Engine Model

The Engine Model has been included in the turbofan repository, and the constraints within it are detailed in Martin York’s Master’s thesis.

Currently both of the Engine and Aircraft models take FlightState as their arguments. To further aid in integrating the Engine model with new or existing configurations, here is a non-exhaustive list of ways that the engine can and should be integrated into a complete aircraft model.

• Integrate the engine weight into the dry weight of the aircraft.
• Link engine thrust to aircraft drag, climb rate, and fuel burn.
• Link engine sizing variables to the landing gear model.
• Link engine fan area to vertical tail engine out sizing constraint.
• Link engine fan and LPC diameter to the nacelle drag constraints.
• Link engine weight to nacelle weight.
• Link mach numbers (M2) in the engine model to the flight segment Mach number.
• Add engine to aircraft CG model.
