class fastga_he.models.propulsion.components.connectors.speed_reducer.components.lcc_speed_reducer_cost.LCCSpeedReducerCost(**kwargs)[source]

Bases: ExplicitComponent

Computation of speed reducer purchase price, which is based on the gearbox provided by https://www.mohawkaero.com/product-page/ak7-gearbox. The gearbox weight is obtained from https://www.youtube.com/watch?v=M10O7S89GE8.

Store some bound methods so we can detect runtime overrides.

initialize()[source]

Perform any one-time initialization run at instantiation.

setup()[source]

Declare inputs and outputs.

Available attributes:

name pathname comm options

compute(inputs, outputs, discrete_inputs=None, discrete_outputs=None)[source]

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.
