PURPOSE: A helicopter anti-torque tail rotor blade is provided to improve design of a free end of the blade and reduce acoustic emission of an anti-torque tail rotor. CONSTITUTION: A helicopter anti-torque tail rotor blade includes a leading edge(8), a trailing edge(9), and an end(14c). The trailing edge interacts with an air current of a rear part of the leading edge. The end is extended between a reference section(51) and a section(11) outside a radius direction for a rotation axis of the blade. Length of a cord at the end decreases as it goes from the reference section to the end. In the end, the leading edge and the trailing edge are combined.

A proprotor blade (27a, 27b, 127a, 127b) having a fixed, spanwise, leading edge slot (215) located in at least the inboard portion of the proprotor is disclosed. The slot (215) is formed by a selectively shaped slat (217) disposed in a selectively shaped recessed area (219) located at the leading edge (202) of the main portion of the proprotor blade. The slot (215) is selectively shaped so that a portion of the airflow over the lower airfoil surface of the proprotor blade is diverted between the main portion of the proprotor blade and the slat (217) and exits at the upper airfoil surface of the proprotor blade. The present invention may be used on both military-type tiltrotor aircraft (11) and civilian-type tiltrotor aircraft (111) with only minor variations to accommodate the different shapes of the proprotor blades.

The invention relates to a rotor (1) through which a fluid flows in a main direction of flow (H) and which is provided with at least one rotor blade (4), said rotor blade being arranged in such a way that it can rotate about a rotor axis. The rotor blade (4) extends away from the axis of rotation (2), into the fluid, at least in sections. The rotation (D) of the rotor blade (4) about the axis of rotation (2) in a predetermined direction of rotation produces a propulsive thrust in the opposite direction to the main direction of flow, or a torque is produced about the axis of rotation as a result of the flow. The aim of the invention is to reduce the trailed tip vortex at the end of the rotor blades of rotors of this type and therefore to reduce the fluidic losses and flow noise. To this end, the rotor blade (4) extends in at least two partial blades (5, 6) at a set distance from the axis of rotation and forms a loop. One partial blade (5) extends in the direction of rotation (D) in relation to the rotor blade, at least in one area close to the rotor blade. The other partial blade extends in the opposite direction to the direction of rotation (D) in relation to the rotor blade (4), at least in one area close to the rotor blade (4). The two partial blades (5, 6) are interconnected in one piece at their ends so that they encompass a loop surface (12) through which the fluid flows, said loop surface extending essentially crosswise to the main direction of flow.
