Legion Intensive Cycle Engine: Pulse-Detonation Thermodynamic System for Sustainable Energy

Abstract

This paper presents the updated architecture of the Legion Intensive Cycle Engine (LEGION). The system utilizes a "Twin-Flow" mechanism powered by controlled Hydrogen-Oxygen (H2+O2) detonation within a Tantalum-Hafnium Carbide (Ta4HfC5) core. A key innovation is the management of Thermal

Dissociation at 3200°C, where the working fluid splits into a high-velocity mixture of steam (85%) and reactive gases (15%). By employing a high-frequency "Heartbeat" loop and Flash-Electrolysis (SOEC), the system prevents material thermal shock and achieves immediate fuel regeneration, creating a Quasi-Steady State resonance loop.
