HX-1 Solid-State Hydrogen Turboelectric Cycle: Architecture, Loofah–CNT Fuel Modules, and Defensive Prior-Art Disclosure

This document presents the HX-1 Solid-State Hydrogen Turboelectric Cycle, a next-generation propulsion architecture combining a high-efficiency Brayton core, a compact bottoming cycle, distributed electric propulsion (DEP), and modular loofah–CNT solid-state hydrogen storage vessels. The system introduces a dual-hydrogen strategy: (1) solid-state loofah–CNT modules serving as the primary fuel source, and (2) an optional liquid-hydrogen (LH₂) cryogenic pod functioning exclusively as a high-grade thermal sink for turbine cooling, condensation, and power-electronics thermal management.

HX-1 integrates a multifunctional thermal-interface material, enabling conformal heat transport, vibration damping, and multi-domain coupling between hydrogen subsystems, condensers, generators, inverters, and DEP actuators. Together, these features raise the effective turbine inlet temperature while lowering the sink temperature of the bottoming cycle, pushing the real-cycle efficiency toward the theoretical Carnot limit.

The document includes a detailed system architecture, mission-level hydrogen-consumption model, operational endurance tables, TikZ system diagram, nomenclature, and an explicit defensive-publication declaration. By publicly releasing this specification, the author establishes global prior art for the HX-1 turboelectric propulsion system and all associated thermodynamic, thermal-material, and solid-state hydrogen-storage integrations as described herein.
