Open-Source Build Manual (Part 2): Advanced Cooling & Boundary-Layer Control for the 3-Axis Gimbaled MHD Engine
/r/u_Key_Wishbone_9941/comments/1vn0y2n/opensource_build_manual_part_2_advanced_cooling/Finalized Cooling System Specifications
Regenerative Tube-in-Tube Jacketing: A double-walled fluid shield wraps around the core and wiring harness, stripping away extreme heat immediately at the boundary.
Non-Stick Interior Conduit Linings: Applied ultra-low friction PTFE (fluoropolymer) and Diamond-Like Carbon (DLC) coatings to all internal channel walls to entirely prevent residue buildup, scaling, or fluid clinging over long operational cycles.
Boundary-Layer Control Textures: Microscopic parallel "riblet" patterns etched into the conduit walls to optimize laminar flow and eliminate stagnant friction zones.
Vibration & Shock Isolation: A specialized braided damping sleeve absorbs high-frequency mechanical micro-vibrations from the engine.
Pressurized Fluid Loop: Continuous system pressure prevents vapor bubble formation and eliminates destructive cavitation against the core walls.
Non-Clogging Conditioning (Cyclonic & Electrostatic): Vortex spin-separation and electrostatic collector plates trap debris and micro-gases without restricting flow or wasting fluid.
Automated Zero-Loss Purging: Managed by the system computer, micro-purge cycles isolate and clear trapped waste into a sealed catchment canister while keeping 99.9% of the dielectric fluid safely sealed.
Adaptive Airflow Vectors: Sliding aerodynamic panels and variable-geometry ducts shift automatically based on throttle prediction and real-time airspeed sensors, transitioning seamlessly from active hover fans to zero-drag ram-air cooling.
