The results are presented of experimental investigation of the loss of the viscous droplet shape stability in the course of gravity sedimentation of droplet under conditions of blowing-over by an incoming stream at low Weber numbers (We < 7). A new scheme of a setup for studying the droplet deformation by aerodynamic forces is suggested, with the aid of which a qualitative picture of droplet deformation and an empirical dependence of the degree of deformation on the Weber number have been obtained in the range of Reynolds numbers Re = 490–2070.
