Thermal Efficiency of a RB.203 Engine Calculator

The RB.203 was a private venture engine built on the core of the Rolls-Royce Turbomeca Adour turbofan used in the SEPECAT Jaguar and the later Hawker Siddeley Hawk.

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.
