Total Energy At Nozzle Inlet For a Propeller Driven Engine Calculator

Propeller-driven engines, on the other hand, are a type of aircraft propulsion system that relies on the rotation of a propeller to generate thrust. For propeller-driven engines, the emphasis is on the aerodynamics of the propeller and the mechanical power it extracts from the engine to accelerate the air.

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

where,

• E is the Total Energy, i.e sum of kinetic and potential energy
• $h$ is the Static Enthalpy at nozzle Inlet,
• $V$ is the velocity of the incoming air relative to the reference frame of the engine
