Design and development

The engine was developed for the Yak-42, An-72 and An-74 aircraft and was very advanced when it was first introduced in the 1970s. The engine was designed by Vladimir Lotarev. The first test runs began in 1971, first flight tests followed in 1974, serial production began in 1977.
The engine has a single-stage compressor with 29 titanium blades and a Kevlar outer shell, which is driven by a three-stage turbine. The six-stage low pressure compressor with titanium blades is driven by a single-stage non-cooled low pressure turbine. The seven-stage high-pressure compressor with steel blades is driven by a steel bladed high-pressure turbine.
Series 4A engines for An-74TK-300 have a built-in reverse thrust device.
