The NRL Multi-Megajoule Inertial-Inductive Energy Storage System

Abstract

In the NRL multi-megajoule pulse power system, energy is transferred from inertial storage (flywheels) to inductive storage by a self-excited homopolar generator. Reliable operation of the inertial storage at 5 MJ per flywheel is obtained from recent improvements in flywheel mounting, bearing lubrication, cooling and hydraulic power systems. This approach to energy conversion is only possible by use of copper-graphite fiber brushes which can follow rapid variations in wheel radius. Experimental efforts are being devoted to reducing the presently high frictional wear of these brushes.
