 The Su @-@ 35 is powered by a pair of izdeliye ( Product ) 117S ( AL @-@ 41F1S ) turbofan engines . Developed jointly by Sukhoi , NPO Saturn and UMPO , the engine is a heavily upgraded AL @-@ 31F variant , and draws on the design of the fifth @-@ generation PAK FA 's Saturn 117 ( AL @-@ 41F1 ) engines . Its thrust output is estimated at 142 kN ( 31 @,@ 900 lbf ) , 20 kN ( 4 @,@ 500 lbf ) more than the Su @-@ 27M 's AL @-@ 31F . It has a service life of 4 @,@ 000 hours , compared to the AL @-@ 31F 's 1 @,@ 500 ; the two engines feature thrust @-@ vectoring capability . Each thrust vectoring ( TVC ) nozzle has its rotational axis canted at an angle , similar to the configuration on the Su @-@ 30MKI . The thrust vectoring nozzles operate in one plane for pitch , but the canting allows the aircraft to produce both roll and yaw by vectoring each engine nozzle differently . A similar thrust vectoring system is also implemented on the PAK FA .
