Title: Development of Next-Generation Composite Flywheel Design for Shock and Vibration Tolerant, High Density Rotating Energy Storage
Agency / Branch: DOD / NAVY
Contract: N00014-13-P-1205
Award Amount: $79,183.00


PowerTHRU Corporation proposes to meet or exceed the requirements of this STTR by utilizing its extensive experience in carbon fiber based high speed flywheel systems, to design and build a 100K RPM flywheel system. Unlike steel flywheel technologies that are limited by the speed in which they can safely rotate, PowerTHRU has already demonstrated that 50,000 RPM carbon fiber flywheels can be designed and operated safely in the commercial and military markets by distributing over 950 active systems from 2004 - 2012. PowerTHRU shall rely on that field level experience to achieve 100K RPM with an increased mass. THE BENEFIT to this improved design will offer an immediate opportunity in the commercial UPS industry to bridge the power outage time between loss of grid power and generator start-up, in a safe and efficient manner. THE BENEFIT of the carbon fiber system is that even in the case of an ultimate system failure, it would be a benign event that poses no risk to any personnel or equipment in the area, which allows the system to be used not only in the commercial UPS industry, but also in any military or commercial application that requires pulse power.
