Abstract
A method of producing an operational data for an aircraft turbine engine is provided that including: sensing an inlet airflow to an aircraft turbine engine for CMAS particulate matter, the sensing performed during one or more ground portions of a flight operational cycle of the turbine engine, the sensing producing sensor signals indicative of the presence or absence of the CMAS particulate matter; determining a presence or absence of an exposure by the turbine engine to a CMAS environment based on the sensor signals; and producing an operational data indicative of the presence or absence of said exposure by the turbine engine to said CMAS environment.

A method of producing cumulative operational data for an aircraft turbine engine, comprising:
- (a) sensing an inlet airflow to an aircraft turbine engine for calcium-magnesium-alumino-silicate (CMAS) particulate matter, the sensing performed during one or more ground portions of a flight operational cycle of the turbine engine, the sensing producing sensor signals indicative of the presence or absence of the CMAS particulate matter;
- (b) determining a presence or absence of an exposure by the turbine engine to a CMAS environment based on the sensor signals;
- and
- (c) repeating steps (a)-(b) over a predetermined amount of time and producing cumulative operational data indicative of the presence or absence of said exposure by the turbine engine to said CMAS environment over said predetermined amount of time.
A system for producing cumulative operational data for an aircraft turbine engine having an airflow inlet, comprising:
- an inlet debris monitoring system (IDMS) configured to sense an inlet air flow to the turbine engine for calcium-magnesium-alumino-silicate (CMAS) particulate matter, the IDMS configured to produce sensor signals indicative of the presence or absence of the CMAS particulate matter;
- a controller in communication with the IDMS and a non-transitory memory storing instructions, which instructions when executed cause the controller to:
- control the IDMS to sense the inlet air flow for CMAS particulate matter during one or more ground portions of a flight operational cycle of the turbine engine, and produce the sensor signals indicative of the presence or absence of the CMAS particulate matter;
- determine a presence or absence of an exposure by the turbine engine to a CMAS environment based on the sensor signals;
- and
- produce an operational data indicative of the presence or absence of said exposure by the turbine engine to said CMAS environment,
- wherein in the production of said operational data indicative of the presence or absence of said exposure to said CMAS environment, the instructions cause the controller to produce data relating to a cumulative exposure of the turbine engine to one or more CMAS environments.
