Solar plane, 1st of its kind, Airbus-sized, around the world without fuel & with zero emissions: prototype runway debut

Solar Impulse solar plane, and its founders / pilots Bertrand Piccard and André Borschberg

(quote)

The prototype of a solar-powered plane, the size of an Airbus and the weight of a mid-sized car, destined for a record round-the-world journey has made its 1st trip across a runway. The plane covered at least 2km at speeds of up to 5 knots on the landing strip in Switzerland. This test run saw the Solar Impulse plane outside its hangar for the first time, with tests of its motors and computer. As wide as a jumbo jet but weighing just 1,500 kg, the plane's maiden flight is scheduled for February in 2010, and a final version will attempt to cross the Atlantic in 2012. HB-SIA’s mission is to demonstrate the feasibility of a night flight making sole use of solar energy. It is a “no frills” plane built solely for verifying our technological choices. It is a true “flying lab”. The results gained from it will be used for optimizing the construction of the HB-SIB, whose mission it will be to fly around the world without fuel and with zero emissions as from 2012.

Solar Impulse HB-SIA prototype: plane made of carbon fiber, on-board computing system helps minimize energy consumption, gondolas (x4) contain motor and batteries for storing power; wingspan: 61m, weight: 1500kg, max altitude: 8500m, speed: 70km/h read more »
