fastga_he.models.propulsion.components.source.simple_turbo_generator.components.pre_lca_prod_weight_per_fu module

class fastga_he.models.propulsion.components.source.simple_turbo_generator.components.pre_lca_prod_weight_per_fu.PreLCATurboGeneratorProdWeightPerFU(**kwargs)[source]

Bases: ExplicitComponent

Computation of the weight per functional unit considering the replacement necessary during the lifespan of the aircraft. For the default value of the average lifespan of the turbogenerator, the value is taken from [TSRP+24] for short term technologies.

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.

compute_partials(inputs, partials, discrete_inputs=None)[source]

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.
