Riblets reduce skin friction drag, cut CO2 emissions, and advance environmentally friendly aviation technology.

Riblet technology with shark-like longitudinal grooves on the surface of the aircraft

JAXA is conducting research and development of riblet technology to improve the environmental performance of aircraft. Riblet technology involves applying fine longitudinal grooves to the aircraft’s surface to reduce aerodynamic drag. These grooves decrease the surface area exposed to fast airflow, thereby reducing surface skin friction drag and fuel consumption.

Practical application of riblets to reduce environmental footprint

JAXA is collaborating with Japan Airlines, O-well, and Nikon to develop this technology through flight tests, wind tunnel tests, and numerical simulations. The implementation of riblet technology in commercial aircraft is expected to improve fuel efficiency and reduce CO2 emissions.　JAXA will continue to promote social implementation of its research and development results and contribute to the advancement of environmentally friendly aviation technology.
