Survey of Micro-Thrust Propulsion Options
Cube Sat - 5’th Annual Developers Workshop 2008
•
Electric Propulsion: Precision attitude control or high-Isp
delta-V
•
Miniature Ion Propulsion (MiXI):
•
JPL developed miniature ion engine technology may satisfy Cube sat design envelope for multi-
cube (3-cube “brick”, 6 cube “six pack”) architectures with deployable arrays.
•
Power limitations may require MiXI
to be operated in throttle mode at limited thrust, however, at
T/W ratios not unlike on larger EP propelled spacecraft.
•
Vacuum Arc Thruster:
•
Developed by Almeda
Applied Sciences for micro-
and formation flying control
•
Cube sat architectures have already been explored (single cube).
•
Primarily suited for attitude control due to inherently pulsed operation and low total impulse.
•
Pulse Plasma Thrusters:
•
Smaller PPT versions have been developed for micro-sat application (Dawgstar).
•
Primarily suited for attitude control due to inherently pulsed operation and low total impulse.
