Abstract
An apparatus includes first and second equipment health monitoring systems for a gas turbine engine. At least one parameter of the gas turbine engine to be monitored by the second equipment health monitoring system is different than a plurality of parameters to be monitored by the first equipment health monitoring system. The first equipment health monitoring system is electrically connected to a control system of the gas turbine engine while the second equipment health monitoring system is electrically isolated from the control system. As a result, the second equipment health monitoring system may be physically and electrically separate to other electronic systems of the apparatus.
Claims12
An apparatus comprising:
- a gas turbine engine including a control system configured to control operation of the gas turbine engine;
- a first equipment health monitoring system including a first processor, a first memory, and a first sensor array (i) positioned at various locations of the gas turbine engine to enable monitoring of a plurality of parameters of the gas turbine engine and (ii) being configured to generate first data for the plurality of parameters of the gas turbine engine, the processor being programmed to receive the first data generated by the first sensor array;
- a second equipment health monitoring system including a second processor, a second memory, and a second sensor array (i) positioned at one or more locations of the gas turbine engine to enable monitoring of one or more parameters of the gas turbine engine and (ii) configured to generate second data for the one or more parameters of the gas turbine engine, at least one of the one or more parameters to be monitored by the second equipment health monitoring system being different than the plurality of parameters to be monitored by the first equipment health monitoring system, wherein
- the first equipment health monitoring system is electrically connected to the control system of the gas turbine engine, and the second equipment health monitoring system is electrically isolated from the control system.
