Abstract:
A rotational body, to a rotor and to a flywheel energy storage unit having such rotational bodies is disclosed and a method for the production of a rotational body, having a cylinder jacket at least partially wound using a fiber-reinforced composite. A cylinder axis includes open cylinder base surfaces, whereby the cylinder jacket, with its inside facing the axis of rotation and its outside oriented in the opposite direction, has a length parallel to the axis of rotation of more than twice the outer diameter of the rotational body, and it has a wall thickness that is less than 12.5% of the outer diameter. The fiber-reinforced composite of the cylinder jacket has a layered structure in the radial direction comprising helical layers of fibers which extend along the axis of rotation and whose orientation along the helical fiber angle is less than 35° relative to the axis of rotation.

Claim (Index 23):
A flywheel energy storage unit to store a large energy content, having one or more rotors that are each surrounded by a machine housing, comprising an internally hollow cylindrical rotational body having a cylinder jacket that is at least partially wound using a fiber-reinforced composite, also having a cylinder axis as the axis of rotation and having open cylinder base surfaces, whereby the cylinder jacket, with its inside facing the axis of rotation and with its outside oriented in the opposite direction, has a length parallel to the axis of rotation of more than twice the outer diameter of the rotational body, and it has a wall thickness that is less than 15% of the outer diameter, whereby the fiber-reinforced composite of the cylinder jacket has a layered structure in the radial direction comprising several helical layers of fibers which extend along the axis of rotation, with an orientation along the helical fiber angle relative to the axis of rotation, and comprising several circumferential layers which are arranged tangentially thereto over the length (LM) of the cylinder jacket and which consist of fibers whose orientation along the circumferential fiber angle is greater than 80\u00b0 relative to the axis of rotation, whereby the helical layers and the circumferential layers are arranged alternatingly one above the other, and all of the helical layers are arranged in the inner one-third of the cylinder jacket, as seen in the radial direction, whereby the rotor can be accelerated by a motor-generator unit of the flywheel energy storage unit in order to store electric energy and it can be braked in order to release electric energy.
