摘要： In a method, a first lubricant parameter is determined (204) during a first period of a gas turbine engine operating cycle. The first lubricant parameter is indicative of a first quantity of lubricant within a reservoir of the gas turbine engine. A second lubricant parameter is determined (210) during a second period of the engine operating cycle. The second lubricant parameter is indicative of a second quantity of the lubricant within the reservoir. The first lubricant parameter and the second lubricant parameter are compared (212) to determine a lubricant consumption parameter. The lubricant consumption parameter is indicative of a quantity of the lubricant consumed by the gas turbine engine during the engine operating cycle.

摘要： Described herein is a method of monitoring a condition of a component of a gas turbine engine, comprising: obtaining, with a non-contact monitoring sensor, monitoring data, wherein a portion of the monitoring data relates to the condition of the component of the gas turbine engine; obtaining, using a position sensor, positional data relating to the component's position; communicating the monitoring data and the positional data to a processing module, and analysing, using the processing module, the monitoring data and positional data to determine the portion of the monitoring data which relates to the component and determine a condition of the component. Also described herein is a system for monitoring and a gas turbine engine comprising the system.

摘要： A measurement system (52) for an aircraft gas turbine engine (10) includes an instrumentation hub (70) including at least one probe (54), and a shield hub (72) positioned axially adjacent the instrumentation hub (70). The instrumentation hub (70) is rotatable about a rotational axis (76). The shield hub (72) includes at least one shield (94) which is radially aligned with the at least one probe (54) of the instrumentation hub (70). The shield hub (72) is rotatable about the rotational axis (76) independent of the instrumentation hub (70).
