Solar plane prototype in first test flight

http://xenophilia.com/wp-content/uploads/2010/04/solar-impulse.jpgA prototype solar-powered plane has made its first full test flight – coming closer to the goal of using solar energy to fly around the world.

The Solar Impulse, with a wingspan similar to that of a super-jumbo jet but weighing the same as a saloon car, took off from a Swiss airfield.

The plane’s wings are covered by solar cells which power four electric motors.

Its designers hope a slightly larger production model will circumnavigate the globe in two years’ time.

The test flight was intended to verify that the plane’s behaviour tallied with simulations.

“With such a large and light plane never having flown before, the aircraft’s flight behaviour remains unexplored,” the flight team said in a statement.

Round-the-world balloonist Bertrand Piccard is leading the project and intends to pilot the plane along with co-founder Andre Borschberg.

“It’s a very important moment after seven years of work,” said Mr Borschberg before the take-off.

Witnesses said both take-off and landing seemed to go smoothly.

The flight team have been conducting flea-hop tests since December, taking the plane no higher than 60cm (2ft) in altitude and 300m in distance.

A night flight is planned later this year, and then a new plane will be built based on the results of those tests.

The big take-off is planned for 2012, when the two pilots will try a transatlantic flight before attempting to circumnavigate the globe.
