Supporters of the Solar Impulse gathered to celebrate the giant solar-powered airplane’s landing in Brussels, Belgium today after the craft had crossed Switzerland, France, Luxembourg, and Belgium in its 630 kilometer (340 nautical mile), 12 hour, 59 minute flight. André Borschberg, CEO and co-founder of the project, flew the mission, starting 8:30 a.m. Payerne, Switzerland time and took the leisurely flight over some of the most scenic landscapes in Europe, with an average speed of 50 kilometers per hour (27 mph – one mile per hour under the stall speed of US ultralights).  He had time to enjoy the view from his average cruising altitude of 1,828 meters (6,000 feet).  Borschberg explained, “It’s a spectacular flight. The takeoff was a little challenging because we had to rush due to air traffic activity consequently I needed a little bit of time to get everything in order before I could become serene.  It was [a] little bit [of a] northeast wind during …

To prepare Solar Impulse and its pilots for the upcoming airshow season, André Borschberg and other members of the flight team completed a series of tests to enable precise flying, particularly around the Paris Air Show at Le Bourget. “We are preparing for these trips beforehand because they are very complex operations, from both a logistical point of view and purely in terms of flying”, Borschberg explained following his three-hour flight on April 18. Solar Impulse will be the “special guest” at the Paris Air Show at Le Bourget from June 20 through 26. This last week’s tests were designed, according to acting flight test director Ralph Paul, with “two objectives…: to adopt the Bourget configuration and increase the flight envelope by doing stickraps.” As the project’s blog explains, “The solar airplane made three simulations closely modeled on the choreography to be adopted for the presentation flights in Paris…. Initially, the pilot climbed to an altitude of 1000 feet (a …

Andre’ Borschberg, CEO of the Solar Impulse project, has been flying the giant airplane over many scenic and civic sites in Switzerland, crossing from its home field at Payerne to Geneva International Airport on September 21, and then returning the same day to Payerne.  The next day, Borschberg cruised to Zurich International Airport and returned to the plane’s home base.  As quoted in the project’s press release, Borschberg was happy about the chance to view Switzerland from his rare and lofty perch.  “’These flights are just amazing! Thanks to the plane’s low speed, I was able to discover Switzerland from a completely new angle, fully taking in the beauty of our country!’ said André Borschberg, CEO and Co-founder of Solar Impulse, from the cockpit of HB SIA in Zurich. ‘The Swiss solar flights represent a major step forward for our team, taking us away from our customary airspace. We have learned to work together with international airports, merging in with …

QinetiQ Zephyr Breaks Official Record for Solar-Powered Endurance

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

According to BBC News and GlobalFlight.com, QinetiQ’s Zephyr, a 22.5 meter (72 feet) unmanned, solar-powered aircraft has been in the air for more than a week over the Yuma, Arizona Proving Grounds, and program managers intend to keep it there for a total time of at least fourteen days.  Having flown since 6:40 a.m. July 9, its endurance is now four times that of any other unmanned aerial vehicle.   A US Global Hawk holds the current official world endurance record for an unmanned aerial vehicle (UAV) of 30 hours, 24 minutes.  Zephyr’s record is being certified by the Federation Aeronautique Internationale, the world air sports federation. Jon Saltmarsh, Zephyr’s project manager, says the craft, “Is basically the first ‘eternal aircraft,’”  a name once given to AeroVironment’s Helios and related aircraft.  The 50 kilogram (110 pound) unmanned airplane emulates the flight pattern followed by Andre’ Borschberg in taking the Solar Impulse to a world record for manned solar-powered airplanes.  Its thin solar cells power the twin …

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Andre’ Borschberg, CEO and co-founder of the Solar Impulse project, landed this morning at 9:00 a.m. (local tme) in Payerne, Switzerland, having completed the first-ever night flight on battery energy stored during the previous day through the craft’s solar cells.  Taking off at 6:51 a.m. July 7, Borschberg flew the 64-meter span, four-motor airplane in large patterns around the area, gaining altitude to a height of 8,564 meters (27,404 feet) above sea level and charging the batteries – all while running the motors at climb power. As night fell, he glided to preserve the stored power, ran the motors as needed to maintain altitude, and landed with a small reserve.  This successful demonstration of being able to run the motors on solar power while still charging the batteries means the project can go on to its next stages, spelled out in this morning’s press release “The success of this first night flight by a solar-powered plane is crucial for the further …

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Its telemetry problems resolved, Solar Impulse HB-SIA took off at 6:51 a.m., Payerne, Switzerland time, July 7, for a day of collecting sunlight in its huge array of solar cells.  If Andre’ Borschberg, CEO and cofounder of the project, decides that enough electricity has coursed through the giant craft’s wings to charge the batteries sufficiently, he will attempt to keep flying through the night. The Solar Impulse Project notes the following in today’s press release.  “The whole day long, up to about 19:30 (7:30 p.m., Payerne time), the prototype will be slowly ascending to an altitude of 8,500 metres, while at the same time charging its batteries in preparation for the night flight. When the sun’s rays stop being strong enough to supply the solar cells (about two hours before sunset) with energy, the HB-SIA will start a slow descent, reaching an altitude of around 1,500 metres by 23:00. It should then carry on flying, using the energy stored in …

Solar Impulse Night Flight Postponed

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

The Solar Impulse project sent out the following press release this morning: “Dear Solar Impulse Friends, “This morning at 06h45, the Solar Impulse Mission Team had to take the difficult decision to postpone the first night flight attempt. “The problem comes from the telemetry transmitter that has broken down. This system enables the ground team to follow in real time the flight mission and to monitor thousands of crucial parameters. With a prototype such as Solar Impulse currently in an experimental phase, this system is an essential component without which, the mission was not possible. “Due to this inoperative piece of equipment produced specifically for this prototype, we were unfortunately unable to replace it and subsequently had to postpone this first attempt. “The entire team is of course intensively working to find a solution, however at this particular time we are unable to announce another date for the next trial.” Project leaders commented, with Chief Test Pilot Claude Nicollier reminding …
