Micro Mono-Propellant Thruster
The Monopropellant Thruster developed by AIT is a low thrust (less than 1N) propulsion solution. Usage of hydrogen peroxide not only results in a high impulse density but promises also significantly reduced development and operational costs. Especially due to the latter, such a system could replace the present hydrazine propulsion systems.
Envisioned application for this system includes attitude control and accurate positioning of medium and small satellites.
Characteristics and measured performance data are summarized in the following table:
| Thrust | 150 – 900 mN |
| Specific Impulse (vacuum) | 153 s |
| Thruster mass | less than 60 g |
| Propellant | Hydrogen Peroxide (87.5%) |
| Power | less than 60 g |
The present development level is roughly equivalent to TRL 3. Further developments are ongoing.
