Rotor, aircraft, and method

摘要

The blade (20) has a root section (31) extending toward a free end section (41) of a root zone (30). A single convex zone (35) is transversely extended from a leading edge (23) toward a trailing edge (24). The convex zone comprises a pressure side (22'') and a suction side (21'') that are moved away from the root zone of a main rotation plane (P1) according to a direction (Z) parallel with a rotation axis (AXROT) of the blade and according to a direction opposite to a circulation direction of a fluid flowing through the blade to a maximum curve point (PCO) to the main rotation plane. An independent claim is also included for a method for reducing noise emitted by a rotor of an aircraft.
