Recently, the C919, China's first homegrown large jetliner, received its type certificate from the Civil Aviation Administration of China. The aircraft's water tank of the center of gravity adjustment system, piping and power system were all developed by He Junguo, a professor at the School of Civil Engineering of Guangzhou University, and his team over five years.

C919 has 158-168 seats and a range of 4,075-5,555 km. It will be put into commercial passenger operation in spring, and serve on its premium routes to Guangzhou, Shenzhen, Shanghai and other cities, according to China Eastern Airlines.
"It is a great honor for our team to participate in the development of C919's center of gravity adjustment system. " Professor He said proudly.
"Adjusting or maintaining the center of gravity of a plane in flight is the basis and premise of a series of work," He explained.
During the flight, the adjustment system can calculate the real-time weight and center of gravity of the plane according to ground weight, fuel consumption, and other conditions. It is also able to adjust the center of gravity by controlling the transfer of water weight in the front and rear cabins, which effectively guarantees the safety of flight tests.

At present, He Junguo and his team are carrying out research on two national fund projects and one major research and development plan of Guangdong Province. These projects help to promote the sludge digestion, the reduction and resource development of excess sludge in sewage plants.
He is also dedicated to advancing school-enterprise cooperation to improve drinking water quality in the Pearl River Drainage Basin.
