ABSTRACT:
A unitary, wide rim of fiber composite material for use in conjunction with flywheels for inertial energy storage apparatus, the rim being fabricated to minimize radial stresses and equalize hoop stresses ordinarily produced at high speed rotation of the flywheel. Novel fabrication techniques include varying the density of the rim as a function of radius by means of ballasting; and using a combination of layers of fibers having different modulus of elasticity. By utilizing the aforesaid novel fabrication techniques, a preferred embodiment of a unitary, thick flywheel rim achieves radial stress reduction to trivial levels and hoop stress equalization sufficient to permit extremely efficient energy storage as a function of flywheel weight.
