Abstract
A gas turbine engine is provided with a braking device for stopping the compressor drive turbine if a common shaft interconnecting the turbine and compressor rotors breaks, the braking device including a conical ring carried by the turbine rotor at its downstream end and a structural member of a generally conical shape carried by the upstream end of the turbine exhaust casing such that the ring will frictionally interlock with the structural member if the shaft breaks.
