    摘要: A rotary blade (10,19) includes a fixed boundary layer control device (15,25,37) extending spanwise on a lower surface (14,23) adjacent the trailing edge (12,21) to improve the lift/thrust characteristics of the blade especially at positive incidence angles. It was discovered that expected detrimental effects at zero/negative incidence did not materialise and the reasons are identified. Such blades are particularly useful for helicopter sustaining and anti-torque rotors.
