M45H-01

From Wikipedia, the free encyclopedia

Rolls-Royce/SNECMA M45H-01 was a medium bypass ratio turbofan produced specifically for the twin-engined VFW-614 aircraft.

The single-stage fan, together with a five-stage IP compressor, was driven by a three-stage LP turbine, whilst the seven-stage HP compressor was driven by a single-stage, air-cooled, HP turbine. An annular combustor and an unmixed exhaust, with a plug-type primary nozzle, were other design features.

The engine was developed at the time of the Rolls Royce bankruptcy and reportedly resulted in delays in developing the engine.
