The invention discloses a hover aircraft rotor (3) and a hover aircraft. The hover aircraft rotor (3) has a hub (5) which rotates about an axis (A) and has a number of blades (9); a drive shaft (6) connectable to a drive member of the aircraft (1) and connected functionally to the hub (5) to rotate the hub (5) about the axis (A); and damping means (15) for damping vibration transmitted to the shaft (6), and which include a mass (17) designed to oscillate, in use, to oppose transmission to the shaft (6) of vibration generated by rotation of the blades (9); the mass (17) being free to slide parallel to the axis (A), to oppose transmission to the shaft (6) of vibration having main components along the axis (A).
