This study exclusively focuses on exploring the property of flywheel geometry on its energy storage/deliver ability per unit mass, further defined as specific energy. In this paper we have studied various profiles of flywheel and the stored kinetic energy is calculated for the respective flywheel various profiles designed are solid disk, disk rim, webbed/section cut, arm/spoke flywheel. It shows that smart design of flywheel geometry could both have a major effect on the Specific Energy performance and reduce the operational loads exerted on the shaft/bearings due to reduced mass at high rotational speeds. Proficient flywheel design used to maximize the inertia of moment for minimum material used and guarantee high reliability and long life. FE analysis is carried out for different cases of loading on the flywheel and maximum stresses and total deformation are determined.
