A gear assembly (48) is coupled between the propulsor (42) and the spool (30) such that rotation of the turbine (46) drives the propulsor (42) at a different speed than the spool (30). The propulsor (42) includes a hub (76) and a row (72) of propulsor blades (74) that extends from the hub (76). The row (72) includes no more than 20 of the propulsor blades (74).",
