Patent number: 11402304Abstract: An environmental sampling system includes a passage in an aircraft component and a removable collector disposed in the passage. The passage has an inlet at a first region and an outlet at a second region. When the aircraft component is in operation the first region is at a greater pressure than the second region such that air flows through the passage from the inlet to the outlet. The removable collector is configured to retain constituents from the air and to react with the media designed to mimic corrosion effects seen at higher temperatures on engine parts. The constituents can then be characterized and correlated to engine deterioration to predict maintenance activity.Type: GrantFiled: July 3, 2019Date of Patent: August 2, 2022Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Joel H. Wagner, Kevin W. Schlichting, Michael Joseph Murphy, Steven H. Zysman, Nigel David Sawyers-Abbott, Andrew A. Consiglio, Charles Waldo Haldeman, IV
