Abstract
An example flywheel energy storage device includes a fiber-resin composite shell having an elliptical ovoid shape. The example device also includes an axially oriented internal compressive support between the axial walls of the shell. The example device also includes an inner boss plate and an outer boss plate on each side of the shell. The example device also includes a plurality of radially oriented, fiber-resin composite helical wraps forming the shell and coupling the shell to the inner and outer boss plates for co-rotation and torque transfer. The example device also includes boss plate attachments on internal boss plate supports to mount the shell for co-rotation and torque transfer via resin bonding, friction, and compression between the inner and outer boss plates.
Claims9
A flywheel energy storage device, comprising:
- a filament wound composite shell having an elliptical ovoid shape with axial walls and coupled to a rotating shaft by paired structural flange plates concentrically disposed on either side of the shaft;
- an axially oriented internal compressive support between the axial walls;
- an inner boss plate and an outer boss plate on each side of the shell;
- boss plate attachments on internal boss plate supports to mount the shell for co-rotation and torque transfer about the shaft;
- and
- wherein the shell is supported on each end of the shaft by bearings.
