specific fuel consumption
- The quantity of fuel consumed (by weight) to produce one unit of power in one unit of time. In piston engines, the SFC is equal to the mass ratio of fuel/shaft horsepower. In gas turbine engines, the SFC is equal to the mass ratio of fuel/thrust. It is best when its value is minimum. The value of the SFC decreases with height and in colder temperature conditions.Effect of altitude on engine performance at constant airspeed.SFC versus RPM and temperature.
