A method of detecting the angular positions of blades of a rotor wheel of a turbine engine, the turbine engine having at least two rotor wheels driven by a common shaft, the first and second wheels comprising respective first and second numbers of blades regularly distributed around their circumferences. The method comprises detecting (200) the passage of each blade of the first wheel past a first sensor, detecting (210) the passage of each blade of the second wheel past a second sensor, calculating the time intervals between the passage of a blade of the first wheel and the passages of each of the blades of the second wheel, and determining (230) the relative angular position of each blade of the first wheel relative to the angular positions of the blades of the second wheel, the first number and the second number being distinct and mutually prime.
A method of detecting the angular positions of blades of a rotor wheel of a turbine engine, the turbine engine having at least two rotor wheels each having a stream of air passing therethrough and being coupled together directly or indirectly, the first wheel having a first number of blades regularly distributed around its circumference and the second wheel having a second number of blades regularly distributed around its circumference,
A turbine engine comprising first and second rotor wheels, each passing a stream of air and coupled together directly or indirectly, the first wheel having a first number of blades and the second wheel having a second number of blades,
