The second generation solar-powered aircraft to fly China next year

Over 6000 chemical components using innovative materials and technologies the world's largest solar-powered aircraft, the second generation of Solar Impulse (No. Solar Impulse 2) by driving two Swiss explorer arrived in China in March next year. Michelin will be over on November 11 to 14 in Chengdu, Gordon Challenge held a news conference during the Solvay company, senior vice president of the Solvay company, Solar Impulse co total charge ClaudeMichel announced the news.


ClaudeMichel said Solar Impulse solar-powered aircraft on the 2nd departure from the Gulf region, the Arabian Sea, India, Burma into China after the first stop to stay in Chongqing, and then to Nanjing. Nanjing stay a week later, across the Pacific to the United States, and finally back to the end of Europe, completed the first flight around the world.

He told China Chemical Industry News exclusive interview revealed that this aircraft wingspan as big as Airbus, as heavy as a car, motorcycle power as a small plane can fly day and night solar airplane truly no consumption, no emissions, no pollution. The aircraft in four areas, more than 6000 members Solvay's innovative use of materials and techniques.

In terms of lightweight, high-performance polyurethane foam tip spar using high-performance honeycomb composite materials, dashboard shell, fasteners and hardware, brackets shock group, throttle box assembly, cylinder, LED lamp cup etc. achieve a metal replacement. In power system efficiency, the propeller bearing grease has excellent chemical and thermal resistance to withstand temperatures ranging from -80 ℃ to 250 ℃, viscosity stability, long life, compatible with metals and plastics. In electrification, before obtaining solar photovoltaic panels, backplanes are used fluorinated film materials, solar panels assembled without delamination can withstand high and low temperature stress. In terms of energy storage, visor replace conventional adhesives can improve the specific energy of at least 10% of static and dynamic longer battery life, using the new lithium battery electrolyte stability and the energy density of the battery performance improved, the same weight of the electrolyte will Solar Impulse battery energy density increased to 260Wh / kg. The cockpit fairing, engine compartment insulation measures are used in high-performance thermal insulation polyurethane foam.

When people are discussing Beijing APEC Blue can continue going down, the Michelin Challenge Bibendum renowned experts focused on global sustainable transport sector, to discuss how to make cars per kilometer of carbon emissions to 50 grams or less. ClaudeMichel said Solvay for weight reduction on the 2nd sun power, electrification, power system efficiency, green and clean four aspects of innovative technologies, materials and solutions in the field of sustainable transport applications, can reduce vehicle weight, extend the life of lithium battery electric vehicles and improve performance, reduce fuel consumption and carbon dioxide emissions.
