class aviary.utils.engine_deck_conversion.AtmosCalc(**kwargs)

Bases: ExplicitComponent

Calculates T2 and P2 given static temperature and pressure

compute(inputs, outputs)

Compute outputs given inputs. The model is assumed to be in an unscaled state.

Parameters:

• inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

• outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

• discrete_inputs (dict or None) – If not None, dict containing discrete input values.

• discrete_outputs (dict or None) – If not None, dict containing discrete output values.

initialize()

Perform any one-time initialization run at instantiation.

setup()

Declare inputs and outputs.

Available attributes:

name pathname comm options

class aviary.utils.engine_deck_conversion.CalculateIdle(**kwargs)

Bases: ExplicitComponent

Calculates idle conditions of a GASP engine at a specified flight condition Vectorized to calculate values for entire flight regime

compute(inputs, outputs)

Compute outputs given inputs. The model is assumed to be in an unscaled state.

Parameters:

• inputs (Vector) – Unscaled, dimensional input variables read via inputs[key].

• outputs (Vector) – Unscaled, dimensional output variables read via outputs[key].

• discrete_inputs (dict or None) – If not None, dict containing discrete input values.

• discrete_outputs (dict or None) – If not None, dict containing discrete output values.

aviary.utils.engine_deck_conversion.EngineDeckConverter(input_file, output_file, data_format: EngineDeckType)

Converts FLOPS- or GASP-formatted engine decks into Aviary csv format. FLOPS decks are changed from column-delimited to csv format with added headers. GASP decks are reorganized into csv. T4 is recovered using assumptions used in GASPy. Data points whose T4 exceeds T4max are removed.

Parameters:

• input_file ((str, Path)) – path to engine deck file to be converted

• output_file ((str, Path)) – path to file where new converted data will be written

• data_format ((EngineDeckType)) – data format used by input_file (FLOPS or GASP)

class aviary.utils.engine_deck_conversion.EngineDeckType(value, names=<not given>, *values, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

FLOPS = 'FLOPS'

GASP = 'GASP'

GASP_TS = 'GASP_TS'
