SUGAR Volt

SUGAR Volt is the hybrid aircraft concept proposed by a team led by

's Research & Technology division. It is one of a series of concepts put forward in response to a request for proposals for future aircraft issued by

. It is proposed that SUGAR Volt would use two hybrid turbofans that burn conventional

jet fuel Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by Gas turbine, gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for ...

when taking off, then use electric motors to power the engines while flying. SUGAR stands for Subsonic Ultragreen Aircraft Research; "Volt" suggests that it would be at least partly powered by electricity. SUGAR Volt would have emissions about 70 percent lower than average airliners today. Noise pollution will also be lower than airliners today. This hybrid-electric approach however remains to be balanced against increased complexity, large electric engine and battery size and weight. Relying partly on electric power might reduce specific fuel consumption (SFC) compared to a standard turbine-only design (turbofan or lower-consumption turboprops). SUGAR Volt is designed with a long, braced, high aspect ratio wing that decreases

induced drag Lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, in aerodynamics, is an aerodynamic drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or ...

due to lift. The wings of SUGAR Volt would enable it to take off in a shorter distance and generate less noise. The outer wings of the SUGAR Volt should fold to save ground space, increasing weight.
