Title: The Innovations of William W. Smith
Introduction
William W. Smith is a notable inventor based in Seattle, WA (US). He holds a total of six patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on advancements in propulsion systems, particularly in the development of arcjet thrusters.
Latest Patents
One of his latest patents is the Performance Arcjet Thruster. This innovative thruster features a body that defines a constrictor and nozzle, which together constitute an anode and form an arc chamber. An elongated rod serves as a cathode, spaced from the constrictor by a gap that is generally coextensive with the arc chamber. An electrical potential is applied to both the anode and cathode, generating an electrical arc in the arc chamber. Propellant is supplied to the arc chamber during the generation of the arc, resulting in thermal heating and expansion of the propellant as it exits through the nozzle. The thruster incorporates several features that enhance its performance, including the use of propellant blends with high specific impulse additives and the injection of these additives into the bulk propellant feed at the cathode tip. Additionally, it utilizes recirculation of a small fraction of propellant from the constrictor region and regeneration of the bulk propellant feed within the anode body.
