    Abstract: A rotor assembly for a gas turbine engine. The rotor assembly comprising: a rotor comprising a plurality of rotor blades, wherein the rotor is arranged to rotate about an axis of rotation; a sensor arranged to measure a rotational signal indicative of the rotational speed of the rotor at a measurement point on the rotor; and a processor in communication with the sensor. The processor is arranged to receive the rotational signal and derive a rotor impact signal based on an offset in the measured rotational speed of the rotor at the measurement point. The rotor has an axial length (L) parallel to the axis of rotation, and the sensing apparatus is arranged to measure the rotational speed of the rotor at a measurement point along the axial length of the rotor, the measurement point corresponding to a position at or near an antinode of a torsional oscillation of the rotor resulting from an impact event. A method of detecting an object impact event on a rotor of a rotor assembly of a gas turbine engine is also disclosed.
