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.
