Electric Propulsion
Boeing has created a team to study electric propulsion in future generation of subsonic commercial aircraft. SUGAR, which is an acronym for Subsonic Ultra Green Aircraft Research includes, BR&T, Boeing Commercial Airplanes, General Electric, and Georgia tech. There are five main concepts of the team is looking at. SUGAR Free and Refined SUGAR, are two concepts based on conventional aircraft similar like a 737. SUGAR High and SUGAR Volt, are both high span, strut-based wing concepts. The final concept is SUGAR Ray, which is a wing body hybrid. The SUGAR Volt concept has resulted in a drop in fuel burn greater than 70 percent and a reduction of total energy use by 55 percent. This reduction is the result of adding an electric battery gas turbine hybrid propulsion system.
