Detectable Inspection: Propeller Nick Detection Model Development Using YOLOv8

International 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.

The Spirit of the Service: Dash, Discipline, and Flying Accidents in the Royal Australian Air Force, 1921–48

Australian Journal of Politics &History, Volume 70, Issue 4, Page 658-682, December 2024.
From its establishment in 1921, the Royal Australian Air Force (RAAF) attracted political and public critique for flying accidents. This article explores how its nascent institutional ethos developed in relation to a problematic safety record. Military aviators were expected to balance airborne “dash” against obeying flying orders, risking castigation ...
