Abstract: A method is provided of controlling a gas turbine having a shaft connecting a compressor to a turbine, as well as having a reheat system, and a gas turbine. The method includes the steps of: operating the engine using the reheat system to provide a mass flow rate of reheat fuel into a gas flow of the gas turbine engine downstream of an exit of the turbine; detecting a shaft break event in the shaft; and in response to this detection, maintaining the mass flow rate of the reheat fuel being provided into the gas flow downstream of the turbine exit, whereby the maintained mass flow rate of reheat fuel raises a back pressure downstream of the turbine and thereby reduces a rotational speed of the turbine.

Abstract: A conduit assembly for the communication of electricity, light or fluid, including at least one conduit, wherein the conduit assembly also includes a core member, the at least one conduit in contact with the core member and arranged in a convoluted path defined with respect to the shape of the core member, the at least one conduit thereby having a first direct length between its ends such that removal of at least a portion of the core member permits the at least one conduit to straighten in the region of the core member removal to increase its direct length to a second direct length, the second direct length being greater than the sum of the first direct length and the length removed from the core member.

Abstract: The present disclosure relates to a hydraulic fuse comprising: a fuse body defining a plenum, the plenum comprising: an inlet configured to couple to a first fluid location; and an outlet configured to couple to a second fluid location. The hydraulic fuse further comprises a first fuse element arranged to close the inlet, the first fuse element configured to open the inlet when a pressure differential between the first fluid location and the plenum reaches a first threshold; and a second fuse element arranged to close the outlet, the second fuse element configured to open the outlet when a pressure differential between the plenum and the second fluid location reaches a second threshold, wherein the first threshold is higher than the second threshold
