The Swiss solar-powered plane Solar Impulse 2 (Si2) took off from the UAE Monday,starting its five-month record-breaking round-the-world flight. In due course the planewill touch down in Chongqing and Nanjing.
The Si2 is powered by 17,247 solar cells stretched across the plane's wings which exceedthe span of a Boeing 747. Lithium batteries will help store energy, allowing the aircraft tofly at night.
China is well to the fore in this field. The China Academy of Aerospace Aerodynamics hasbeen quick to achieve fruitful results in height gain and endurance of its solar-poweredUAV.
Developed by China Academy of Aerospace Aerodynamics, China’s own solar UAV is theworld's largest unmanned solar aircraft, with a wingspan of more than 40 meters and alightweight structure with large aspect ratio.
Traditional aircraft using chemical fuel cause severe pollution to the atmosphere. Thesolar-powered UAV, a real green and environmental-friendly aircraft, has prospects forextensive applications.
