Thrust-specific fuel consumption(TSFC) is the fuel efficiencyof an enginedesign with respect to thrustoutput. HP = TE x Fuel flow (PPH) x 19,000 (BTU per #) / 2545 (BTU per HP per hour) HP = TE x Fuel flow (PPH) x 7.466. It is thus thrust-specific, meaning that the fuel consumption is divided by the thrust. Divide the fuel volumed consumed by the distance traveled and multiply it by 100. The off-design code calculates engine performances (i.e., thrust and thrust-specific-fuel-consumption) at various flight conditions and throttle settings. Specific fuel consumption (SFC) is the conventional fuel efficiency metric for jet engines. Nomenclature A Flow area a Sound speed C Constants cp Specific heat at constant pressure F Uninstalled thrust f Fuel/air ratio gc Newton's constant g0 Acceleration of gravity h Altitude To calculate the fuel consumption in tons, use this formula: fuel consumption(ton/s) = Thrust/10 SI.
