Inductive signal transmission system in an aircraft turbomachine

Abstract

Inductive transmission system for a signal in an aircraft turbomachine Transmission system (10) for a signal (S0) in an aircraft turbomachine, the system comprising a transmitting module (20) receiving the signal to be transmitted and comprising at least one magnetic field transmitter (22) fixed relative to a portion of the aircraft frame;and a receiving module (26) providing a transmitted signal (S1) and comprising at least one magnetic field sensor (28) rotatably fixed with a rotating drive element of the aircraft, wherein said at least one magnetic field emitter and said at least one magnetic field sensor are positioned so as to face each other in at least one determined angular position of the rotating drive element relative to the frame portion, and wherein, during rotation of the rotating drive element relative to the frame portion, the transmitting module is configured to emit, when the rotating drive element passes through said at least one determined angular position, a magnetic field value representative of at least one signal element to be transmitted.
