Engineering Analysis for LINUS Imploding Liquid Liner Systems
MetadataShow full item record
The Center for Electromechanics (CEM) of The University of Texas at Austin has completed an engineering analysis of controlled imploding liquid metal liner (LINUS) devices for the Naval Research Laborotory (NRL). NRL is involved in the development of this type of high energy density system which has potential use in the areas of compact fusion and pulsed electrical power sources and advanced weapon systems. Although NRL is presently operating two experimental machines, HELIUS and LINUS-0, the mechanical stresses, electromechanical behavior, and dynamic behavior of larger LINUS-type devices operating repetitively at elevated temperatures have not been completely established. The limitations imposed by these considerations significantly affect the design of these devices. In this paper, dynamic instabilities, material considerations, injection systems, rotor geometries, mechanical stresses and the effect of elevated temperatures are discussed. The effect of these items also influence the choice between a rotating or a stationary reactor vessel.
