Behavior of passage shock waves in two-dimensional transonic symmetrical airfoil flows experimentally and a new determination model of the shock wave oscillation frequency is proposed. Shock wave position are measured by using two line scan cameras. Static pressures behind the shock wave are simultaneously measured by the high response static pressure probe. The result shows that phase delays of static pressure fluctuation are 45 degree at measurement points of X_b=1.4〜1.6.and fluctuation frequencies can be successfully estimated by the proposed determination model.
