![]() ![]() After an upgrade of the Sunseeker’s electronics in 2009, Raymond decided to develop a whole new aircraft, this time with two seats instead of one. Raymond, a protégé of solar flight legend Paul MacCready, took 21 flights and 121 hours in the air to make that historic crossing. Developed and flown by the talented Californian engineer Eric Raymond, the Sunseeker I crossed the United States in the summer of 1990. The Sunseeker family of solar gliders dates back almost 30 years. This albeit excellent piece of German engineering will set you back €205 000 (about US $260 000), onboard charger included. However, by using a better battery-charging process, its engineers managed to squeeze 500 extra meters of climb out of it, bringing the maximum altitude to 3500 meters on a single charge. It has the same 42-kW brushless motor and the same SAFT VL41M lithium-ion batteries used on most European satellites and the F35 Joint Strike Fighter. The aircraft’s motor and battery pack haven’t changed much from those of an earlier 18-meter-wingspan version. In fact, it’s the world first electric aircraft to receive certification by any aviation authority. The plane is an impressive machine, built with safety in mind: It’s one of the few production gliders equipped with a crash-proof cockpit, and the design and manufacturing process of each component has been thoroughly assessed by German aviation authorities. The new wing profiles, along with the newly optimized wing/fuselage interface, give the Antares 23E a glide ratio of 60-meaning that from a height of 1000 meters the Antares 23E can glide for 60 km. With its 23-meter wing-designed by the Dutch aerodynamics guru Loek Boermans and built by Germany’s Lange Aviation-the Antares 23E is the most advanced electric airplane money can buy. ![]() It will incorporate all the lessons learned over these past few years of intensive flight testing and publicity tours, in preparation for the real goal of Solar Impulse founders Bertrand Piccard and André Borschberg: a round-the-world flight in the spring of 2015. A new plane is being built in Switzerland-the HB-SIB. It’s not built to be practical, and it isn’t: It flies at an average speed of 70 kilometers per hour, and it fears rain and winds that any student pilot in almost any plane could handle without too much worry.ĭespite its pedigree, the fate of HB-SIA is sealed: The cross-U.S. That low weight and its sleek design mean it can get by on four 7.35-kilowatt motors. As a test bed for numerous more or less innovative technologies and construction techniques, the HB-SIA is a collection of impressive numbers: It has the wingspan of a major airliner (about 63 meters), but its honeycomb-shaped, carbon-fiber-reinforced structure keeps the weight down to that of a small car (1600 kilograms) a fourth of that weight comes from the batteries.
