Tianjin University makes 'lung' for China’s C919

The Comac C919 is the largest commercial airliner designed and built in China since the defunct Shanghai Y-10. The comfort and environment of the cabin is an important part of the C919. Tianjin University has successfully finished the numerical simulation and optimal design of the air distribution system for the C919, making the air in the cabin 20 percent fresher than regular commercial airliners.
