Electric Flywheel Basics. The core element of a flywheel consists of a rotating mass, typically axisymmetric, which stores rotary kinetic energy E according to (Equation 1) E = 1 2 I ω 2 [ J], where E is the stored kinetic energy, I is the flywheel moment of inertia [kgm 2 ], and ω is the angular speed [rad/s].

By storing the thermal energy during the night and releasing it during the day, this solution allows electricity usage at the lowest prices and avoids the peaks. By spreading thermal energy production over 24 hours, TES can reduce chiller load by up to 70%*. *Measured differences between equivalent systems designed with and without TES.

Applications in an aircraft carrier include [25] weapons elevators, aircraft elevators, hangar doors, rudder mechanisms, and propulsion systems. Propulsion systems were discussed in the previous section. The weapons elevators have a load capacity of 42,000 pounds and must move at 2 feet per second even when the sea is rough.

In the field of flywheel energy storage systems, only two bearing concepts have been established to date: 1. Rolling bearings, spindle bearings of the "High Precision Series" are usually used here. 2. Active magnetic bearings, usually so-called HTS (high-temperature superconducting) magnetic bearings.
