class Aviation_Gasoline(Propellant):
"""
A class representing aviation gasoline (avgas) fuel properties.
Attributes
----------
tag : str
Identifier for the propellant ('Aviation_Gasoline')
density : float
Fuel density in kg/m³ (721.0)
specific_energy : float
Specific energy content in J/kg (43.71e6)
Notes
-----
This class implements properties for aviation gasoline (avgas), commonly used in
piston-engine aircraft.
**Definitions**
'Avgas'
Aviation gasoline, a high-octane fuel specifically formulated for
aircraft piston engines
'Specific Energy'
The amount of energy per unit mass of fuel, indicating the fuel's
energy content
**Major Assumptions**
* Properties are for standard temperature and pressure conditions
* Fuel is assumed to be in liquid phase

"""
def __defaults__(self):
"""
Sets default values for aviation gasoline properties.
Notes
-----
Initializes standard properties for AVGAS including density and specific
energy content. Values are based on industry standard specifications for
AVGAS 100LL.
