Kostenko D. Influence of design data of lashing underwater systems on their operational characteristics

The dissertation is devoted to questions of perfecting the designing of lashing underwater systems having increased productivity. The ways of increasing the productivity are proved, the interrelation of productivity with the force and energy characteristics is shown. The phenomena connected with work of one-unit lashing underwater system were studied in detail. The technique of defining the design parameters of one-unit underwater system for a case of inspection of bottom surface from anchorage is developed. In the dissertation the combined lashing underwater system with the self-propelled underwater device, which has not been used and studied before, is described. Such system provides on 25...40 % higher productivity in comparison with one-unit. The technique of designing such system in stationary state and basic dynamic modes is developed. The description and results of the full-scale experiments confirming theoretically received conclusions are submitted.
