fastga.models.weight.mass_breakdown.b_propulsion.b1_2_oil_weight module

Python module for oil weight calculation, part of the propulsion system mass computation.

class fastga.models.weight.mass_breakdown.b_propulsion.b1_2_oil_weight.ComputeOilWeight(**kwargs)[source]

Bases: openmdao.core.explicitcomponent.ExplicitComponent

Weight estimation for motor oil.

Based on a statistical analysis. See [WHM17].

Store some bound methods so we can detect runtime overrides.

initialize()[source]

Perform any one-time initialization run at instantiation.

setup()[source]

Declare inputs and outputs.

Available attributes:

name pathname comm options

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)[source]

Compute outputs given inputs. The model is assumed to be in an unscaled state.

Parameters

  • inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

  • outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

  • discrete_inputs (dict or None) – If not None, dict containing discrete input values.

  • discrete_outputs (dict or None) – If not None, dict containing discrete output values.
