Open publisher page 1 citations

Abstract

On the basis of the characteristics of Leishman-Beddoes(L-B) dynamic stall model, the method of parameters identification was put forward in order to expand the application range of L-B dynamic stall model and adapt to dynamic stall analysis of specific airfoil. The dynamic stall lift and drag were calculated with the parameters identified from the static stall lift and drag curves of SC-1095, the results agreed well with the experimental value.
