Ivchenko Progress D-36
The Ivchenko Progress D-36 (also Lotarjow D-36 ) is a three-shaft turbo- fan engine with a high bypass ratio from the Zaporizhia engine plant Ivchenko Progress .
The development of this engine intended for the Jak-42 , An-72 and An-74 (very advanced for the time and Soviet conditions) began at the beginning of the 1970s under the direction of Vladimir Lotarjow . The first test runs began in 1971, the first flight attempts followed in 1974. Series production began in 1977.
The engine has a single-stage fan with 29 titanium blades and an outer shell made of aramid ("Kevlar"), which is driven by a three-stage turbine . The six-stage low - pressure compressor with titanium blades is driven by a single-stage, uncooled low-pressure turbine. The seven-stage high-pressure compressor with steel blades is driven by a single-stage film and internally cooled high pressure turbine.
The Series 4A engine for the An-74TK-300 is equipped with a thrust reverser as standard.
