Abstract:The purpose of this project was to provide a data-driven process to identify sensing technology with good potential for detecting bleed air contamination from engine oil, hydraulic fluid, or deicing fluid. An on-wing test was conducted in February 2022. A test on an engine test bed was conducted in May 2022. Sensors and instruments were identified, and a test plan was developed. Testing was conducted over a period of approximately one week. Results from this test with respect to sensor ability to detect bleed air contaminants was used on-wing tests performed in 2023. Data analysis for the testing in 2023 is ongoing and will appear in a separate report. Key objectives of the project are to identify sensors and sensor technology with the potential to detect one or more of the three aforementioned bleed air contaminants.
