Functions

compute_payload_power_draw(payload, bus, ...)

Computes the power draw of a payload component on an electrical bus.
compute_payload_power_draw(payload, bus, conditions)[source]#

Computes the power draw of a payload component on an electrical bus.

Parameters:

  • payload (RCAIDE.Library.Components.Systems.Payload) –

    Payload component with the following attributes:
    • tagstr

      Identifier for the payload

    • power_drawfloat

      Power required by the payload [W]

  • bus (RCAIDE.Library.Components.Systems.Electrical_Bus) –

    Electrical bus component with the following attributes:
    • tagstr

      Identifier for the electrical bus

    • power_split_ratiofloat

      Ratio of power allocation to this bus

    • efficiencyfloat

      Efficiency of the bus [0-1]

  • conditions (RCAIDE.Framework.Mission.Common.Conditions) –

    Flight conditions with:
    • energydict
      Energy conditions indexed by component tag
      • [bus.tag]Data
        Bus-specific conditions
        • [payload.tag]Data

          Payload-specific conditions - power : numpy.ndarray

          Power draw of the payload [W]

        • power_drawnumpy.ndarray

          Total power draw on the bus [W]

Return type:

None

Notes

This function calculates the power draw of a payload component on an electrical bus and updates the total power draw on the bus. The power draw is adjusted by the bus power split ratio and efficiency.

Major Assumptions

  • Constant payload power draw

  • Constant bus efficiency

  • Power draw is independent of flight conditions
