Progress D-18T


The Progress D-18T is a triple-drive shaft, high-bypass turbofan, powering the Antonov An-124 Ruslan and An-225 large freighters.

Design and development

The engine was developed in the second half of the 1970s by the then Soviet Ivchenko-Progress design bureau. It is manufactured by the Motor Sich factory in Zaporizhia, Ukraine. It was the first engine in the USSR that could deliver more than 20,000 kgf of thrust.
The first start of a full-scale engine occurred on September 19, 1980, the An-124 maiden flight on December 24, 1982 and the engine passed official bench tests on December 19, 1985.
An upgraded 3M version was developed to reduce emissions and increase the life of the hot section to 14,000 h, and is introduced on An-124s of Antonov Airlines.
Currently 188 D-18T engines are in operation with a total flight time of over 1 million hours.
