SCREW FOR AIRCRAFT CAPABLE OF HOVERING, AND CORRESPONDING METHOD Russian patent published in 2020 - IPC B64C27/12 B64D15/12 B64C27/68 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to propeller designs. Screw (3, 4, 4', 4'') of aircraft (1) capable of hovering, comprises stator (10, 150), rotary element (11, 151), rotating around stator axis (10, 150), blade (13, 154), supporting element (36; 161), which supports magnetic field source (30) (B_S) and either is fixed, or is rotated at first speed (ω1) of rotation, and first electric circuit (32, 169), which can be rotated at second speed (ω2) of rotation. First electric circuit (32, 169) is electromagnetically connected to source (30, 163) so that electromotive force (emf_R) is induced by magnetic field in first electric circuit (32, 16). Screw (3, 4, 4', 4'') additionally comprises second electric circuit (65, 70, 90), which either is fixed, or is rotated at first speed (ω1) of rotation, and sensor (58), generating signal (V_c), connected to reverse electromotive force (bemf_C, bemf_S), induced in second electric circuit (65, 70, 90).

EFFECT: providing possibility of electric power supply of rotary components of bearing and tail rotors.
