Anti-torque device with rotor and stator rectifier careened, and phase modulation of the rotor blades, for helicopter.

摘要

P A stator (8) with fixed blades and aerodynamic profile (8) is mounted downstream of the rotor (7) with blades (10) in the transverse vein (6) passing through the hull (5) at the rear of the the helicopter. The blades (10) of the rotor (7) have an angular distribution about the axis of the rotor in irregular azimuthal modulation, such that any angle between any two blades (10) of the rotor (7) is different from any angle between two any blades (9) of the rectifier (8).
