AL-31F

AL-31F is an active afterburning low-bypass turbofan model in the canonical AL-31 family. UAC identifies two AL-31F engines on the Su-34 and rates the export Su-34E installation at 12,500 kgf (about 122.63 kN) afterburning thrust per engine with a -2% tolerance; Rostec identifies UEC-UMPO as the AL-31F producer. This record describes the engine model and does not make the Su-34 its sole installation.

    Note
    UAC identifies the Su-34 engine unit as two AL-31F engines and lists 12,500 kgf afterburning thrust per engine for the export Su-34E; this supports the model's normalized 122.63 kN afterburning rating and a bounded installation example.
