fastga_he.models.propulsion.components.loads.sm_pmsm.components.perf_mechanical_losses module

class fastga_he.models.propulsion.components.loads.sm_pmsm.components.perf_mechanical_losses.PerformancesMechanicalLosses(**kwargs)

Bases: ExplicitComponent

Computation of the mechanical losses result from frictions between gas and rotating solid or between rotating solid and stationary solid. This is obtained from part II.3.3 in [Tou20].

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.
