Experimental investigation of water droplets deformation regularities during their motion in the air by the action of gravitational forces was executed. Characteristic sizes of droplets were varied in the range from 3 mm to 6 mm. Velocities of droplets movement attained to 5 m/s. The cross-correlation system of video registration was used. More than ten characteristic “strain cycles” of droplets during the 1 m distance motion by them thought the air were established. Characteristic of droplets forms, periods, dimensions and ranges were determined for all “strain cycles”. “Strain cycle” times dependences on velocity and sizes of droplets were established.
