class Body_of_Revolution_Nacelle(Nacelle):
    """
    A nacelle design generated by rotating an airfoil profile around a central axis, 
    commonly used for podded engine installations.

    Attributes
    ----------
    tag : str
        Unique identifier for the nacelle component, defaults to 'body_of_revolution_nacelle'
        
    Airfoil : Data
        Container for airfoil profile data used to generate the nacelle shape, 
        defaults to empty Data()

    Notes
    -----
    A body of revolution nacelle is created by rotating an airfoil section about a 
    central axis, creating an axisymmetric shape. This approach is commonly used for:
    
    * Podded engine installations
    * Streamlined auxiliary power unit enclosures
    * External fuel tank designs
    
    **Major Assumptions**
    
    * Axisymmetric geometry
    * Smooth surface transitions
    * No significant flow separation
    
    **Definitions**

    'Body of Revolution'
        A three-dimensional shape created by rotating a two-dimensional profile 
        around a central axis
        
    'Highlight Radius'
        The radius at the forward-most point of the nacelle inlet
