Ultra-lightweight plane to fly across USA


The so-called Solar Impulse, an ultra-lightweight, solar-powered plane, capable of flying day and night– is set to take flight across America. The plane features several material innovations and technologies from Bayer MaterialScience such as polyurethane rigid foams used in the wing tips, motor gondolas and cabin, polycarbonate films used in the cabin window and adhesive and coating raw materials used in the cabin, as well as structure-covering films and wing-covering fabric.

The plane will start its cross-country flight in San Francisco, stopping off in Phoenix and Dallas before landing in Washington, D.C., and then onto its final destination, New York City. During the day, 12,000 solar cells on the surface of the aircraft power four electric motors and charge four lithium polymer batteries, enabling the aircraft to fly with solar energy during the night.
