A portable cyber-physical phased-array ultrasonic system for in-situ wind-turbine blade inspection is presented. The prototype supports single scan acquisition and volumetric reconstructions via delay-and-sum beamforming with depth-dependent apodization, enabling real-time field operation on embedded hardware. The algorithmic pipeline combines dynamic receive aperture control, envelope detection, and lightweight post-filtering to provide metrologically reliable reconstructions suitable for automated re-porting and integration with digital workflows. Quantitative validation on 256 frames yields PSNR = 32.0–33.6 dB and SSIM = 0.867–0.908, confirming high reconstruction fidelity and stable acquisition required for robust volumetric sizing. Beyond imaging quality, a concise techno-economic model is used to quantify operations-and-maintenance impact under representative wholesale prices and capacity factors. Environmental and safety aspects align with these operational gains: compared with radiography, ultrasonic testing eliminates ionizing-radiation exposure, relative to penetrant or magnetic particle testing it reduces consumables and energy-efficient embedded processing with digital reporting keeps the device-level footprint secondary to the dominant benefits above.
