  • Deliberately mistuned bladed wheel
    Patent number: 10844722
    Abstract: A bladed wheel of a turbomachine includes a disk extending around a longitudinal axis, in a median plane, and blades distributed regularly around the longitudinal axis and extending radially from the disk. The disk includes a web corrugated alternately upstream and downstream of the median plane, so as to introduce a deliberate detuning of the bladed wheel.

  • DELIBERATELY MISTUNED BLADED WHEEL
    Publication number: 20190330985
    Abstract: The invention relates to a bladed when (23) of a turbomachine (10), comprising a disk (25) that extends about a longitudinal axis (26) in a central plane (PM), and a plurality of blades (30) that are distributed at regular intervals about said longitudinal axis (26) and extend radially from the disk (25), the disk (25) being provided with a web (27) that is alternately cursed upwards and downwards relative to the central plane (PM) such that the bladed wheel (23) is deliberately mistuned.

  • Method for intentionally mistuning a turbine blade of a turbomachine
    Patent number: 10267155
    Abstract: The present invention relates to a method (100) for intentionally mistuning a turbine blade of a turbomachine (10), by providing raised portions (31) or slots (32), the position of which is calculated on the basis of a vibration analysis of the disk (steps a) to d)).
