METHODOLOGY OF PROPELLER STRENGTH CAlCULATIONS IN SETTLED AND EMERGING WORK CONDITIONS
Journal Title: Journal of Machine Construction and Maintenance - Year 2018, Vol 109, Issue 2
Abstract
In the paper, the methodology of propeller strength analyses is presented. Numerical calculations based on the finite element method were used during the analyses. Analyses methodology is based on solid state mechanics with loadings determined by fluid mechanics calculations. Several propulsion working conditions (including steady-state and transient fluid flow) were taken into account. In order to determine the optimal modelling method of the propeller, several different numerical models were compared, including a free model of the whole propeller and single blade with boundary conditions placed in the foot. The propeller optimisation was the main target of the analyses. After numerical calculations, the propeller mass saving (in comparison to classification societies’ empirical formulas) was achieved.
