The Progress D-27 is a three-shaft propfan engine developed by Ivchenko Progress. It is not clear whether the D-27 engine's core is related to or derived from the D-36 turbofan which is a three-shaft turbofan. The D-27 engine was developed specifically to power more efficient passenger aircraft such as the abandoned Yak-46 project and it was chosen to power the An-70 military transport aircraft. The D-27 is expected to be a base platform for future engine derivatives.

Design and development

The engine was developed by the Ivchenko-Progress Design Bureau for commercial and military transport aircraft. It was designed to meet the expected growth in demand for aeronautical products which include the development of a number of new aero engines of civil and military application.

D-27 is regarded as a pacesetter and perhaps a first in the world for production turbopropfan engines. It is rated at a maximum power of 14000shp. Currently, the D-27 is undergoing official flight testing as installed in medium-range military airlifter, the An-70.

In developing the D-27 engine, Ivchenko-Progress also came up with a proposal for several derivatives based on the core of the D-27 engine. For instance the following derivatives have been proposed for different purposes and at different times:

(These are proposed drive low-noise wide-span fans via a reduction gear)

The D-27’s two-shaft gas turbine engine 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 are no mass-produced aircraft that are powered by the D-27.
