append_internal_combustion_engine_conditions#

append_internal_combustion_engine_conditions(propulsor, segment, energy_conditions, noise_conditions)[source]#

Initializes internal combustion engine operating conditions for a mission segment.

Parameters:
  • propulsor (RCAIDE.Library.Components.Propulsors.Internal_Combustion_Engine) –

    Internal combustion engine propulsor component with the following attributes:
    • tagstr

      Identifier for the engine

    • itemsdict

      Dictionary of subcomponents

  • segment (RCAIDE.Framework.Mission.Segments.Segment) –

    Mission segment with the following attributes:
    • stateData
      Segment state
      • ones_rowfunction

        Function to create array of ones with specified length

  • energy_conditions (RCAIDE.Framework.Mission.Common.Conditions) – Energy conditions container where engine conditions will be stored

  • noise_conditions (RCAIDE.Framework.Mission.Common.Conditions) – Noise conditions container where engine noise conditions will be stored

Returns:

Results are stored in energy_conditions.propulsors[propulsor.tag] and segment.state.conditions.noise[propulsor.tag]

Return type:

None

Notes

This function initializes the necessary data structures for storing internal combustion engine operating conditions during a mission segment. It creates zero-filled arrays for various performance parameters and recursively calls the append_operating_conditions method for each subcomponent of the engine.

The function initializes the following parameters in energy_conditions:
  • throttle

  • commanded_thrust_vector_angle

  • thrust

  • power

  • moment

  • fuel_flow_rate

  • inputs and outputs containers

It also creates a noise conditions container for the engine.

Major Assumptions
  • All arrays are initialized with zeros

  • Each component has an append_operating_conditions method
