LMP-103S is an environmentally benign monopropellant based on the energetic material Ammonium DiNitramide (ADN). It offers a ≥30% density impulse improvement as compared to monopropellant hydrazine, while significantly reducing handling risk and costs, resulting in up to 72% cost reductions at launch site[1].
Propellant Blend:
- ADN: 63%
- Methanol: 18.4%
- Ammonia: 4.6%
- Water: 14%
Key Benefits:
- Higher Performance vs Hydrazine
- ISP >6%
- Density >24%
- Density Impulse >30%
- Reduced Personal and Environmental Hazards
- Simpler and Less Costly Handling an Transport
