In order to further reduce fuel expenditure and reduce costs, the second largest discount airline in Europe, EasyJet Airline Company Limited, announced that it will experiment with a new nano-coating on some of its aircraft to determine the coating The role in reducing fuel consumption. The company is said to be the first commercial airline in the UK to adopt this high-tech fuselage coating.

Ultra-light ultra-thin "nano clothing"

According to researchers, this coating can be described as both light and thin, which can minimize the increase in the weight of the aircraft. It is almost negligible in weight-the weight added to the fuselage after processing a medium-sized passenger aircraft is only 4 ounces (about 113 grams), and its thickness is 100 times thinner than the average diameter of human hair.

The researchers said that this ultra-thin film technology will make the fuselage more aerodynamic, and the smoother surface can greatly reduce the friction between the fuselage and the air during the flight of the aircraft, thereby reducing fuel costs. Airlines provide more space for ticket discounts.

The effect is like coating a rough concrete wall with paint. This coating smoothes out the slight depressions and protrusions that can only be observed with a microscope on the body. The surface of the fuselage processed by this technology will be smoother than before and have better aerodynamic performance, thereby reducing fuel consumption.

The principle of the entire aircraft painting process is somewhat similar to makeup. First of all, the surface of the fuselage should be thoroughly cleaned to remove dirt located in the recesses on the surface of the fuselage or even invisible to the naked eye, and then a positive charge is applied to the fuselage so that the ultra-thin nano-coating with negative charge can Closely integrated with the body, like a foundation, the entire surface of the body is smooth, smooth and flawless. In addition, since the coating contains acrylic elements with high strength and durability, this coating also has good strength and can form a barrier on the surface of the fuselage to prevent the penetration of dirt and debris.

It is understood that apart from British Express Airways, this technology has already been tried on US Air Force aircraft, and this is the first time it has been applied to British commercial airlines.

Fuel saving and air saving

The researchers said that this new coating can effectively reduce the fuel consumption of each flight by 1%-2%, thus reducing the cost of airlines by at least 20 million pounds per year. Last year, British Express Airways spent nearly 750 million pounds on fuel costs, and with the continuous rise in international crude oil prices, this year may reach 1 billion pounds.

It is understood that there are currently 194 passenger jets on EasyJet, carrying more than 50 million passengers annually. The first batch of 8 aircraft will be coated with this coating, and within a period of 12 months, the effectiveness of this technology will be verified by comparison with other aircraft not coated with this coating. If its energy-saving effect is confirmed, the company will apply this coating to all of its aircraft.

Caroline McCall, President of EasyJet said that this technology will not only reduce the operating costs of airlines, but also make people buy cheaper air tickets, and at the same time reduce the number of people travelling by plane. Carbon footprint.

Founded in 1995, British Express Airways is the second largest discount airline in Europe, second only to Ryanair. It specializes in short- and medium-distance transportation. It is headquartered in Luton Airport, London, United Kingdom. The company advocates low prices and conciseness, does not provide unnecessary services, sells tickets directly without agents, and does not provide free meals on board. For the twelve months ended September 30, 2010, the company's after-tax profit reached £ 121.3 million (approximately US $ 188.7 million).
