First Claim
Patent Images
1. 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.

11. 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. - View Dependent Claims (12, 13)

14. 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. - View Dependent Claims (15, 16, 17, 18)
