Abstract
Objective. The purpose of the analytical review is to identify promising areas of research to improve the efficiency of water propellers.
Method. The research provides an overview and analysis of modern propellers.
Result. The analysis of the design – layout and schematics solutions of propeller is carried out, methods of increasing the efficiency of propellers are revealed, the main directions of further research are formed. Prospects for the development of propellers are considered, structural and layout and circuit solutions are described that ensure an increase in the efficiency of the working process, which allows to form the main directions of further scientific research. Created promising circuit solutions are closely related to the use of modern numerical methods at all stages of design, new approaches to the creation of propellers will provide an increase in efficiency by 8-10%.
Conclusion. Increasing the efficiency of propellers, due to modeling workflows using numerical methods of hydrodynamics, and developing advanced schematics solutions, will not only increase the efficiency, but also improve the cavitation and acoustic characteristics of the propellers. The use of CFD calculations allows you to reduce the time, costs and volumes of product development work.
