As efforts toward decarbonization progress in the aviation industry, demonstration experiments have begun in Japan to reduce air resistance and reduce fuel consumption by making the surface of aircraft a so-called "shark skin".
All Nippon Airways will start the demonstration test on flights connecting Haneda and Europe and the United States from the 5th, and the so-called "shark skin" film with fine unevenness is attached to two places on the surface of the aircraft on a few dozen centimeters square. To do.
According to All Nippon Airways, the unevenness of about 1/100th of a millimeter reduces the air contact area and reduces resistance, and it has already been introduced in some parts of Germany.
All Nippon Airways estimates that 124,000 liters of fuel per year, or about 2,600 25-meter swimming pools, can be saved if 80% of the surface of all of the aircraft it owns is covered with film. We will consider the possibility of introducing it.
The domestic aviation industry has set the goal of achieving "carbon neutrality" by reducing greenhouse gas emissions to virtually zero by 2050, and each company is making efforts to decarbonize the industry.
Mr. Kojiro Matsui of the All Nippon Airways Maintenance Center said, "The reduction of carbon dioxide is a major issue imposed on airlines, so we would like to promote efforts to contribute."
