plot_3d_rotor(rotor, save_filename='Rotor', save_figure=False, plot_data=None, show_figure=True, plot_axis=False, cpt=0, number_of_airfoil_points=21, color_map='turbid', alpha=1)[source]#

Creates a 3D visualization of a rotor with multiple blades.

Parameters:

  • rotor (Rotor) – RCAIDE rotor data structure containing geometry and blade information

  • save_filename (str, optional) – Name of file for saved figure (default: “Rotor”)

  • save_figure (bool, optional) – Flag for saving the figure (default: False)

  • plot_data (list, optional) – Existing plot data to append to (default: None)

  • show_figure (bool, optional) – Flag to display the figure (default: True)

  • plot_axis (bool, optional) – Flag to show coordinate axes (default: False)

  • cpt (int, optional) – Control point at which to plot the rotor (default: 0)

  • number_of_airfoil_points (int, optional) – Number of points used to discretize airfoil sections (default: 21)

  • color_map (str, optional) – Color specification for the rotor surface (default: ‘turbid’)

  • alpha (float, optional) – Transparency value between 0 and 1 (default: 1)

Returns:

None or plot_data – If plot_data provided, returns updated list of plot vertices

Return type:

list

Notes

Creates an interactive 3D visualization with:

  • Multiple blades at specified angular positions

  • Airfoil sections properly twisted and scaled

  • Optional coordinate axes

  • Adjustable view angles

generate_3d_blade_points(rotor, n_points, dim, i, aircraftRefFrame=True)[source]#

Generates 3D coordinate points for a single rotor blade.

Parameters:

  • rotor (Rotor) – RCAIDE rotor data structure containing blade geometry information

  • n_points (int) – Number of points around airfoil sections

  • dim (int) – Number of radial blade sections

  • i (int) – Blade number (0 to number_of_blades-1)

  • aircraftRefFrame (bool, optional) – Convert coordinates to aircraft frame if True (default: True)

Returns:

G –

Data structure containing generated points with attributes:
  • X, Y, Zndarray

    Raw coordinate points

  • PTSndarray

    Combined coordinate array

  • XA1, YA1, ZA1, XA2, YA2, ZA2ndarray

    Leading edge surface points

  • XB1, YB1, ZB1, XB2, YB2, ZB2ndarray

    Trailing edge surface points

Return type:

Data

Notes

Generates blade geometry by:

  1. Creating airfoil sections at specified radial positions

  2. Applying twist, chord, and thickness distributions

  3. Rotating to proper azimuthal position

  4. Converting to aircraft frame if requested
