Architectural Layers & Protocol Stacks

  • Embedded Optical Strain Sensing (Fiber Bragg Grating (FBG) / Wavelength Division Multiplexing / Optical Time-Domain Reflectometry): High-frequency optical interrogation of Fiber Bragg Grating (FBG) sensors woven into primary composite spars measuring micro-strain at 500 Hz.
  • Reduced-Order Finite Element Solving (Proper Orthogonal Decomposition (POD) / High-Speed Structural FEM Solvers): Real-time GPU execution of non-linear finite element structural equations calculating localized stress concentrations across the entire airframe.
  • Aeroelastic Gust Load Alleviation Loop (H-Infinity Optimal Control / Fast Aeroelastic Feedback Loop): Synthesizing feedforward aileron and spoiler deflection commands to counter asymmetric gust loads, reducing wing root bending moments by 22%.
  • Digital Airworthiness Dossier & MRO Integration (ATA Spec 2000 XML / Blockchain Maintenance Ledger / Cryptographic Audit Vault): Automated generation of ATA Spec 2000 compliant maintenance records and continuous remaining useful life (RUL) predictions per component serial number.

Flight Telemetry Metrics: < 2 ms (Optical Strain Telemetry Latency) | 22% (Wing Root Bending Moment Reduction) | 100% (FAA Part 21 Digital Twin Traceability) | 0.1 mm (Sub-Surface Micro-Crack Resolution)

定期点検から継続的構造健全性モニタリングへの移行

Traditional aircraft maintenance relies on conservative flight-hour thresholds and manual visual inspections. AircraftTwins integrates thousands of fiber-optic strain sensors into carbon fiber wing spars and fuselage ribs, feeding continuous load histories into high-fidelity finite element digital twins.
