Thermal Efficiency of a Aerojet Rocketdyne Engine Calculator

Aerojet Rocketdyne is a subsidiary of American defense company L3Harris Technologies that manufactures rocket, hypersonic, and electric propulsive systems for space, defense, civil and commercial applications.

The thermal efficiency is expressed mathematically as:

where:

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