Simulation Research on Air Distribution Optimization of Civil Aircraft Cabin Ventilation System

The cabin ventilation system of civil aircraft is mainly composed of distribution ducting, which convey the mixed air from the mixing unit and the trim air to various areas of the cabin through the cabin distribution ducting to provide ventilation for the cabin. The design of the system directly affects the comfort of the passengers. This paper takes the cabin ventilation system of a civil aircraft as the research object, and investigates the air distribution of the left side of the rear cabin ventilation system. Flowmaster software is used to model the cabin ventilation system, and the air distribution of the cabin ventilation system is simulated, which meets the air distribution requirements of the cabin ventilation system, and provides a reference for the optimization design of the cabin ventilation system of civil aircraft.
