Part of ENFICA-FC (Environmentally Friendly Inter-City Aircraft – Fuel Cell) project at the University of Turin, and headed by Professor Ing. Gulio Romeo, the Skyspark project uses a Sicme Motori Valentino motor of 65 kW maximum output in a light wood airframe, the Pioneer 300. The goal is to set a speed record for electric aircraft, first with battery power, and second with fuel cells as the storage medium. The project has an aggressive schedule, with the first proposal in late 2005, and a complete airframe, motor, controller, batteries, fuel cells and hydrogen storage tanks being displayed in February y 2009. The plan is to stage g a flight g test in the late spring g or early y summer with batteries, establish a speed record (180 km/hr) and then, in the fall, attempt to achieve a speed record on fuel cells only. http://pdf.aiaa.org/preview/CDReadyMATIO07_1768/PV2007_7754.pdf San Carlos, April 24, 2009 http://www.enfica-fc.polito.it/en 38
“Sicme Motori, technological partner of SkySpark, is producing the Valentino engine, which will be propelling the aircraft. This prototype, which stems out of the cooperation with the Electrical Engineering Department of the Polytechnic of Torino, is very light and has a high performance: it only weights 25 kg and features a maximum power of 65 kW at a speed of only 2500 rpm. “Valentino is the crowning jewel of 45 years of industrial experience focused on research and innovation. “Sicme Motori is one of the first companies on the international scene to apply y Direct-Drive technology gy to electrical engines” g states Alberto Sola, Chairman of Sicme. “This has allowed us to do without the gearbox, guaranteeing a maximum energetic efficiency”. Gearless motors reduce maintenance needs enormously, have remarkable environmental advantages, guarantee outstanding performance and absence of noise, even at low power regimes. “Valentino is a Direct-Drive motor (synchronous, with permanent magnets) of a brushless kind. This means that, in contrast with a brush motor, it does not need electronic switches embedded on the main rotor in order to work. It uses particularly p y sophisticated p materials, , has an external rotor, and is cooled by liquid. “Always active in the field of innovation, Sicme Motori has been one of the first companies to invest in renewable energies. ‘We have been busy with wind power since 2002, well before it became a media hype’ says Alberto Sola, ‘and we are now working on a new generation of electrical engines that will find concrete applications in many important sectors, such as the automobile, to realize highly performing ecological engines’. “ San Carlos, April 24, 2009 From a SkySpark press release October 20, 2008 39
