The Progress D-18T (also known as the Lotarev D-18T) is a high-bypass turbofan engine rated at approximately 51,500 lbf (229 kN) thrust, primarily used to power the large cargo aircraft Antonov An-124 Ruslan and Antonov An-225 Mriya.

Design and development

Conceived during the latter half of the 1970s by the Soviet-era design bureau Ivchenko-Progress, this engine is produced by the Motor Sich plant located in Zaporizhzhia, Ukraine. It holds the distinction of being the first engine in the USSR capable of generating thrust exceeding 20,000 kgf (roughly 196 kN or 44,000 lbf). The initial full-scale engine test run took place on September 19, 1980. Subsequently, the An-124 completed its inaugural flight on December 24, 1982, and the engine successfully passed official bench testing on December 19, 1985.

A refined variant known as the 3M model was created to lower emissions and extend the hot section's service life to 14,000 hours; this version has been implemented on An-124 aircraft operated by Antonov Airlines. At present, there are 188 D-18T engines active worldwide, collectively accumulating over one million flight hours.

Incidents

Template:Seealso In March 2020, Ukrainian regulators mandated a one-time inspection of all D-18T intermediate pressure compressor disks after an incident involving an uncontained engine failure. These inspections were required to be completed within a six-month timeframe. On November 13, 2020, a Volga-Dnepr Airlines Antonov An-124 experienced an uncontained failure in its inboard left (number 2) D-18T engine.
