Thermal Efficiency of a Lockheed F-94 Starfire Engine Calculator

The Lockheed F-94 Starfire was a first-generation jet powered all-weather day/night interceptor aircraft designed and produced by Lockheed Corporation. It was the first operational United States Air Force (USAF) fighter equipped with an afterburner as well as being the first jet-powered all-weather fighter to enter combat during the Korean War.

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.
