On March 7, 2017, Bell Helicopter presented a conceptual, futuristic looking aircraft. The mock-up presented is configured for eightpassengers, but will be capable of accommodating up to 12. On top of the aircraft are five "morphing" main rotor blades 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 reducenoise. The airframe is slightly bigger than that of a Bell 412.
