The introduction and utilization of modern weapon systems on shipboard platforms demands new high energy storage capacity devices with rapid charge/discharge capacities. Flywheel-based systems are particularly attractive for this purpose due to their high fatigue life, reliability, high efficiency and rapid rate of discharge. However, one of the main factors limiting the energy storage capacity of a flywheel is the mechanical stresses developed in the flywheel rotor due to centrifugal forces and inertia effects, which can lead to structural failure. Therefore, introducing materials to flywheels with high specific strength, such as carbon fiber reinforced composites and carbon nanotubes (CNTs), will enable higher tip velocities and thus higher energy storage capacity. For example, by utilizing the increased strength of CNTs, a ~12 improvement in energy density is possible over state-of-the-art graphite composite flywheels. To address the solicited DoD need for advanced shipboard energy storage solutions, PM&AM Research, in collaboration with Texas A&M University, propose to develop a novel hybrid CNT-based flywheel energy storage system for pulse power applications. This innovative approach will improve energy storage capabilities beyond state-of-the-art systems. Through design optimization, the hybrid flywheel will exhibit improved strength, safety, and energy-storage by cost-effectively achieving higher speeds.
