我不知道有沒有太陽能飛機 我找找看好厲害喔 謝謝Solar Impulse is a Swiss long-range experimental solar-powered aircraft project, and also the name of the project's two operational aircraft.The privately financed project is led by Swiss engineer and businessman André Borschberg and Swiss psychiatrist and balloonist Bertrand Piccard, who co-piloted Breitling Orbiter 3, the first balloon to circle the world non-stop.[2] The Solar Impulseproject's goals were to make the first circumnavigation of the Earth by a piloted fixed-wing aircraft using only solar power and to bring attention toclean technologies.[3]Solar Impulse 1 landing at Brussels Airport afterits first international flight on 13 May 2011General informationTypeExperimental solar-powered aircraftNational originSwitzerlandManufacturerSolar ImpulsePrimary userAndré Borschberg and Bertrand PiccardNumber built2 (including prototype)HistoryManufactured2009–presentFirst flight3 December 2009The aircraft is a single-seated monoplane poweredby photovoltaic cells; it is capable of taking offunder its own power. The prototype, often referred to as Solar Impulse 1, was designed to remain airborne up to 36 hours.[4] It conducted its first test flight in December 2009. In July 2010, it flewan entire diurnal solar cycle, including nearly nine hours of night flying, in a 26-hour flight.[5]Piccard and Borschberg completed successful solar-powered flights from Switzerland to Spain and then Morocco in 2012,[6] and conducted a multi-stageflight across the US in 2013.[7][8]A second aircraft, completed in 2014 and named Solar Impulse 2, carries more solar cells and more powerful motors, among other improvements. On 9 March 2015, Piccard and Borschberg began to circumnavigate the globe with Solar Impulse 2, departing from Abu Dhabi in the United Arab Emirates.[9] The aircraft was scheduled to return to Abu Dhabi in August 2015 after a multi-stage journey around the world.[10] By June 2015, the plane had traversed Asia,[11] and in July 2015, it completed the longestleg of its journey, from Japan to Hawaii.[12] During that leg, the aircraft's batteries sustained thermal damage and took months to replace.[13]A battery cooling system was installed and Solar Impulse 2 resumed the circumnavigation in April 2016, when it flew on to California.[14][15] It continued across the US until it reached New York Cityin June 2016.[16] Later that month, the aircraft crossed the Atlantic Ocean to Seville, Spain.[17] It stopped in Egypt before returning to Abu Dhabi on 26 July 2016, more than 16 months after it had left (506 days), completing the approximately 42,000 km (26,000 mi) first circumnavigation of the Earth by a piloted fixed-wing aircraft using only solar power.[18][19]In 2019, the Solar Impulse 2 was sold to Skydweller Aero, a US-Spanish company using the airframe todevelop autonomous unmanned aerial vehicles capable of perpetual flight.[20] It plans to use the aircraft for research and development and flight testing, after which the Solar Impulse 2 will be returned for permanent display at the Swiss Museum ofTransport.感謝您分享知識 謝謝太感人了 影片可以去youtube看謝謝您^謝謝IQE QICQ大大
