In these tests confirmed the performance of parts and components, including manufactured with the use of "critical technologies", "hollow" titanium rotor blade fan turbine blades of single crystal superalloys and intermetallic compounds, compressor blisks and others. Engine parameters correspond to the mathematical model, the report said, "Aviadvigatel."
Basic PD-14 with 14 tons of thrust is designed to fit a 180-seat modification of the prospective MS-21-300. Other options — throttled PD-14A with a thrust of 12.5 tons and forced PD-14M (draft 15.4 m) — will be used respectively for versions of MS-21-200 (150 pass.) And MS-21-400 (for 210 pass.).
