Thermal Efficiency of a Lockheed F-104 StarFighter Engine Calculator

The Lockheed F-104 Starfighter is an American single-engine, supersonic air superiority fighter which was extensively deployed as a fighter-bomber during the Cold War. Created as a day fighter by Lockheed as one of the “Century Series” of fighter aircraft for the United States Air Force (USAF), it was developed into an all-weather multirole aircraft in the early 1960s and produced by several other nations, seeing widespread service outside the United States.

The thermal efficiency is expressed mathematically as:

where:

  •  is the thermal efficiency,
  •  is the thrust produced by the engine,
  •  is the jet velocity,
  • f is the mass flow rate of fuel,
  •  is the specific enthalpy of the fuel.
