T-140 Hall Effect Thruster

image

The T-140 Hall Effect Thruster is an ideal size for north-south station keeping for large satellites. The T-140 operates at 1.8 to 4.5 kW and produces 160 to 300 mN of thrust with specific impulse values varying between 1,800 and 2,200 seconds, depending on operational conditions. This system has undergone successful demonstration testing and is currently under evaluation for complete system qualification testing. Two T-140’s are currently being modified to be used for a Hall thruster thermal modeling effort and a study on increasing propellant residence time in HET’s.
