From Wikipedia

The Progress D-236 was an experimental aircraft engine, a hybrid between a turbofan and a turboprop known as a propfan. Also known as the Lotarev D-236T, the three-shaft geared engine was designed in the 1980s and 1990s to power proposed propfan aircraft such as the Tupolev Tu-334, Ilyushin Il-118, and Ilyushin Il-88. Based on the core of the Ukrainian Progress D-36 turbofan, the D-236 was the first Soviet propfan, and as of 2019 it is still one of only four different unshrouded, contra-rotating propfan engines to have flown in service or in flight testing.
