Hybrid Propulsion System (FSPS Hybrid Drives)
Patent Pending #63/783,874
Chemical rockets got us into orbit — but they won’t take us to Mars, and they certainly won’t bring us back with crew, cargo, and confidence.
Our FSPS Hybrid Drives — in development for over a decade — represent a next-generation propulsion system that redefines thrust, efficiency, and adaptability for deep space missions.
Unlike conventional engines limited to one or two propellants, the FSPS Hybrid Drive supports multiple fuel combinations, with in-flight adaptability based on destination and mission phase. Our selected propellants include:
* Carbon Dioxide (CO2) — Abundant on Mars, moons, comets, and other celestial bodies. Ideal as a base propellant for ISRU-based operations.
* Hydroxylammonium Nitrate (HAN) — A high-performance, non-cryogenic monopropellant that’s safer and denser than hydrazine. Blended with our advanced combustion-enhancing additives (Six Component Additive Formulation).
* Hydrogen (H2) — Lightweight, high-energy, and easily harvested via electrolysis across multiple planetary environments. Offers maximum exhaust velocity.
Key Features of the FSPS Hybrid Drive:
Microwave-Laser Ignition
High-powered plasma ignition system using microwave-laser convergence within a magnetically confined chamber forged from rare earth metals and next-gen alloys.
Extreme Thrust & Plasma Efficiency
Generates high-energy plasma flow delivering thrust levels significantly higher than conventional propulsion, while offering over 5x the efficiency.
Multi-Propellant Injection Control
Intelligent switching between CO?, HAN, and H? for optimal thrust, range, and fuel conservation across mission stages.
Advanced Thrust Vectoring
Uses electromagnetic and electric field shaping for fine-tuned control during low-gravity landings, orbit matching, and long-duration burns.
ISRU-Optimized Design
Built for vacuum and thin-atmosphere operation, enabling propellant sourcing directly from the target body — reducing fuel mass and launch burden.
