Large airliner cabin air environment is an international hotspot issues, China's large aircraft project on safety, health,environmental studies demand urgent and comfortable cabin. In this study, the latest focus of the international aviation community and the development of a large airliner significant demand, focus on resolving two key scientific issues airliner cabin air environment control: (1)the cabin ambient air pollutant distribution and unsteady nonlinear transfer mechanism; (2)more than the physical characteristics of the cockpit environment coupled with the principle of multi-parameter target control. And around these key scientific issues, carried out the research six areas: (1)numerical simulation strategy for unsteady airflow in cabins; (2)the nonlinear emission and transport mechanism of pollutants in low pressure cabin; (3)cabin air quality and thermal comfort systems experimental evaluation criteria; (4)cabin environment design parameter system and compliance verification of airworthiness standard; (5)multifield coupling reverse cockpit environment design rationale; (6)the cabin environmental control systems dynamic adjustment mechanism of the whole flight status.
