Detectable Inspection: Propeller Nick Detection Model Development Using YOLOv8

open access: yesInternational Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
Purpose: Nicks in the propeller can lead to catastrophic failures if not repaired properly, but proper detection can be difficult. To improve nick inspection tasks, the researchers intend to develop a nick detection model using the object detection algorithm, You Only Look Once. Design/Methodology/Approach: The researchers select YOLOv8 algorithm.
