摘要：
A system and methods are provided for determining blade clearance for asymmetrical rotors. In one embodiment, a method includes detecting displacement data of a rotor blade coupled to a shaft, receiving tachometer data determined for rotation speed of the shaft, and resampling the displacement data of the rotor blade based on the tachometer data. Resampling may include sampling the displacement data at constant increments of shaft rotation. The method may also include determining blade clearance based on the resampled displacement data.
