Abstract (en)
A system (10) for detecting abnormal movement resulting from breakage of a shaft in a gas turbine engine. The system comprises a detection circuit including a frangible and brittle fuse portion (12) made from a conductive ceramic and a plunger (18) connected to or adjacent the frangible fuse portion, wherein the plunger may be displaced as a result of movement of the broken gas turbine shaft to break the frangible fuse portion (12) and thereby alter the detection circuit.
