fastga_he.models.propulsion.components.source.turboshaft.components.perf_required_power module

class fastga_he.models.propulsion.components.source.turboshaft.components.perf_required_power.PerformancesRequiredPower(**kwargs)

Bases: ExplicitComponent

In addition to the power required on the shaft we might also want to add a mechanical offtake straight on the shaft. This component simply adds that possibility for users but the default will be 0.0. More advanced way to define this offtake (like proper physical components) might come in the future.

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.

static smooth_power(power)

In some integration tests, some values of power have been seen going to absurd values, this is a protection against it.
