Object and purpose of research. This paper studies non-conventional propulsors. The purpose is to apply numerical results yielded by Krylov State Research Centre studies on fundamental scientific matters in design of non-conventional propulsors. Materials and methods. The paper analyses the challenges in development of non-conventional propulsors (pod propulsion units (PPUs), CRPOD and RSN propulsors, rim drives, as well as waterjets of various types. It describes previous studies and mathematical models dedicated to fundamental matters of marine propulsion, as well as discusses how the concepts of applying this knowledge have been applied in design of new marine propulsors and what results have been obtained. Main results. This paper forms an integrated design approach to innovative propulsors of various types. For a number of propulsors, this paper discusses the concepts of their development based on numerical techniques, as well as demonstrates the efficiency of developed methods. Conclusion. Theoretical importance of this work is that it formulates unified approaches to development of non-conventional propulsor. This study demonstrates how Krylov State Research Centre uses the results of fundamental studies in practical design activities.
