Purpose. The study involves: 1) formation of 3D propeller models under study; 2) studying of the effect of profiling the blade of the propeller on its hydrodynamic characteristics; 3) development of a methodology for specifying optimal project parameters for modeling the operation of a propeller in free water. which in the future could be recommended when simulating similar tasks in t... https://parisnaturalfoodes.shop/product-category/vitamin-d-3-1000iu/
