In an aviation first, Japan Airlines (JAL), in partnership with the Japan Aerospace Exploration Agency (JAXA) and O-Well Corporation, has unveiled a revolutionary advancement in aircraft technology. A riblet-shaped coating has been applied to most of the fuselage of a Boeing 787-9 (registration JA868J), making it the first of its kind globally.
This cutting-edge riblet coating is engineered to minimize aerodynamic drag, improving fuel efficiency and supporting sustainable aviation efforts. The aircraft is poised to break new ground as the first riblet-coated plane to enter service on international routes, with its inaugural flight scheduled for mid-January 2025.
This collaboration between JAL, JAXA, and O-Well Corporation underscores a shared commitment to reducing the environmental impact of air travel while enhancing operational efficiency. With this landmark achievement, Japan Airlines leads the charge toward greener skies, setting a new benchmark for innovation in the global aviation industry.
JAL, JAXA, and O-Well Advance Aviation Decarbonization with Innovative Riblet Coating Technology
Japan Airlines (JAL), the Japan Aerospace Exploration Agency (JAXA), and O-Well Corporation are collaborating to drive the decarbonization of the aviation industry. As part of this effort, they have applied an advanced riblet-shaped coating to an aircraft’s exterior using the innovative Paint-to-Paint Method. This technology, continuously refined by O-Well and JAXA, enhances durability while improving fuel efficiency.
Testing and Advancements in Riblet Technology
The journey toward this milestone began in July 2022, with JAL testing the durability of the riblet coating on its domestic Boeing 737-800 aircraft. In November 2023, the technology progressed to a large-scale application on the lower fuselage, where its fuel efficiency benefits were assessed. Unlike traditional decal or film-based riblet processing, the Paint-to-Paint Method integrates riblet shapes directly into the paint film, reducing weight and improving durability.
Extensive wind tunnel tests and numerical simulations conducted by JAXA confirmed the drag reduction effects on international aircraft, such as the Boeing 787-9. O-Well’s development of a riblet coating system suitable for larger aircraft has enabled the application to extend to the upper fuselage, further enhancing fuel efficiency during long-haul international flights.
Tangible Benefits for Long-Haul Operations
With the newly applied riblet coating, drag reduction during cruising is measured at 0.24%. This translates to an annual saving of approximately 119 tons of fuel and a reduction of 381 tons of CO2 emissions. To put this into perspective, the carbon savings are equivalent to the annual CO2 absorption of roughly 27,000 cedar trees.
A Commitment to a Sustainable Future
Looking ahead, JAL, JAXA, and O-Well will continue their collaboration to validate the riblet coating’s performance in terms of durability, aesthetics, and fuel efficiency on long-haul international routes. They also plan to expand the scope of the technology’s application, paving the way for greater sustainability in the aviation industry.
Through innovation and partnership, this initiative underscores the commitment of JAL, JAXA, and O-Well to reducing the environmental impact of air travel while driving advancements in green aviation technologies.
