Thrust specific fuel consumption density Calculator

Thrust specific fuel consumption (TSFC) is a measure of the efficiency of an engine in converting fuel into thrust. It represents the amount of fuel consumed by an engine to produce a unit of thrust over a specific period of time.

Where:

  • is the thrust specific fuel consumption (units: mass flow of fuel per unit thrust, typically kg/N·s or lb/lbf·hr).
  • is the mass flow rate of fuel (units: kg/s or lb/hr).
  • is the thrust generated by the engine (units: N or lbf).
