Description du projet
Étude des effets de la qualité de l’air de cabine sur les passagers
L’apport d’air extérieur et les polluants présents dans les cabines d’avion affectent les passagers. L’amélioration de la qualité de l’air de cabine constitue donc un défi de taille pour l’industrie aéronautique. Le projet ComAir, financé par l’UE, étudiera la qualité de l’air et le confort des cabines, ainsi que le bien-être des passagers. Le projet passera en revue les études publiées afin d’identifier les polluants présents dans les avions et de reproduire les expositions à ces polluants à différentes densités d’occupation dans la cabine au moyen de simulations de vol dans le caisson basse pression d’une installation d’essais en vol. Le projet appliquera des profils réalistes de pression, de bruit et de vibrations, de température et d’humidité relative de cabine. En outre, ComAir contrôlera la qualité de l’air au moyen de capteurs bon marché avancés, qui permettront également d’observer les réactions physiologiques des passagers.
Objectif
The impact of reducing outdoor air intake in the total volume of air supplied to an aircraft on cabin air quality, comfort and well-being of passengers will be investigated. Pollutants that have been measured in aircrafts and are likely to produce negative effects on passengers will be identified by reviewing published studies. The exposures to these pollutants will be reproduced during simulated flights in the Flight Test Facility low pressure vessel which is the mock-up of the actual airplane cabin. Realistic profiles of cabin pressure, noise and vibrations, temperature and relative humidity will be applied. Roundabout 600 subjects will be recruited representing cross-section of flight passengers. Different outdoor air supply rates will be simulated at varied occupation density in the cabin, one that is currently applied (baseline) and others that are lower. At lower outdoor air supply rates more air will be recirculated. During each flight simulation concentrations of air pollutants will be monitored and passengers will evaluate their comfort and well-being. Air quality will additionally be assessed by an impartial sensory panel who will briefly enter the cabin. Besides these measurements that are requested by the call, the air quality in the cabin will be monitored with the advanced low-cost air quality sensors, while the passengers physiological reactions are monitored. The results obtained in the simulated flights will be used to examine whether per person outdoor air intake can be reduced from the baseline without any negative effects on passengers, and if so by how much. They will also be used to propose pollutants that could potentially be monitored in the aircraft cabin for the purpose of controlling cabin air quality. Recommendations for the future revisions of standards pertaining to ventilation in aircraft cabins will be the major delivery.
