Nikon has introduced its groundbreaking riblet-processing technology, inspired by the unique surface structure of shark skin, to enhance efficiency in aviation, wind, and water power sectors. This innovation, based on Nikon’s advanced laser processing capabilities, aims to reduce drag and improve fuel consumption.
How Nikon Riblet Processing Works
The riblet technology uses precisely engineered grooves, applied to aircraft surfaces such as wings and fuselages, to minimize air resistance. This design mimics the natural longitudinal grooves of shark skin, allowing for smoother airflow. Nikon predicts this advancement could cut aircraft fuel costs by ¥8 billion annually (approximately $51 million) and reduce carbon emissions by 300 tons each year.
First implemented in 2019, the technology has shown promise across multiple industries. Recently showcased at CES, Nikon highlighted its successful application on wind turbines and its use by major airlines like ANA and Japan Airlines. The company is now exploring its potential for helicopter blades to further improve efficiency.
Shark skin’s evolutionary design, honed over 400 million years, inspired Nikon’s riblet technology. By leveraging expertise in laser machining, Nikon creates durable, heat-resistant microstructures on materials like metals, films, and resins, achieving up to a 7% reduction in friction. Unlike traditional resin-based methods, Nikon’s laser etching ensures precise application on curved surfaces, eliminating common issues like wrinkles or peeling.
Despite initial challenges, such as slow laser processing speeds and pandemic-related delays, Nikon has made significant strides. “Scaling up production remains a focus,” noted Mutsuki Nakayama, a Nikon representative. The company continues refining its processes to meet rising demand.
Nikon Riblet Processing stands as a testament to how biomimicry and advanced engineering can drive sustainability in aviation and beyond, paving the way for a carbon-neutral future.
