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.

__init__(buttons_distance, angular_position=45, name='Rail Buttons')[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”.
