On March 7, 2017, Bell Helicopter presented a conceptual, futuristic looking aircraft. The mock-up presented is configured for eight passengers, but will be capable of accommodating up to 12. On top of the aircraft are five "morphing" main rotorblades which aim to allow the tip of each blade to move between different flight regimes. This feature is supposed to maximize efficiency and performance and reduce noise. The airframe is slightly bigger than that of a Bell 412.
