The aim of researches is determination of damageability lightweight buoyancy materials depending from exploitation conditions. Development of optimum compositions and structures on the basis mathematical damageability models. Planning of reinforcement charts the adaptive blade and the toroidal shells. Research methods and equipment - experimental and analytical methods, mathematical statistics. Equipment for the hydrostatical and mechanical tests. Theoretical and practical results, newness: The first offered to useing of Glass foam's as buoyancy material for submarine technique, adopted it's ability long time withstand hydrostatical pressure on depths to 2000 m under temperature to 250 - 300 С. The first shown, that damage Syntactic foam's during exploitation in arctic districts is related with phase transition "water to ice" in the pores of material and mathematical model of this process is developed. Possibility creation of screw-propeller with managed step without the use of mechanism of turn blade is proved. The adaptive blade which by action of hydrodynamic loading changes the corner of attack, that promotes efficiency coefficient of screw-propeller. The estimation of stability of geometrical form for the durable corps of submarine toroidal form under action of hydrostatical pressure is the first done. Efficiency of implementation. The results of research work are applied in industry of experimental adaptive blades of wind-powered generator on LTD "ESTA" Nikolaev. The sphere of the use is shipbuilding of surface and submarine tehnichnih facilities. Product Description popup.authors Вдовиченко Т.А. Гурская А.Л. Копыйка С.В. Кочанов В.Ю. Петрюк О.В. Попіней А.Л.
