CylindricalTank Class

class rocketpy.CylindricalTank

Class to define the geometry of a cylindrical tank. The cylinder has its zero reference point at its center (i.e. half of its height). This class inherits from the TankGeometry class. See the TankGeometry class for more information on its attributes and methods.

__init__(radius, height, spherical_caps=False, geometry_dict={})

Initialize CylindricalTank class. The zero reference point of the cylinder is its center (i.e. half of its height). Therefore the its height coordinate span is (-height/2, height/2).

Parameters:

• radius (float) – Radius of the cylindrical tank, in meters.

• height (float) – Height of the cylindrical tank, in meters.

• spherical_caps (bool, optional) – If True, the tank will have spherical caps at the top and bottom with the same radius as the cylindrical part. If False, the tank will have flat caps at the top and bottom. Defaults to False.

• geometry_dict (dict, optional) – Dictionary containing the geometry of the tank. See TankGeometry.

add_spherical_caps()

Adds spherical caps to the tank. The caps are added at the bottom and at the top of the tank with the same radius as the cylindrical part. The height is not modified, meaning that the total volume of the tank will decrease.
