class Propeller(Rotor):
"""
A propeller component model for aircraft propulsion, inheriting from the base Rotor class.
Attributes
----------
tag : str
Identifier for the propeller. Default is 'propeller'.
orientation_euler_angles : list
Vector of angles [rad] defining propeller orientation [θ, φ, ψ].
Default is [0., 0., 0.] for X-direction thrust in vehicle frame.
use_2d_analysis : bool
Flag for using 2D aerodynamic analysis. Default is False.
Notes
-----
The Propeller class models fixed or variable pitch propellers for aircraft
propulsion. It includes capabilities for:
* Forward flight performance analysis
* Fixed and variable pitch operation
* Blade element momentum theory calculations
* Efficiency optimization
* Acoustic analysis
The model assumes:
* Axial inflow (unless modified by orientation angles)
* Rigid blades
* Quasi-steady aerodynamics
* No blade-to-blade aerodynamic interference
* No compressibility effects (unless explicitly modeled)
**Definitions**
'Variable Pitch'
Capability to change blade pitch angle during operation
'Euler Angles'
Set of three angles defining propeller orientation relative to vehicle frame
'2D Analysis'
Use of two-dimensional airfoil data for blade section analysis
