Flow Characteristics and Parameter Influence of the Under-Expansion Jet on Circulation Control Airfoil by Meng He, Liu Zhang, Chang Li, Lei Zhao

“…The enhancement in the jet pressure ratio and jet velocity contributes to expanding the control efficiency and control boundary of circulation control airfoil under high subsonic incoming flow. However, because of an excessive jet pressure ratio, the jet separates prematurely on the Coanda surface, resulting in control failure. …”

Influence of geometric parameters of leading edge horn-ice on stall characteristics of airfoil by ZHAO Binbin, LI Xianping, LI Jie, ZHANG Heng

“…According to actual requirements of airworthiness certification of a large passenger aircraft, a family of horn-type ice shapes with different parameters are constructed based on typical supercritical airfoil and icing environment. By combining with wind tunnel test and numerical simulation methods, the parameter sensitivity of airfoil stall characteristics to the change of ice height and angle is systematically analyzed and the essential influence mechanism of the ice shape parameters leading to the change of separation bubble development under stall process is summarized, which provides a theoretical basis for ice airworthiness certification of large passenger aircraft.…”
