A rotor or propeller with rotor blades (17a, 17b, 17c) and a passive pitch angle adjustment apparatus. The passive pitch angle adjustment apparatus includes levers (15a, 15b, 15c), rods (19a, 19b, 19c), and central rod (20). Levers (15a, 15b, 15c) are connected to rotor blades (17a, 17b, 17c) and rotate them around a respective pitch axis (13a, 13b, 13c). Rods (19a, 19b, 19c) are connected to levers (15a, 15b, 15c) and mechanically link levers (15a, 15b, 15c) with each other via central point (23) that is located outside rotor plane (1g). Central rod (20) connects central point (23) with base point (24) that is located in a longitudinal direction of rotor axis (1f). The passive pitch angle adjustment apparatus enables a cyclic pitch adjustment of the rotor blades and block a collective pitch adjustment of the rotor blades.
