    • numericsData

      Numerical integration parameters

      • timeData

        Time integration settings

    • conditionsData

      Flight conditions and component states

    • ones_rowfunction

      Creates array of ones with specified size

• settings (Data) – Configuration settings for the simulation

• vehicle (Data) –

  Vehicle configuration data

  • networkslist

    List of propulsion system networks

    • fuel_lineslist

      Fuel distribution systems

    • propulsorslist

      Propulsion units

Returns:

• H2Ofloat

  Total H2O emissions [kg]

• NOxfloat

  Total NOx emissions [kg]

indexData

Emission indices

• CO2ndarray

  CO2 emission index [kg_CO2/kg_fuel]

• COndarray

  CO emission index [kg_CO/kg_fuel]
