The results of a spatially and temporally resolved experimental study of the conical flame front kinematics of acoustically excited flames are presented. The basic assumptions which are widely used in theoretical flame kinematics considerations are verified experimentally. The propagation velocity and spatial evolution of the flame front disturbances are measured. Special attention is paid to the character of the flame end point motion. An elliptical path of the flame end point displacement is measured. The correspondence between the flame area and heat release rate oscillation is confirmed for a frequency range 10-300Hz. The effect of the flame curvature on the burning rate is examined and is found to be insignificant.
