Abstract
A sensor assembly for a gas turbine engine includes a telemetry module mounted at a rotor bearing compartment for sensing engine operational parameters and a cooling system for cooling the telemetry module separate from a rotor bearing lubricant flow.
Claims18
A sensor assembly for a gas turbine engine, the assembly comprising:
- a rotor bearing lubricant flow for providing lubricant to a bearing located in a rotor bearing compartment;
- a telemetry module mounted radially inward from a rotatable compressor assembly at the rotor bearing compartment for sensing engine operational parameters;
- and
- a cooling system which utilizes a gaseous nitrogen coolant for cooling the telemetry module separate from the rotor bearing lubricant flow.
1 more element
A gas turbine engine assembly comprising:
- a rotor bearing having a bearing lubricant flow;
- and
- a telemetry module installed adjacent to the rotor bearing and radially inward from a rotatable airfoil assembly for detecting operational characteristics of the gas-turbine engine, the telemetry module having a telemetry coolant flow which comprises a gaseous nitrogen coolant that is separate from the bearing lubricant flow.
A method of collecting engine data for a gas-turbine engine, the method comprising:
- modifying a bearing lubricant flow to a bearing of a production gas-turbine engine;
- installing a telemetry module radially inward from a rotatable compressor assembly and adjacent to the bearing for operation without disruption of the bearing lubricant flow to the bearing;
- providing a telemetry coolant flow which utilizes a gaseous nitrogen coolant to the telemetry module, wherein the telemetry coolant flow is separate from the bearing lubricant flow;
- and
- generating a signal based on engine data collected by the telemetry module during engine operation.
