Abstract
The method and apparatus disclosed herein relates to a precision generator and distributor device for plasma and plasma discharge arc as it particularly applies to electro-thermal chemical gun system operations. A self-adjusting filament erodably controls the formation, energy content, consistency and dimension of a plasma arc in a capillary. Specifically, in cooperation with radially and longitudinally formed perforations in the capillary wall, the filament enables the distribution of a predetermined amount of plasma and plasma-ignited chemical fluid into segments and regions of a combustible chemical in a contiguous chamber to thereby control combustion and increase piezometric and ballistic efficiency of the gun system. More specifically, the filament enables the creation of a plasma arc that is sustainable, definite and consistent and one which yields high pressure and temperature at a reduced ohmic resistance for a given power supply.
