Inspection Drone

Inspection Drone from South Korea, produced by The Korean Air Aerospace

Introduce:

Korean Air’s aircraft inspection technology is the first in the world to deploy multiple drones simultaneously, shortening maintenance time and dramatically increasing operational stability.

The airline has developed a drone with a one-meter width and height, weighing 5.5 kg. The aircraft fuselage can be inspected using four of these drones simultaneously. The company has also developed an operations program that allows the four drones to be programmed to take photos of pre-planned areas. If one of the drones fails to operate, the system is configured to automatically complete the mission using the remaining drones.

When four drones are operated simultaneously, the usual visual inspection time of about 10 hours can be reduced to about four hours, a 60 percent decrease in time, and this will help to improve on-time flight operations. Moreover, the drones, which are equipped with high-performance cameras, can identify objects up to 1 mm in size, allowing for detection of micro defects that cannot be seen from above with the naked eye.

Korean Air shares inspection data through the cloud, enabling employees to easily check inspection results anywhere and anytime. The airline has also applied a collision avoidance system and geo-fencing to maintain safety distances from surrounding facilities and prevent break-aways from the mission area.

In addition to developing this new technology in line with the government’s policy to strengthen the competitiveness of the aircraft MRO industry, the airline has also revised regulations to improve drone maintenance procedures such as requiring the presence of safety personnel in addition to pilots and engineers.

Korean Air will work to improve safety and convenience for workers, stabilize operations and increase accuracy of inspections through continuous trials before officially launching the inspection drones next year.
