OVERVIEW

The AIS-gPPT3-1C Single-Channel Gridded Pulsed Plasma Thruster represents the latest iteration of sub-joule micro-PPTs at Applied Ion Systems. This thruster radically diverges from conventional and standard pulsed plasma thrusters, with a specific emphasis on accessibility and miniaturization, geared towards PocketQubes and Cubesats. The gPPT line thrusters from Applied Ion Systems features an unconventional flat stacked-plate geometry, aiming to significantly reduce the space required for a pulsed plasma thruster, and offers a new solution for a new class of ultra-low power, low-cost sub-Joule PPTs.

The simple construction and extremely low cost of the gPPT3 lends itself for prototyping, laboratory testing, academic learning, and orbital demonstrations, as well as the ability for easy modifications and geometry changes to test various configurations for fuel, electrode spacing, and output nozzles. The gPPT3 is available as a single stand-alone thruster head for user interfacing for their own PPT drivers, or can be used with the AIS-gPPT3-1C Integrated Propulsion Module.
