HYDRATE: A Zero-Emission Direct Drive Parallel Hybrid Turbofan for Personal Jets

HYDRATE represents a transformative leap in zero-emission aviation propulsion, integrating a hydrogen-burning regenerative turbine with MagLev Aero’s proprietary maglev rim drive. This parallel hybrid system optimizes fuel efficiency, reducing cruise fuel consumption by over 20%, while increasing bypass ratios and thermal efficiency—key limitations in current small turbofans. Unlike traditional hybridization efforts focused on large commercial aircraft with marginal efficiency gains, HYDRATE targets the underserved Very Light Jet (VLJ) market, where existing propulsion remains outdated. By leveraging magnetic gearing, tip-driven assistance, and regenerative energy use, the system achieves superior throttle response, reduced complexity, and increased operational flexibility. Quantitatively, the design enables optimized thrust distribution throughout flight, compensating for altitude variations and improving safety. The approach offers a scalable pathway toward zero-emission propulsion with near-term applications in personal jets and potential expansion into larger commercial aviation through NASA’s HyTEC initiative, setting a new standard for sustainable, high-performance flight.
