12. A gas turbine engine assembly comprising:
-
a rotor bearing having a bearing lubricant flow; and
a telemetry module installed adjacent to the rotor bearing for detecting operational characteristics of the gas-turbine engine, the telemetry module having a telemetry coolant flow that is separate from the bearing lubricant flow. - View Dependent Claims (13, 14, 15)

16. A method of collecting engine data for a gas-turbine engine, the method comprising:
-
installing a telemetry module adjacent to a bearing of a production gas-turbine engine without disrupting a bearing lubricant flow to the bearing;
providing a telemetry coolant flow 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 (17, 18, 19, 20)
