because their cores are based on the AL-31F's, whereas the AL-41F utilizes an entirely different approach.

testbed. An 18–tonne (177 kN, 40,000 lbf) class engine, the AL-41F used a variable bypass architecture to facilitate the aircraft in supercruise, or fly at speeds of Mach 1.5 without afterburner. It had the ambitious goal of increasing the turbine inlet temperature by 250 °C over its

With the abandonment of the MFI, the
