RailButtons Class#

class rocketpy.RailButtons[source]#

Class that defines a rail button pair or group.

Variables:

RailButtons.buttons_distance (int, float) – Distance between the two rail buttons closest to the nozzle.
RailButtons.angular_position (int, float) – Angular position of the rail buttons in degrees measured as the rotation around the symmetry axis of the rocket relative to one of the other principal axis.
RailButtons.angular_position_rad (float) – Angular position of the rail buttons in radians.

__init__(buttons_distance, angular_position=45, name='Rail Buttons', rocket_radius=None)[source]#

Initializes RailButtons Class.

Parameters:

buttons_distance (int, float) – Distance between the first and the last rail button in meters.
angular_position (int, float, optional) – Angular position of the rail buttons in degrees measured as the rotation around the symmetry axis of the rocket relative to one of the other principal axis.
name (string, optional) – Name of the rail buttons. Default is “Rail Buttons”.
rocket_radius (int, float, optional) – Radius of the rocket at the location of the rail buttons in meters. If not provided, it will be calculated when the RailButtons object is added to a Rocket object.

evaluate_center_of_pressure()[source]#

Evaluates the center of pressure of the rail buttons. Rail buttons do not contribute to the center of pressure of the rocket.

evaluate_lift_coefficient()[source]#

Evaluates the lift coefficient curve of the rail buttons. Rail buttons do not contribute to the lift coefficient of the rocket.

evaluate_geometrical_parameters()[source]#

Evaluates the geometrical parameters of the rail buttons. Rail buttons do not contribute to the geometrical parameters of the rocket.

Prints out all the information about the Rail Buttons.

all_info()[source]#

Returns all info of the Rail Buttons.
