Abstract
Flywheel energy storage (FES) systems have demonstrated the potential to store very high amounts of energy with minimum weight when compared to chemical battery systems. A high energy density flywheel is needed in order to achieve a lightweight design that is competitive with chemical battery systems, however, there are major concerns regarding the safety of operation and the structural integrity of critical components, such as the rim, hub, and shaft. The stresses at high speeds (up to 80,000 rpm) can be very high and cause fiber breakage, matrix microcracking, debonding, and delamination, which lead to premature failure of the rotor design. The consequences of failures of the rotor are a major concern regarding the implementation of a flywheel energy storage system for a spacecraft system and therefore a design approach that includes the use of health monitoring is necessary in order to ensure fail-safe operation.
