Abstract
The serial arc plasma injectors device disclosed herein enables the formation of a segmented, isolated chain of plasma arcs which are incubated to form a specified energy level of plasma discharge tailored to initiate ignition and establish efficient combustion in a particular segment of a propellant mass. The device includes a capillary in which a conductive path comprising electrodes is maintained. Particularly, specialized electrodes provide geometric and dimensional flexibility to establish plasma arc and plasma discharge characteristics that are compatible with different zones of the propellant mass. The specialized electrodes in combination with discharge vents enable the development of a series of regions in the capillary through which plasma discharge is introduced into the propellant mass to selectively initiate ignition and promote efficient combustion.
