Notatus Architecture Fundamentals

The Motor Notatus it is an alternative propulsion and electromechanical generation system based on volumetric hydraulic confinement and variable geometry. Unlike traditional combustion engines—where the reactive fluid thermally degrades in each cycle—the system operates with an incompressible hydraulic medium in a closed, highly reusable circuit.

Physical Principle and Volumetric Savings

Based on the Pascal's Principle (F = P · A), the motive force of a cylinder depends exclusively on the effective thrust surface of its base, regardless of the total volume of the containing enclosure.

Through a conified telescopic architecture and a double-piston system, the Notatus Engine implements four coordinated volume reduction methods which minimise the injection of new external fluid:

1. Dynamic Conic Geometry: As the set of concentric telescopic segments unfolds, the enclosure takes on a conical shape. Geometrically, the volume of a right-angled cone is equal to one-third of the volume of a cylinder with the same base and pitch, thereby reducing the fluid requirement from the outset to 33.3% for the same thrust.
2. Edge Void Retention: The stepped and sloped design of the internal walls of the segments generates perimeter chambers that permanently retain a fraction of liquid in the folded phase, preventing its evacuation and adding it to the next cycle.
3. Hydraulic Column and Upper Fixed Ram: A plunger fixed to the upper frame acts as a passive volumetric displacer, guiding a column of remaining fluid that prevents this space from having to be occupied by new outside fluid.
4. Lower Emerging Plunger Mechanism: A solid plunger integral with the moving cylinder head dynamically penetrates the conical cavity as it ascends. Its forced intrusion redistributes the available fluid without altering the hydrostatic thrust surface or demanding additional flow from the pump.

Volumetric Balance Equation

The synergistic combination of the four methods reduces the net volume that the external source must supply (V_tiny) to the resulting differential:

V_tiny = ΔV_enclosure − (ΔV_cone + V_perimeter + V_column + ΔV_emerging)

This configuration raises the global volumetric confinement coefficient to η ≈ 0.932, requiring only the provision of a 8.41 TP3T of fresh fluid per cycle compared to an equivalent conventional cylinder.

Amplification Factor and Empirical Validation

Flow Rate Reduction Factor (K = 9.16): The power demand of the feed pump is reduced by a factor of 9.16, allowing the energetic feasibility of mechanical feedback loops.
Technology Readiness Level (TRL 5): Experimentally validated test-bench architecture featuring a closed loop and a fast-response hydropneumatic accumulator for startup transients.

Asymptotic Theoretical Limit and Continuous Optimisation

Dynamic sizing of the emergent plunger paves the way for approximating the volumetric confinement coefficient to the intrinsic elastic limit of the transmitting medium. As the volume displaced by the plunger intrusion approaches the remainder of the cavity, the net external injection required (V_tiny) stops depending on the kinematic displacement volume and converges towards the hydraulic fluid bulk modulus β, limiting consumption exclusively to the compensation of elastic variation under high pressure and to interfacial seal renewal.
