Hex Turbofan Engine
Looking into the future of aviation for commercial aircrafts there are various viable options for engine and associated propulsion technologies. The team had to eliminate some of the possible solutions. Superconducting electric motors were alleviated considering weight factors and lack of technology readiness to fly long range commercial jets. Even prop-fans were eliminated considering its limitation on stalling speed of fan and higher noise levels. To avoid such problems we went ahead with an integrated Turbofan engine.
