fastga_he.models.propulsion.components.propulsor.propeller.components.sizing_propeller_ref_cl module

class fastga_he.models.propulsion.components.propulsor.propeller.components.sizing_propeller_ref_cl.SizingPropellerReferenceCl(**kwargs)

Bases: ExplicitComponent

For the computation of the slipstream effects, the “clean” lift coefficient of the section behind the propeller will be required. As is done elsewhere is FAST-OAD_CS23 we will assume that the “shape” of the lift distribution won’t change so to obtain the said lift coefficient we will simply interpolate the Cl=f(y) curve.

As a first step, the slipstream effects will only be available if the propeller is on the wing, hence why the returned cl is equal to zero elsewhere.

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.
