TURBINE ENGINE ASSEMBLY FOR MEASURING THE VIBRATIONS TO WHICH A ROTATING BLADE IS SUBJECTED

摘要

The invention relates to a turbine engine assembly comprising a housing and a bladed wheel rotatable within the housing. The bladed wheel comprises at least one blade having a head opposite the housing. The assembly is characterized in that the head comprises a magnet and in that the housing comprises a first and second electrical conductor. Each electrical conductor is suitable for generating, across the terminals thereof, an electrical voltage that is induced by the magnet of the head opposite the housing and that represents vibrations to which the head of the blade is subjected when the bladed wheel is rotated. The first electrical conductor includes a first central portion extending around the rotational axis of the bladed wheel and comprising two mutually facing ends, and the second electrical conductor includes a second central portion passing through a space left by the first central portion between the two ends thereof.
