class Segment(Component):
"""
A component representing a single cross-sectional segment of a nacelle. Used to build
up complex nacelle geometries through a series of connected sections.
Attributes
----------
tag : str
Unique identifier for the segment, defaults to 'segment'
orientation_euler_angles : list
Rotation angles [roll, pitch, yaw], defaults to [0.0, 0.0, 0.0]
percent_x_location : float
Longitudinal position as percentage of nacelle length, defaults to 0
percent_y_location : float
Lateral position as percentage of nacelle width, defaults to 0
percent_z_location : float
Vertical position as percentage of nacelle height, defaults to 0
height : float
Vertical dimension of the segment cross-section, defaults to 0
width : float
Lateral dimension of the segment cross-section, defaults to 0
curvature : float
Shape parameter controlling cross-section corner rounding using super-ellipse
formulation, defaults to 2
Notes
-----
Segments are used to build up the complete nacelle geometry through a series of
cross-sections. Each segment's position is defined as a percentage of the overall
nacelle dimensions, allowing for flexible scaling and positioning.
**Major Assumptions**
* Segments are connected in sequence to form a continuous surface
* Cross-sections are defined by height, width, and curvature parameters
* Super-ellipse formulation used for cross-section shape
**Definitions**
'Super-ellipse'
Mathematical curve used to create smooth, rounded rectangular shapes with
controllable corner curvature

"""
Container class for managing nacelle segments. Provides organization and
access methods for segment components.
Notes
-----
This container is designed to hold and manage Segment objects that define
the nacelle shape. It inherits from the base Container class and provides
specialized functionality for nacelle segments.
