From Anyons to Armor: Refactoring a Phased-Array Concept
#Shouts to Copilot and associated AI deliverance for this beautiful iceskate lets make hockey dangerously fast!
Good ideas evolve. This post is a refactor of a previous concept, tracing the evolution of a single idea from the quantum realm to two distinct, powerful, real-world applications: one for propulsion and one for defense.
The core concept remains the same: using a tri-phase (0°, 120°, 240°) traveling wave to generate directional force. But *how* we apply that wave, and *what* it acts upon, has fundamentally changed.
Part 1: The Quantum Origin (Briefly)
The idea started with the Anyon-Edge Surface Translation Device. At cryo-temperatures and high magnetic fields, a 2D material's edge becomes a perfect 1D "highway" for electrons. The idea was to use phased RF gates to create a traveling potential wave, "surfing" electrons along this edge to drag a microscopic magnetic sled. It was a true nano-machine, generating nanoNewtons of force. (For the original schematic, see the previous post).
Part 2: Macro Translation 2.0 - The External Ablative Thruster
The first leap was to translate this to the macro world. We replace the quantum components with physical ones:
- RF Gates → Piezoelectric (PZT) Impingers
- 2D Electron Gas → Reactive Bi-Layer Propellant
- Traveling Potential Wave → Traveling Stress Wave
Our initial design had the propellant *inside* the engine. A refactor led to a much cleaner design: the External Ablative Plate Thruster (EAPT). Here, the "engine" is the skate, and the "propellant" is the ice it skates on.
The EAPT engine (the "skate") houses the phased PZT impingers and all sensors. It drives by striking a consumable, external "track" (the "ice"). This keeps the complex, reusable engine separate from the simple, disposable propellant.

CONSUMABLE TRACK (External Ablative Plate)

The Dilatant Layer acts as a "mechanical clutch," stiffening under impact to focus the Stress Wave into the Ablative Layer, which vaporizes to create thrust. By scaling the impact force, we get scalable thrust from milliNewtons to Newtons, perfect for a high-speed "hockey skate."
Part 3: Spin-Off - Mechanical Reactive Armor
This is where the idea truly evolves. What if the "engine" wasn't a phased PZT array, but an incoming projectile? And what if the "bi-layer" wasn't designed for propulsion, but for *defense*?
This reframes the concept as a Mechanical Reactive Armor, designed to defeat shaped-charge jets and kinetic penetrators. It's a non-explosive, "solid-state" alternative to Explosive Reactive Armor (ERA).
Material Requirements to Surpass ERA
The goal is to use the impactor's own kinetic energy to trigger a mechanical disruption faster than ERA's chemical detonation.
- Layer 1: Strike Face (Ceramic)
- Material: Boron Carbide (B4C) or Silicon Carbide (SiC).
- Function: To shatter or blunt the projectile and transfer the shock.
- Layer 2: Mechanical "Dilatant" Layer (Cermet)
- Material: A Functionally Graded Cermet (FGM), e.g., SiC particles in a Titanium (Ti) alloy matrix.
- Function: This is the key. It's not a fluid, but a solid that *acts* like one under extreme pressure. The impact shock forces the hard SiC granules to flow laterally, creating a "shear-jamming" effect that mechanically shears the penetrator jet.
- Layer 3: Backer Plate (Ductile)
- Material: Ti-6Al-4V or similar ductile alloy.
- Function: The "anvil" that contains the energy and forces the cermet layer to flow laterally, preventing spall.
In this model, the FGM Cermet layer is the physical analogue of the dilatant fluid, using constrained granular flow to achieve the same end: focusing and redirecting energy.
Part 4: Manufacturing This "Impossible" Material
This advanced armor concept can't be built with traditional methods. The graded cermet layer requires an advanced, atom-by-atom approach. This is where PVD and Sintering come in.
A manufacturing process for a test coupon would look like this:
- Substrate Prep: Start with the Ti-6Al-4V backer plate (Layer 3).
- PVD Adhesion: Use Magnetron Sputtering (PVD) to deposit a thin (1-2 µm) pure Titanium interlayer. This "glues" the backer to the cermt.
- Graded Layering: Manually stack pre-mixed powders in a graphite die, starting with 30% SiC / 70% Ti and grading up to 90% SiC / 10% Ti.
- Strike Face Layering: Add the final layer of pure B4C powder (Layer 1) on top.
- Co-Sintering: Place the entire stack into a Spark Plasma Sintering (SPS) press. SPS uses high pressure and pulsed DC current to "pressure-cook" the entire stack (from B4C to Ti) into a single, fully dense, metallurgically bonded tile in minutes.
This PVD + SPS process is the only way to create the strong, graded interfaces this high-performance armor requires.
Conclusion: One Core, Many Applications
This refactored journey shows how a single, abstract idea—a phased traveling wave—can serve as the conceptual seed for wildly different technologies. It began as a quantum nano-drive, evolved into a macro-scale ablative thruster, and finally spun-off into a concept for next-generation mechanical armor. The physics changes, but the core principle of phased, directional energy transfer endures.
