Experimental study of the motion of small-sized models through a two-phase medium

The paper presents the results of a study of the features of small-sized model motion through a two-phase medium (a thin stream of water in still air). The created ballistic setup is briefly described. Methodical experiments have been performed that have demonstrated the operability of the setup and the developed methods of synchronizing the model's flight through the measuring section and its photo and video recording. The first results concerning the features of the interaction of the model and the stream of water have been obtained. The main tasks of further research have been formulated.
