Total Energy At Nozzle Exit For a Rolls Royce Gnome Engine Calculator

The Rolls-Royce Gnome is a turboshaft engine commonly used in various helicopters. In the context of a turboshaft engine, the term “nozzle exit” typically refers to the point where the exhaust gases exit the power turbine section.

The total energy ($E$) at the nozzle exit can be expressed as:

where,

• E is the Total Energy, i.e sum of kinetic and potential energy
• $h$ is the static enthalpy at the nozzle exit,
• $V$ is the velocity of the exhaust gases relative to the reference frame of the exhaust gases
