"G" is a unit of acceleration, where 1G equals the acceleration due to Earth's gravity (9.8 m/s²). This means that experiencing "50G of impact" means that such acceleration is applied all at once. It is a force much greater than one might imagine. For example, if you drop an object from a height of 1 meter, the falling speed is about 4.42 m/s. The impact increases with the weight of the object. If you drop a 10 kg box of oranges from just 31 cm, it experiences an impact of 50G. This calculates to a force equivalent to about 500 kg being applied instantaneously. *For more detailed information, you can view the related links.

This article introduces the current state of blade inspection and maintenance for wind power generation facilities, which have been rapidly increasing in construction in recent years, as well as the inspection methods expected for operational power generation equipment in the future. Traditionally, the main methods for inspecting blades have been visual inspections using cranes or rope access. This allowed for checking the surface and structural defects of the blades, but there were concerns about the safety of workers due to the high-altitude work. Additionally, work was often constrained by wind speed, and weather conditions such as rain and wind frequently affected operations, necessitating adjustments to inspection schedules. Furthermore, inspections required power generation to be halted each time, which posed challenges to power generation efficiency. In recent years, advancements in technology have significantly changed the methods for inspecting wind power blades. In particular, inspection techniques using drones have garnered attention. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*
