The Continental CAE T51 was a small
turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the ex ...
engine produced by
Continental Aviation and Engineering (CAE) under license from
Turbomeca. A development of the
Artouste, it was followed by three additional turboshaft engines, the T72, the T65, and the T67.
However, none of these engines, including the T51, entered full production. CAE abandoned turboshaft development in 1967 after the XT67 lost to the
Pratt & Whitney Canada PT6T (T400) to power the Bell
UH-1N Twin Huey.
