Although the theme of AirVenture 2010 was "Salute to Veterans," the future of air travel was also brought to the fore – and that means electric airplanes. The focus on e-aviation culminated in the World Symposium of Electric Aircraft last Friday and among the many interesting designs discussed was Boeing's Subsonic Ultra Green Aircraft Research (SUGAR) Volt concept. Borne out of the same NASA research program that gave birth to MIT's D “double bubble” concept, the SUGAR Volt is a twin-engine aircraft design notable for its trussed, elongated wings and electric battery gas turbine hybrid propulsion system – a system designed to reduce fuel burn by more than 70 percent and total energy use by 55 percent. Could this be the future shape of commercial air transportation?
