Progress D-27

From Wikipedia, the free encyclopedia

Progress propfan on the Antonov An-70

The Progress D-27 is a propfan engine that the Ivchenko Progress company developed in the 1980s for commercial and military transport aircraft. Unlike the General Electric GE-36 UDF propfan, the D-27 has a fairly conventional layout, with a reduction gearbox linking the power turbine to the contra-rotating propfan blades, which are located at the front of the engine (i.e. tractor configuration). Early work stalled because aviation fuel became cheap in real terms and of concerns about excessive cabin noise.

Currently, there is no mass-produced aircraft that is powered by the D-27. The sole aircraft that was supposed to use the D-27, the Antonov An-70 military transport, has not been ordered by the any nation or company.
