Abstract :
Optimal energy systems is currently designing and manufacturing flywheel based energy storage systems that are being used to provide pulses of energy for charging high voltage capacitors in a mobile military system. These systems receive their energy from low voltage vehicle bus power (<480 VDC) and provide output power at over 10,000 VDC without the need for DC-DC voltage conversion electronics. This energy conversion is accomplished through the use of OES patented ultra high-speed flywheel power module (FPoM) technology. In this paper, adaptation of the OES FPoM technology to energy storage for electromagnetic aircraft launch system (EMALS) applications is described. Physical system design parameters are summarized for the FPoM. Transient PSPICE electrical and MSC/Nastran FEA thermal analyses characterize operation and response in a conceptual EMALS energy storage environment.
