A rotor hub fairing system (36) for use in a counter-rotating, coaxial rotary wing aircraft is provided including an upper hub fairing (38) defined about an axis. A lower hub fairing (40) is similarly defined about the axis. An airfoil shaped shaft fairing (42) is disposed between the upper hub fairing (38) and the lower hub fairing (40). The airfoil shaped shaft fairing (42) has a thickness to chord (t/c) ratio in the range of about 20% and about 45%.
