The PD-14 is a turbofan bypass two-shaft engine without exhaust mixer, with reverse and efficient noise suppression.
Compact common core-engine based PD engine family are Russian turbofan bypass two-shaft engines designed for short- and medium-range aircrafts and IGTs.
The main feature of the PD engine family is the use of compact common core-engine.
