plot_rotor_disc_performance

plot_rotor_disc_performance(prop, outputs, i=0, title=None, save_figure=False)

Generate plots of rotor disc aerodynamic performance distributions.

Parameters:

• prop (Data) – Rotor properties data structure

• outputs (Data) –

  Rotor analysis outputs containing:

  • disc_azimuthal_distributionarray

    Azimuthal angles around disc [rad]

  • disc_radial_distributionarray

    Radial positions on disc [m]

  • disc_thrust_distributionarray

    Local thrust distribution

  • disc_torque_distributionarray

    Local torque distribution

  • disc_effective_angle_of_attackarray

    Local effective angle of attack [rad]

  • disc_axial_induced_velocityarray

    Local axial induced velocity [m/s]

  • disc_tangential_induced_velocityarray

    Local tangential induced velocity [m/s]

• i (int, optional) – Time index for plotting, default 0

• title (str, optional) – Custom plot title, default None

• save_figure (bool, optional) – Save figure to file if True, default False

Returns:

fig – Figure containing five polar subplots:

• Thrust distribution

• Torque distribution

• Local blade angle

• Axial velocity

• Tangential velocity

Return type:

matplotlib.figure.Figure

Notes

All plots use:

• Polar coordinates (azimuth, radius)

• Jet colormap for contours

• Consistent number of contour levels

• Colorbar showing scale

Definitions

‘Thrust Distribution’
