Survey of Micro-Thrust Propulsion Options

Cube Sat - 5’th Annual Developers Workshop 2008

Conclusions

•

Some existing, and some newer thruster developments may be “borderline”

applicable to Cube Sat design envelopes.

•

Besides thruster performances and component size and mass, integration

issues have to be considered:

•

Need for improved subsystems, high pressure tanks

•

Power issues

•

Some

newer developments offer exciting applications:

•

VACCO developed Butane thrusters combine low power piezovalve

technology

and low-pressure compact propellant storage for efficient attitude control and low

delta-v in a simple system.

•

JPL developed Miniature xenon ion engine technology (MiXI) offers potential of

exciting new CubeSat

missions requiring high-delta-V for large (multiple cube) Cube

Sat busses using deployable arrays.
