Korean Air Delivers First Boeing 737 MAX Winglet

Korean Air has delivered its first Boeing 737 MAX winglet.

The winglet, featuring a split tip, will be installed on B737 MAX’s three-meter long wings which can play a role to increase the wing length, reduce resistance, and improve fuel efficiency by 1.5%.

Following this first B737 MAX winglet delivery, Korean Air will supply around 2,400 units of B737 MAX winglets over the next few years.

The production of B737 MAX Advanced Technology Winglets requires various cutting-edge technologies, such as fabrication technique for Co-cured Blades, ultraprecision machining system and non-destructive inspection.

The company set up a task force comprising of specialists to take charge of the project and perform various tests, ensuring the maturity of technologies and identifying solutions to different problems.

Korean Air has played a major role in components manufacturing for both Boeing and Airbus. The airline has participated in development of B787’s major components, including the composite rear fuselage of the aircraft and the raked wing tips. Furthermore, Korean Air demonstrated its manufacturing ability of complex composite aerostructures by producing cargo doors for the A350 and Sharklets for the A320.
