Abstract:The purpose of this multi-year, multi-phase airplane cabin air quality research study was to: 1. Identify and measure levels of engine and auxiliary power unit bleed air contaminants 2. Identify sensor technologies to detect/provide warning(s) of bleed air contaminant events 3. Identify techniques to minimize airplane diversions from smoke, odor, fume events and 4. Assess potential health-related risks of human exposure (i.e., passengers and flight/cabin crew) to chemicals generated during contaminated air events. Phase 1 work assessed the current state of knowledge of engine bleed air/cabin air contamination events and evaluated the current state of sensor technologies that could be used to detect airplane engine bleed air/cabin air contaminants. Phase 2 work involved static aircraft engine stand tests and ground-based, on-aircraft tests. Phase 2tests assessed the capability of current, commercial off-the-shelf sensors to detect bleed air contaminants resulting from engine oil, hydraulic fluid, and deicing fluid, and included the collection and chemical analysis of engine bleed air contaminants resulting from engine oil, hydraulic fluid, and deicing fluid. Phase 3 work resulted in the toxicological review and interpretation of the chemical sample data to examine the potential health-related risks of human exposure to engine bleed air contaminants resulting from engine oil, hydraulic fluid, and deicing fluid.
The overall study produced multiple data sets and technical reports on sensor technology performance, chemical analyses of engine bleed air contaminants, and a toxicological assessment of the potential health effects of engine bleed air contaminants on passenger and flight/cabin crew.
