Abstract

Abstract: This paper uses SJTUICE (Shanghai Jiao Tong University Icing Simulation Code) method of prediction and develops method for the aerodynamic analysis on highlift configurations. After validating the supercooled large droplet (SLD), particle trajectory and icing prediction on multielement airfoils, this paper characterizes the SLD icing accretions and aerodynamic effects on highlift configurations and compares them with nonSLD conditions. The result indicates that the quantity of ice increases, and the upwind horn on the suctionside of the slat grows lager and extends downstream under SLD condition. It is remarkable to detect that the SLD condition induces the large increment of horn ice on leading edge of flap. The ice shape has a larger growth angle that is about to lead to the clogging of the gap. With the angle of attack ranging from 6° to 22°, the SLD condition has a larger degradation on the aerodynamic performance comparison with nonSLD condition. It leads to the decreasing of lift coefficient by 63.5% and causes stall to occur 8° earlier.

Key words: supercooled large droplet (SLD), highlift configurations, icing accretions, aerodynamic effect
