Thrust specific fuel consumption Solution

STEP 0: Pre-Calculation Summary

Formula Used

Thrust-Specific Fuel Consumption = Fuel to Air Ratio/Specific Thrust
TSFC = f_a/I_sp
This formula uses 3 Variables

Variables Used

Thrust-Specific Fuel Consumption - (Measured in Kilogram per Second per Newton) - Thrust-Specific Fuel Consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output.
Fuel to Air Ratio - Fuel to Air Ratio is the ratio of mass flow rate of fuel to the mass flow rate of air.
Specific Thrust - (Measured in Meter per Second) - Specific Thrust is the thrust produced per unit mass in per unit time.

STEP 1: Convert Input(s) to Base Unit

Fuel to Air Ratio: 0.0006 --> No Conversion Required
Specific Thrust: 137.02 Meter per Second --> 137.02 Meter per Second No Conversion Required
