Estimation of nacelle and pylon geometry

class fastoad_cs25.models.geometry.geom_components.nacelle_pylons.compute_nacelle_pylons.Chord(x: float, y: float, length: float)

Bases: object

x: float

y: float

length: float

class fastoad_cs25.models.geometry.geom_components.nacelle_pylons.compute_nacelle_pylons.Nacelle(max_thrust: float)

Bases: object

Simple class for computing nacelle geometry

max_thrust: float

property diameter

Nacelle diameter in m.

property length

Nacelle length in m.

property wetted_area

Wetted area for one nacelle in m**2.

class fastoad_cs25.models.geometry.geom_components.nacelle_pylons.compute_nacelle_pylons.ComputeNacelleAndPylonsGeometry(**kwargs)

Bases: ExplicitComponent

Nacelle and pylon geometry estimation

Store some bound methods so we can detect runtime overrides.

initialize()

Perform any one-time initialization run at instantiation.

setup()

Declare inputs and outputs.

Available attributes:

name pathname comm options

setup_partials()

Declare partials.

This is meant to be overridden by component classes. All partials should be declared here since this is called after all size/shape information is known for all variables.

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)

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

An inherited component may choose to either override this function or to define a compute_primal function.

Parameters:

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

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

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

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