Rocket Plots Class#

class rocketpy.plots.rocket_plots._RocketPlots[source]#

Class that holds plot methods for Rocket class.

Variables:: _RocketPlots.rocket (Rocket) – Rocket object that will be used for the plots.

__init__(rocket)[source]#

Initializes _RocketPlots class.

Parameters:: rocket (Rocket) – Instance of the Rocket class
Return type:: None

total_mass()[source]#

Plots total mass of the rocket as a function of time.

Return type:: None

reduced_mass()[source]#

Plots reduced mass of the rocket as a function of time.

Return type:: None

static_margin(*, filename=None)[source]#

Plots static margin of the rocket as a function of time.

Parameters:: filename (str | None, optional) – The path the plot should be saved to. By default None, in which case the plot will be shown instead of saved. Supported file endings are: eps, jpg, jpeg, pdf, pgf, png, ps, raw, rgba, svg, svgz, tif, tiff and webp (these are the formats supported by matplotlib).
Return type:: None

stability_margin()[source]#

Plots static margin of the rocket as a function of time.

Return type:: None

drag_curves(*, filename=None)[source]#

Plots power off and on drag curves of the rocket as a function of time.

Parameters:: filename (str | None, optional) – The path the plot should be saved to. By default None, in which case the plot will be shown instead of saved. Supported file endings are: eps, jpg, jpeg, pdf, pgf, png, ps, raw, rgba, svg, svgz, tif, tiff and webp (these are the formats supported by matplotlib).
Return type:: None

thrust_to_weight()[source]#: Plots the motor thrust force divided by rocket weight as a function of time.

draw(vis_args=None, plane='xz', *, filename=None)[source]#

Draws the rocket in a matplotlib figure.

Parameters:

vis_args (dict, optional) –

Determines the visual aspects when drawing the rocket. If None, default values are used. Default values are:

{
    "background": "#EEEEEE",
    "tail": "black",
    "nose": "black",
    "body": "black",
    "fins": "black",
    "motor": "black",
    "buttons": "black",
    "line_width": 2.0,
}

A full list of color names can be found at: https://matplotlib.org/stable/gallery/color/named_colors

plane (str, optional) – Plane in which the rocket will be drawn. Default is ‘xz’. Other options is ‘yz’. Used only for sensors representation.
filename (str | None, optional) – The path the plot should be saved to. By default None, in which case the plot will be shown instead of saved. Supported file endings are: eps, jpg, jpeg, pdf, pgf, png, ps, raw, rgba, svg, svgz, tif, tiff and webp (these are the formats supported by matplotlib).

_draw_aerodynamic_surfaces(ax, vis_args, plane)[source]#: Draws the aerodynamic surfaces and saves the position of the points of interest for the tubes.

_draw_nose_cone(ax, surface, position, drawn_surfaces, vis_args)[source]#: Draws the nosecone and saves the position of the points of interest for the tubes.

_draw_tail(ax, surface, position, drawn_surfaces, vis_args)[source]#: Draws the tail and saves the position of the points of interest for the tubes.

_draw_fins(ax, surface, position, drawn_surfaces, vis_args)[source]#: Draws the fins and saves the position of the points of interest for the tubes.

_draw_generic_surface(ax, surface, position, drawn_surfaces, vis_args, plane)[source]#: Draws the generic surface and saves the position of the points of interest for the tubes.

_draw_tubes(ax, drawn_surfaces, vis_args)[source]#: Draws the tubes between the aerodynamic surfaces.

_draw_motor(last_radius, last_x, ax, vis_args)[source]#: Draws the motor from motor patches

_generate_motor_patches(total_csys, ax)[source]#: Generates motor patches for drawing

_draw_nozzle_tube(last_radius, last_x, nozzle_position, ax, vis_args)[source]#: Draws the tube from the last surface to the nozzle position.

_draw_rail_buttons(ax, vis_args)[source]#: Draws the rail buttons of the rocket.

_draw_center_of_mass_and_pressure(ax)[source]#: Draws the center of mass and center of pressure of the rocket.

_draw_sensors(ax, sensors, plane)[source]#: Draw the sensor as a small thick line at the position of the sensor, with a vector pointing in the direction normal of the sensor. Get the normal vector from the sensor orientation matrix.

all()[source]#

Prints out all graphs available about the Rocket. It simply calls all the other plotter methods in this class.

Return type:: None
