D-136
The Ivchenko-Progress D-136 engine on display at the 2009 MAKS Air Show.
Type Turboshaft
National origin Soviet Union
Manufacturer Ivchenko-Progress / Motor Sich
Major applications Mil Mi-26
Developed from Lotarev D-36
Developed into Progress D-236

The Lotarev D-136 is a turboshaft engine from the ZMKB Progress Design Bureau. The engine powers the Mil Mi-26 "Halo" helicopter. Development of the engine had begun in about 1972.[1]: 76 . The D-136 first flew on a production Mi-26 helicopter in 1980.[1]: 79 

Design

The core of the engine is identical to the Lotarev D-36 turbofan from which the D-136 is derived.[2]
