Abstract

A gas turbine engine is provided and includes a first fan blade (201₁) including a suction surface, a second fan blade (201₂) comprising a pressure surface (215) and neighboring the first fan blade (201₁) and a throat region (220) interposed between the suction surface (216) of the first fan blade (201₁) and the pressure surface (215) of the second fan blade. The throat region (220) includes a passage throat (221) located at a minimum distance between the pressure and suction surfaces. The first and second fan blades are configured such that a pre-compression region is defined in the throat region (220) ahead of the passage throat. Each of the first and second fan blades includes a mean camber line (MCL) defining a flattened suction surface.
