Cui Erjie, male, Han nationality, is a native of Jinan, Shangdong Province. His ancestral home is in Gaoyang, Hebei Province. He graduated from Beijing Aviation College in 1959.
Cui is a leading researcher in uplift aerocrafts using fluid control. He established, and developed, a new analytical method of aerodynamic flexibility of aircrafts with by creating a complicated-shaped aircraft. He also proposed the framework of "ground domino effect atmosphere-hydrodynamics" and explored the applied study of wind engineer and industrial aerodynamics. Cui created innovations in structural-resulted libration, aerodynamic flexibility of dissolute power, and physical fluid.
Cui is a member of the Chinese Academy of Sciences.
