Architectural Layers & Protocol Stacks

• In-Flight Structural Sensor Ingestion (Fiber Bragg Grating (FBG) Optical Interrogators): Measuring micro-strain deflections and thermal gradients along composite wing spars at 500 Hz.
• Real-Time Reduced-Order Physics Solver (Finite Element Analysis (FEA) Reduced-Order Models): Calculating structural stress distribution across the entire airframe within milliseconds of flight maneuvers.
• Cumulative Structural Damage & Fatigue (Linear Elastic Fracture Mechanics / Paris' Law): Tracking micro-crack formation, fastener hole fatigue, and composite delamination over millions of flight cycles.
• Maintenance Operations & Fleet Lifecycle (Automated Non-Destructive Inspection (NDI) Dispatch): Directing maintenance inspectors to exact fastener rows requiring ultrasonic scanning prior to heavy C/D checks.
