Visual Crack Inspection
Periodic Visual + Eddy-Current Crack Inspection
Periodic Visual and Eddy-Current Crack Inspection is an automated non-destructive evaluation software protocol within the Lunar Ark structural health monitoring system that coordinates the L3-ROB-INSP inspection robot. Consuming one watt of operational power, the system executes four inspections per month on a periodic schedule or upon acoustic emission triggers, using machine-learning-augmented defect classification to provide ground-truth structural verification. Sustaining structural integrity across a 100-year design lifetime is complicated by vacuum exposure and 300 K thermal swings that drive cyclic fatigue, requiring authenticated visual and electromagnetic crack detection to independently confirm acoustic anomalies over a 500,000-hour mean time between failures.
