The deformation of water, kerosene, and ethyl alcohol drops traveling a distance of up to 1 m in air with different velocities (1–5 m/s) is recorded by high-speed photography (the frame of the cross-correlation camera is less than 1 µs). It is shown that the shape of the drops varies cyclically. Several tens of “deformation cycles” are found, which have characteristic times, drop size variation amplitudes, and number of shapes. It is found that the velocity and size of the drops influence the parameters of their deformation cycles. Experiments with the drops are conducted in air at moderate Weber numbers (We < 10).
