Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (newtons, or N), hence thrust-specific. This figure is inversely proportional to specific impulse, which is the amount of thrust produced per unit fuel consumed. TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel n… WebJul 8, 2006 · CFM56-7B20 is rated at 91.6kN of Thrust. At 100% N1, it burns 0.91 KG of Fuel per second. This gives it a TSFC of 0.035752. This now means that the FFPH at cruise is around 2784.6kg per hour which when you multiply by two (for 2 engines) is equal to 5569.2.
