Title:
BLADE AND WIND TURBINE GENERATOR SET
Document Type and Number:
WIPO Patent Application WO/2024/000905
Kind Code:
A1
Abstract:
A blade (100) and a wind turbine generator set, the blade (100) being used in the wind turbine generator set, and the blade (100) comprising a blade body (1) and a vibration suppression component (2). The blade body (1) has an outer surface (11), and the vibration suppression component (2) is disposed on the outer surface (11). The vibration suppression component (2) extends along an axial direction (X) of the blade body (1), and the vibration suppression component (2) has an initial state (S0) and a contracted state (S1), the vibration suppression component (2) being able to switch between the initial state (S0) and the contracted state (S1). In the initial state (S0), the vibration suppression component (2) expands to a first volume and can disturb an airflow, so as to suppress vibration of the blade body (1) ;in the contracted state (S1), the vibration suppression component (2) can contract to a second volume, the first volume being greater than the second volume.
