Aviadvigatel PD-14

PD-14 (prej PS-14) je nova generacija ruskih visokoobtočnih turboventilatorskih reaktivnih letalskih motorjev. Razvija jih podjetje ОАО "Авиадвигатель", poganjal bo novo rusko dvomotorno letalo Irkut MS-21. Program PD-14 so objavili leta 2010, cena razvoja naj bi bila 35 milijard rubljev (US$ 1,1 milijard)[1][2]

Turbofan PD-14 naj bi kasneje razširili z motorjem PD-18R, ki bi imel reduktor, podobno kot ameriški PW1000G. Potisk PD-18R naj bi bil od 18000 kg do 20000 kg. Uporabljal bi se v težkih potniških in transportnih letalih, kot je Iljušin Il-96-300/400T. [3][4]

Aerodinamični ventilator

Nov motor naj bi imel za 10-15% manjšo porabo kot CFM International CFM56 in primerljivo z njegovim naslednikom CFM International LEAP. Izvedba motorja bo dvogredna. PD-14 se bo uporabljal tudi na letalih Tupoljev Tu-204 Iljušin Il-76, in UAC/HAL Il-214 večnamenskem letalu.[5]
