class Turbine(Converter):
"""
A turbine component model for gas turbine and turbofan engines.
Attributes
----------
tag : str
Identifier for the turbine. Default is 'Turbine'.
mechanical_efficiency : float
Efficiency of mechanical power transmission. Default is 1.0.
polytropic_efficiency : float
Efficiency of the expansion process accounting for losses. Default is 1.0.
Notes
-----
The Turbine class models the expansion and work extraction process in a
turbine stage. The model includes:
* Work extraction calculations
* Pressure ratio effects
* Temperature changes
* Efficiency losses
* Mechanical power transmission
* Real gas effects
**Major Assumptions**
* Efficiencies do not change with varying conditions
**Definitions**
'Mechanical Efficiency'
Ratio of shaft power output to gas power extraction
'Polytropic Efficiency'
Measure of expansion process efficiency accounting for losses
