Solar Impulse on First Leg of Epic Tour

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Solar Impulse 2, under the control of André Borschberg, took off at 7:12 a. m. (03:12 UTC) Abu Dhabi time, on the first leg of its around-the-world voyage.  The roughly 400 kilometers (215 nautical miles) between Abu Dhabi and Muscat, Oman – the airplane’s first stop – takes less than an hour by airliner and around five hours (according to Google Maps) by Maybach or lesser motor vehicle.  It took André nine hours, one minute for this leg, traveling at ultralight speeds.  His landing was tweeted as looking like a UFO descending, LED landing lights ablaze and advancing slowly overhead.  In the control room, Bertrand Piccard and His Serene Highness Prince Albert II of Monaco followed the flight with advice and encouragement.  His Highness helps promote aviation ventures which show promise for cleaning the atmosphere, including record attempts by Jean-Luc Soullier in his electric aircraft.

Solar Impulse 2 – The Bikes Chasing the Airplane

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Solar Impulse 2, now preparing for its imminent attempt at an around-the-world voyage, has made three flights in Abu Dhabi, one maintenance test to check operation of the huge craft, and one training flight each for the adventure’s pilots, Andre’ Borschberg and Bertrand Piccard. In almost every video of HB-SIB’s takeoffs and landings, two or three cyclists can be seen chasing the Solar Impulse, causing one curious viewer to ask EV World what kind of bikes they are.  Of course, they are electrically-enhanced, fitting the project, and Swiss, part of Solar Impulse’s national pride. The Stromer bicycle is an advanced machine, with a rear wheel-hub motor, removable battery pack, and connectivity through a smart phone interface.  There is some conflict between the guesstimate of which model the Solar Impulse team uses by EV World’s editor, who is himself involved with electric bicycle sales, and the specifications set forth by Stromer. EV World’s editor shared the following.  “I soon learned the …

Solar Impulse 2 in Readiness for Around-the-World Flight

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Reassembled and ready, Solar Impulse 2 stands ready to leave Abu Dhabi on an historic around-the-world flight within the next month, according to the project’s latest announcements.  When HB-SIB leaves Abu Dhabi, it will cross two oceans and four continents before returning to its departure point.  The trip will include landings in 12 locations and a total distance of 35,000 kilometers (21,700 miles) – all without using a drop of fuel. Its route and schedule will be affected by weather, and since the airplane will fly at only 27 miles per hour at night to conserve battery energy, by prevailing winds.  Normal flight speeds will range from 50 to 100 kilometers per hour (31 to 62 mph). The press release lists the landing sites: “Si2 will take-off from Abu Dhabi, capital of the United Arab Emirates, in late February or early March and return by late July or early August 2015. The route includes stops in Muscat, Oman; Ahmedabad and …

A Big Plane Swallows a Bigger Airplane, Flies it to Abu Dhabi

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Solar Impulse 2 is a big airplane, with a wingspan greater than that of the Boeing Cargolux carrier that transported it to Abu Dhabi this last weekend.  Seeing the craft slipped into the cargo hold of the whale-like Boeing, then disgorged a few hours later, presents an almost mythical vision of leviathans at work and play. Abu Dhabi, the capital city of the United Arab Emirates, has been named the Host City of Solar Impulse for the first round-the-world solar flight, to be started 50 days from now in March.  Following over a score of test flights in Switzerland, HB-SIB was dismantled and packed aboard the 747 that would carry it to the UAE, where it will be prepared for its epic journey.  The mission was announced last year in New York at the UAE reception “on the sidelines of” that United Nations General Assembly.  Attendees included Swiss, UAE and UN dignitaries along with officials “from over 50 countries represented …

Solar Impulse Wrapping Up Flight Tests before Heading to Abu Dhabi

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Solar Impulse 2, HB-SIB, flying now for several months, is being readied for a trip to Abu Dhabi, the capital of the United Arab Emirates and host city for Solar Impulse’s around-the-world flight.  From there, early in 2015, it will embark on its around-the-world flight, alternately flown by Bertrand Piccard and Andre’ Borschberg. The program continues the drive and immense logistical planning evidenced by Solar Impulse 1’s across-America flight last year.  “What better way to demonstrate the importance of the pioneering, innovatory spirit than by achieving ‘impossible’ things with renewable energy and highlighting new solutions for environmental problems?” This attitude will be necessary to overcome the challenges of five-day, cross-ocean flights each pilot will face, and to meet the meteorological conditions following the equator much of the way. The bigger, heavier SI2 will cross deserts, the Great Wall of China, and repeat its journey across America on its five-month circumnavigation of the globe.  Beginning in March, 2015 from Abu Dhabi, …

Solar Impulse 2 Makes Premier Flight

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Solar Impulse HB-SIB, the second aircraft from the program headed by Andre’ Borschberg and Bertrand Piccard, took to the skies early this morning piloted by Markus Scherdel.  Taking off from Payerne Airport at 3:38 Greenwich Mean Time (GMT) Solar Impulse 2 climbed to a randomly orbiting path within a 20-mile compass of the airfield to the southwest, Lake Neuchatel to the north, and Belleville to the northeast. At about 4:01 GMT, and about 5,300 feet, Scherdel reported a slight vibration and briefly leveled off until determining that it was probably an aerodynamic vibration – not a motor issue, but possibly from a hatch door.  He continued climbing and performed a bank angle test of 5° at varying airspeeds and “a steady heading sideslip” to determine that controllability and stability were OK. At 4:47 GMT the team’s web site reported, “Flight Director is quite happy: no problem has been detected on the electrical and propulsion system, stability of airplane is good.  …

72 Hours of Flight, Exercise, Rest, and Hypnosis

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

The first Solar Impulse airplane, HB-SIA, has demonstrated repeatedly that it can stay up all day and all night.  The idea of perpetual flight has enticed designers for years, but the idea of a perpetual pilot has not – until the space age.  Charles Lindbergh had a restless night before his May 20, 1927 takeoff for Europe and spent much of the 33-1/2 hour flight battling his nearly overwhelming need for sleep.  A solar-powered flight will be considerably slower, and thus longer in duration, than Lindbergh’s epic voyage, however. With planned flights for HB-SIB, the second Solar Impulse craft, anticipated to span continents and oceans, the need for maintaining pilot health and alertness becomes imperative. As the team explains, “Over the several years Solar Impulse has proved that is its possible to fly with unlimited endurance. But as we know, Solar Impulse is more than a technical challenge. It is also about pushing human limits to new levels. “The Transatlantic …

Solar Impulse Makes It to New York Early

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

It’s hard to believe that the Solar Impulse has been on its Cross America tour since May 3, but its early touchdown at New York City’s John F. Kennedy International Airport late Saturday night was cause for elation on at least two counts. First, as the Solar Impulse team points out, “For the first time a plane capable of flying day and night powered exclusively by solar energy has crossed the USA from the West to the East Coasts without using a single drop of fuel.”  As we love to point out, though, it’s not the first time a solar-powered airplane has made the trip.  Eric Raymond did it in 21 hops in 1990 in Sunseeker 1, using the technology available at the time – which did not allow overnight flights.  Both trips are literally epic voyages, nonetheless. Second, for several anxious hours the flight, the airplane and even the fate of pilot Andre’ Borschberg, Solar Impulse’s co-founder and CEO, …

What a Month This Will Have Been

With Solar Impulse descending on Washington, D. C., the Cross USA flight reached a symbolic conclusion, bringing the future to a capitol that seems resistant to even modest change, let alone radical departures from current, conventional reality. http://www.youtube.com/watch?v=n64tAJs_c8w With one hop to go in its journey, Solar Impulse has spread the message of what might be if we have the will to overcome the inertia brought about by our well-lobbied legislature. Andre Borschberg and Bertrand Piccard have one more opportunity to challenge the world to adopt green energy when Solar Impulse goes to New York City. Monday, they met with Energy Secretary Ernest Moniz, with whom they participated in an energy roundtable and news conference about the technology that made their flight possible.  Doubtless, they shared their mission’s primary object, furthering the global “Clean Generation” initiative – “a movement of likeminded people ready for change; ready for greater investment in technological innovation for a cleaner future.” As the partners explain …
