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.
