Abstract
A system for monitoring the displacement of turbine blades that includes a turbine blade with a cutting tooth and one or more sensor wires, each sensor wire including a severable portion, that become severed by the cutting tooth as turbine blade displacement occurs. The sensor wires may be embedded in a honeycomb, which may be an area of abradable material attached to turbine shrouds. The sensor wires may include a plurality of radial sensor wires embedded in the honeycomb at varying predetermined radial distances from a turbine rotor. The sensor wires also may include a plurality of axial sensor wires embedded in the honeycomb at varying predetermined axial locations along the length of the honeycomb.
