Abstract
An assembly for a gas turbine engine according to an example of the present disclosure may include at least one rotatable airfoil, at least one vibration sensor operable to detect vibration of the at least one airfoil at one or more rotational frequencies, and a controller operatively coupled to the at least one vibration sensor. The controller may be operable to determine an accretion level associated with accretion of glass on the at least one airfoil in response to comparing vibration of the at least one airfoil at the one or more rotational frequencies to a vibratory pattern associated with accretion of glass. A method of operation is also disclosed.
