The D-30KP engine features a two-shaft configuration with exhaust mixing from both ducts. The two-rotor compressor has a three-stage first rotor and an eleven-stage second rotor. The engine has a cannular combustion chamber. The high-pressure turbine has two stages, and the low-pressure turbine has four stages. The nozzle, common for both ducts, has a blade mixer and a mixing chamber. This is Russia’s first production engine to feature cooled rotor blades of the first turbine stage and a clamshell reverser, which does not affect the engine performance at the forward thrust mode.

Variants

The D-30KP Series 2 engine provides the design take-off thrust at the ambient air temperature of +30oC. The engine is installed on the Il-76TD, Il-76MD, Il-76TP, Il-78, and A-50 aircraft. The D-30KPV version (without reverser) is developed for the A-40 aircraft
