fastga_he.models.propulsion.components.tanks.gaseous_hydrogen_tank.components.sizing_tank_drag module

class fastga_he.models.propulsion.components.tanks.gaseous_hydrogen_tank.components.sizing_tank_drag.SizingGaseousHydrogenTankDrag(**kwargs)

Bases: ExplicitComponent

Class that computes the contribution to profile drag of the hydrogen tanks according to the position given in the options. For now this will be 0.0 regardless of the option except when under the wing or under the aircraft belly.

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

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.

compute_partials(inputs, partials, discrete_inputs=None)

Compute sub-jacobian parts. The model is assumed to be in an unscaled state.

Parameters:

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

• partials (Jacobian) – Sub-jac components written to partials[output_name, input_name]..

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