Abstract
Airworthiness standards of China and America both give the maximum permissible concentrations of CO, CO 2 and O 3 in airliner cabin. The general specifications of aircraft engine (GJB241-87, GJB242-87) also have the maximum permissible concentrations of pollutants in the engine bleed air used for the air conditioning system. During airworthiness certification flight tests, the concentrations of these harmful pollutants in cabin are required to be tested and validated. According to these requirements, combined with active and passive control strategies, a new cabin air quality (CAQ) control system was presented based on nano-photocatalytic oxidation (NPCO) purification technique. A CAQ dynamic model was established and used to do simulation analysis of the CAQ control strategies. Results showed that the CAQ control system based on new NPCO device can well handle the CAQ problems in current airliner cabins, and the new CAQ control strategies may help to reduce the CAQ change amplitude, and to improve the CAQ as well.
