| Popis: | Object and purpose of research. This work analyses stressed state of propeller with complex geometry depending on its operational conditions, including crash-stop scenario. Materials and methods. The study is based on laboratory and full-scale test data. Main results. It has been shown that blade strains of complex-geometry propellers under hydrodynamic loads must be sufficient to alter their hydrodynamic performance. It is pointed out that stresses in these propellers could be especially hazardous in terms of reliability in crash-stop conditions. Conclusion. This paper shows that low-speed propellers cannot be taken as design prototypes for high-speed propellers with complex geometry, otherwise there might be reliability implications. |
