The Progress D-27 is a three-shaft propfan engine derived from the D-36 turbofan.
Contents |
The engine was developed by the Ivchenko-Progress Design Bureau for commercial and military transport aircraft.
The D-27’s two-shaft gas generator is made up of an axial low-pressure compressor, a mixed-flow high-pressure compressor, an annular combustion chamber, a single-stage high-pressure turbine, and a single-stage low-pressure turbine. The SV-27 contra-rotating propfan, provided by SPE Aerosila, is driven by a four-stage turbine via a shaft connected to a planetary reduction gear housing a thrust meter and mechanism to prevent rotor acceleration.
Currently, there is no mass-produced aircraft that is powered by the D-27.
