The Progress D-436 is a triple-spool high-bypass turbofan engine developed by the Ukrainian company Ivchenko-Progress during the Soviet era, and manufactured by Motor Sich in Ukraine. It was initially developed to meet the requirements for late versions of the Yakovlev Yak-42 and the Antonov An-72 in the 1980s. The engine first ran in 1985 and was subsequently certified in 1987. Several variants have been developed and are currently in service with a variety of aircraft.
The D-436 engine was developed as a follow on to the Lotarev D-36. The engine took several of its design features from that engine and another Progress engine, the Progress D-18. The D-436 incorporated an updated, higher RPM fan, a lower emissions combustor, and new compressor sections. Several variants of the engine incorporate a FADEC.
The Motor-Sich plant in Zaporizhzhia, where the assembly line for D-436 engines was located, was destroyed by Russian forces in late May 2022 following the 2022 Russian invasion of Ukraine.
