Info

- 28- Main Performance of Monopropellant Systems Thrust level: 0.5 ÷ 22N for satellites, up to 450 N for e.g. Ariane third stage auxiliary propulsion Impulse bit: ≥ 10 -2 Ns (with thruster minimum on-time of 20 ms) Thruster-spec. Impulse: ≤ 2300 Ns/kg [≡ve (m/s)] for continuous mode operation Thruster-spec. Impulse: ≈ 1900 ÷ 2200 Ns/kg for pulse mode operation System-spec. Impulse: ≤ 1860 Ns/kg
Advantages Simplicity and reliability (monopropellant) - 29- Lowest cost propulsion system (other than cold gas) Space storable for long periods (> 12 years demonstrated) Low thrust capability Moderate thrust levels available (≤ 400 N) Disadvantages Moderate Isp (≤ 2300 Ns/kg) with moderate Issp (< 1900 Ns/kg) resulting in medium/high system mass Limited life of catalyst Satellite outer surface contamination (NH3) moderate
