A SYMBOL UNDER CONSTRUCTION…
 |
After four years of research, studies, calculations and simulations, the Solar Impulse project has entered a concrete phase with the construction of an initial prototype with a 63-metre wingspan, referred to by its registration number “HB-SIA”. Its mission is to verify the working hypotheses in practice and to validate the selected construction technologies and procedures. If the results are conclusive, it could make a 36-hour flight - the equivalent of a complete day-night-day cycle - in 2010 without any fuel. |
