This paper presents two simple implementations of blade element method used for propeller performance calculation-Blade Element Momentum Theory and Joukowsky method based on a simple vortex model. In principle, both methods require division of the blade of the propeller into finite number of sections (i.e. calculation points), over which a 2D flow is assumed. The focus of this paper is to investigate the dependency of the calculated solution on the number of sections and comparison of both methods. For this purpose, three propeller geometries were chosen and a simple method used for comparison was developed. The calculation was performed in LabVIEW interface implementing MATLAB code.
