Latest Patents
One of Knowles' latest inventions is the Performance Arcjet Thruster. This advanced arcjet 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. By applying an electrical potential to both the anode and cathode, an electrical arc is generated in the arc chamber, facilitating the thermal heating and expansion of propellant as it is expelled through the nozzle. The thruster incorporates several innovative 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 allows for the recirculation of a small fraction of propellant from the constrictor region back into the bulk feed, as well as the regeneration and reaction of the propellant within the anode body structure.
