Hydraulic Fluids and Jet Engine Oil: Pyrolysis and Aircraft Air Quality

摘要: Incidents of smoke in aircraft cabins often result from jet engine oil and/or hydraulic fluid that leaks into ventilation air, which can be subjected to temperatures exceed 500 °C. Exposed flight-crew members have reported symptoms, including dizziness, nausea, disorientation, blurred vision, and tingling the legs arms. In this study, authors investigated pyrolysis products one two fluids at 525 Engine was an important source carbon monoxide. Volatile agents organophosphate constituents were released all tested; however, neurotoxin trimethyl propane phosphate not found. The hypothesized localized condensation ducts, followed by mobilization when cabin heat demand high, accounted for mid-flight incidents. recommended monoxide data logged continuously capture levels during future
