Object and purpose of research. This paper discusses possible applications of multi-mode adaptive-pitch propeller in coaxial contra-rotating propeller systems. The study compares efficiency calculation results for these propellers and their conventional FPP counterparts. The authors also give a design calculation layout for coaxial propellers as per hydrodynamic test diagrams for solitary FPPs, as well as demonstrate their hydrodynamic calculation. Calculation results confirm that multimode adaptive-pitch propellers may considerably increase the efficiency of a coaxial propeller system in high-load conditions. The study also demonstrates that coaxial propeller systems have greater efficiency also when they are made up by solitary FPPs. These results might be useful in practical design of various ships. Subject matter and methods. The study relies on hydrodynamic test data for solitary FPPs and gives layouts for design and verification calculations of coaxial propeller systems. Main results. These data could be used to estimate the efficiency of coaxial propulsion for given ship design. Conclusion. The study shows that multi-mode adaptive pitch propeller tend to increase overall efficiency of coaxial propeller systems in high-load conditions as compared to FPPs.

Object and purpose of research. This paper is an integrated study of extruded polystyrene foam (XPS) practicability for three-layered composite hull structures of small craft. Subject matter and methods. Mechanical properties of composite materials and their components are determined experimentally (three-point bending, longitudinal tension/compression). Elastic properties and limit-state characteristics are obtained from beam theory, mixed model of composite beam, finite-element method, as well as solution of geometrically non-linear contact problems as per Newton-Raphson iterative technique. Main results. The study illustrates final diagrams for structural responses of investigated composite beam, filler and binder as functions of pre-defined displacement of test rigging. It also gives the estimates for equivalent Young’s moduli, as well as preliminary positive opinion about the practicability of XPS as a substitute for the conventional wood veneer in composite structures of small ships. The paper also presents a structurally similar FE model suitable for prediction calculations of large complex structures that can be tested only when the whole full-scale hull is available. Conclusion. This study formulates and solves the elastic problem for the investigated XPS-based sandwich panels. The results give an idea about the practicability of this material for shipbuilding applications.

Object and purpose of research. The object of research is a polymer composite material of syntactic type, which is a heterogeneous medium consisting of a polymer matrix filled with spherical inclusions – micro spheres. The purpose of work is to increase the strength/weight ratio of syntactic under hydrostatic pressure based on the analysis of processes at the material micro structure level, which let us identify the influence of initial components (micro spheres) and polymer matrix on the material density and ultimate state. Subject matter and methods. The Initial data are syntactic composition and structure as well as characteristics of its components. Numerical studies were performed using the earlier developed structural model of syntactic deformation and failure implemented into С++ software. Main results. The elastic and strength characteristics of the matrix and mico sphere glass are shown to have influence on the syntactic density and strength. Based on the size distribution of micro spheres and its influence on these characteristics, recommendations are formulated regarding development of the bi-dispersed mixture of MS-BP micro spheres. Application of such mixture made it possible to develop a new syntactic foam with required density and strength characteristics. Conclusion. The newly developed numerical method for prediction of syntactic characteristics takes into consideration the size distribution in micro sphere structures and allows optimized development of novel materials. The characteristics of new material obtained on the basis of developed guidelines have been verified by experiments.

Object and purpose of research. This paper discusses the effect of man-made underwater noise upon marine ecosystems. The purpose was to investigate the international practice of applying the risk-oriented approach to determination of environmental impact for man-made underwater noise in terms of marine ecosystems, as well as to discuss the introduction of risk management tools and conceptual models of ecosystem-based management of man-made underwater noise, including the Arctic areas. Subject matter and methods. This paper is based upon the methodical materials developed by KSRC, international risk management standards, as well as Russian and foreign publications in this field. The study relies on system analysis methods. Main results. The study analysed the results of international investigations regarding the assessment of man-made underwater noise effect upon marine ecosystems using the methodology of environmental risk management. It also discussed conceptual approaches to the assessment of marine noise pollution. As a case study, this paper discussed a regional environmental risk assessment in terms of shipping noise effect upon whales. The study concludes that risk-based and ecosystem-oriented approaches are possible and practicable to apply in man-made underwater noise management so as to preserve biodiversity and environmental status of Russian seas. Conclusion. International projects and programs rely on risk-based assessments in their approaches to the investigation of man-made underwater noise effect upon marine ecosystems. Russia needs its own scientific basis for man-made underwater noise management based on the methodology and practice of risk-oriented approach.
