-GE-1 propelled the VTOL tilt-wing aircraft LTV / Ryan / Hiller XC-142A , the variants T64-GE-1, GE-7 and GE-100 drive the Sikorsky CH-53 versions.

Versions

T64-GE-1

Shaft turbine without gear (gear must be available on the cell side )

T64-GE-2

Wave turbine with reduction gear and helicopter engine governor

T64-GE-4

Turboprop with reduction gear below the center line, propeller brake

T64-GE-6

Wave turbine without gear

T64-GE-7

Shaft turbine without gearbox, manufactured under license by MTU for Sikorsky CH-53D and CH-53G, due to manufacturing tolerances not being fully utilized in German production, the maximum actual output was usually significantly higher than for turbines made in the USA

T64-GE-8 and GE-10

like GE-4 but reduction gear above the center line

T64-GE-12

T64-GE-100

like GE-7A with improved turbine

T64-GE-413

Wave turbine without gear

T64-GE-415

Shaft turbine without gearbox, improved turbine cooling

CT64-GE-820

Turboprop

T64-P4D or T64 / P4D
