World’s first solar powered aircraft on global journey- Solar Impulse 2 successfully landed in Ahmedabad, Gujarat.

The aircraft was piloted by Swiss pilots Bertrand Piccard and Andre Borschberg from its first halt Muscat, Oman.

Key features of Solar Impulse 2 aircraft

  • It is a Swiss long-range solar-powered aircraft project and claimed to be first aircraft to fly day and night without consuming conventional fuel.
  • Solely propelled by the solar energy and emits zero Carbon Dioxide (CO2).
  • Structure: Single-seater aircraft made of carbon fibre. It has a 72 metre wingspan and weighs 2,300 kilo grams.
  • Solar cells: 17,248 solar cells inbuilt into its wings. These cells supply renewable energy to propel the electric motors of aircraft.
  • These solar cells also recharge 4 lithium polymer batteries mounted on aircraft which allows it fly at night.

The first test flight of the aircraft was conducted in the United States in 2013.

Solar Impulse’s maiden global journey
