D-27 aircraft turbofan engine
The D-27 engine is designed to power the An-70, An-70T, An-180, Be-42 airplanes manufactured at the Antonov Aviation Complex as well as other high-effi- ciency passenger and transport airplanes with improved take off and landing characteristics. The design of the D-27 engine ensures the following: • high efficiency within a wide range of power settings
• high reliability and trouble-free operation
• stability of perfomance parameters
•long service life
•low manufacture and maintenance manhours
• low level of harmful emissions
•acceptable noise level
