A system and method for determining leakage in a fluid supply line assembly are provided. The system includes a source of pressurized fluid, a pressurized fluid load, and a fluid supply line coupled to the source and the load. The leak detection system also includes a source isolation valve configured to control a flow of fluid into the fluid supply line from the source, a load isolation valve configured to control a flow of fluid from the fluid supply line to the pressurized fluid load, and a processor communicatively coupled to a memory device. The memory device includes instructions that when executed by the processor, cause the processor to close the load isolation valve and open the source isolation valve to supply pressurized fluid to the fluid supply line, and after a predetermined interval, determine a leakage of pressurized fluid from the fluid supply line.

Fluid supply line leakage detection system and method

Systems and methods for shutting down a gas turbine engine in response to a severe mechanical failure include determining a rate of change of one or more process conditions. If the rate of change of the one or more process conditions exceeds a respective predetermined failure threshold, a potential severe mechanical failure of the gas turbine engine may be determined. Steps may be taken to confirm the potential severe mechanical failure of the gas turbine engine. In response, an engine restart is prevented.
