Aereo solare tenta il primo volo notturno

Le condizioni meteorologiche sono favorevoli per 'Solar Impulse'

GINEVRA - L'aereo solare svizzero Solar Impulse dovrebbe tentare il primo volo notturno il prossimo primo luglio. Lo hanno affermato oggi i promotori dell'iniziativa.

Le condizioni meteorologiche sono favorevoli e ''le propabilita' di vedere l'aereo a energia solare HB-SIA decollare il primo luglio ed atterrare il mattino del 2 luglio sono sempre piu' grandi'', afferma una nota pubblicata oggi a Payerne (Svizzera occidentale) da Solar Impulse. La sfida sara' di mantenersi in volo un'intera notte solo grazie all'energia solare accumulata. La conferma definitiva del tentativo e' prevista 24 ore prima.

Secondo i piani, il velivolo dovrebbe decollare dalla base di Payerne verso le ore otto del mattino e cominciare un'ascensione che durera' tutto il giorno, fino ad un'altitudine di 9.000 metri. Durante l'ascensione l'aereo dovra' immagazzinare la massima quantita' di energia nelle sue batterie. Quando i raggi del sole diminuiranno di intensita', l'HB-SIA comincera' a scendere fino a 1.500 metri. Dopo il tramonto continuera' poi a volare, con l'energia immagazzinata fino al ritorno del sole il mattino dopo.

L'interrogativo e' di ''sapere se il pilota potra' economizzare abbastanza energia per volare l'intera notte'', sottolinea la nota di Solar Impulse. L'impresa potra' essere seguito in diretta su Internet.

Il velivolo a propulsione solare Solar-Impulse HB-SIA e' un 'uccello' con un'apertura alare pari a quella di un Airbus A340 (63,4 metri) ed un peso di 1.600 Kg, pari a quello di un'automobile. Ha compiuto il suo primo volo in altitudine con successo il 7 aprile scorso. Il volo era durato 87 minuti. Da allora altri voli di collaudo sono stati effettuati.

Obiettivo finale sara' di compiere il giro del mondo a bordo del primo aereo solare in grado di volare di giorno e di notte, senza carburante o emissioni inquinanti. Anima del progetto e' lo svizzero Bertrand Piccard. (ANSA).

Solar Impulse successfully lands in Washington D.C.

Solar Impulse has successfully completed the second-to-last leg of its Across America mission by landing at Washington Dulles International Airport (IAD) on Sunday, June 16 at 12:15 a.m. EDT. The solar-powered airplane of Swiss pioneers Bertrand Piccard and André Borschberg used an unprecedented flight strategy to arrive in Washington D.C. on time despite difficult weather conditions characterizing the cross-country flights.

The fourth leg has been split into two flights because strong cross and head winds would slow down the aircraft and made it impossible for the pilot to reach the nation’s capital within 24 hours, which is the limit set for the pilot in the cramped single-seater cockpit. The flight plan was modified as follows: André Borschberg first took off on Friday, June 14 from Lambert-St. Louis International Airport and flew the aircraft for the first half of the leg until Cincinnati Municipal Lunken Airport. After a short pit stop of 14 hours, fellow pilot Bertrand Piccard took over the plane’s controls and flew the second half of the flight, landing at Washington Dulles International Airport Sunday, June 16 shortly after midnight.

“To land in the Capital of the United States has a dual significance for me: On the one hand, it proves the reliability and potential of clean technologies and this is crucial in pushing our message forward,” explained Bertrand Piccard upon exiting the airplane. “On the other hand, to be hosted by the Smithsonian Institution is an honor for Solar Impulse. The capsule of my around-the-world balloon flight is already displayed in the Air and Space Museum and I hope one day a second Swiss aircraft will join the collection…” he added while glancing at Solar Impulse.

After Bertrand Piccard’s landing at Dulles, André Borschberg added that “with the successful completion of these last four US flights, we have shown that we are capable of coping with challenging meteorological conditions for our weather-sensitive plane and for our ground operations, and that we could find each time the right solutions to move forward. It has been a succession of fruitful learnings preparing us for the 2015 world tour.”

On Monday, the Secretary of Energy Ernest Moniz will greet the Solar Impulse crew during an energy roundtable and press conference, while the aircraft will be on display on Sunday, June 16 from 1:00 pm to 5:00 pm outside the Smithsonian National Air and Space Museum’s Steven F. Udvar-Hazy Center. Solar Impulse will present Clean Generation, its latest initiative for the global adoption of clean technologies to key decision makers. Clean Generation is a global movement supported by thousands of people and more names are added at every stopover onto a USB stick and symbolically carried in the cockpit of the airplane as virtual passengers.

SOLAR IMPULSE WASHINGTON D.C. SCHEDULE
Solar Impulse Open House outside the Udvar-Hazy Center: Public Visits will be organized on Sunday, June 16 from 1.00 p.m. until 5 p.m. The public can enter through the building's main entrance and will be directed to the door leading outside the Space Hangar to the aircraft's tented display area.
Roundtable and press conference with Secretary of Energy Ernest Moniz as special guest on Monday, June 17 at noon.
Several private Solar Impulse partners events throughout the week of June 17 – 23.
The last challenge for Solar Impulse will be to reach New York by early July. André Borschberg will fly the final leg of the Across America journey from Washington Dulles International Airport to JFK in New York. The departure date will depend on weather conditions.

The Solar Impulse Across America mission is made in partnership with Solvay, Schindler, Bayer Material Science, Swiss Re Corporate Solutions, Sunpower and the Swiss Confederation.
