Drone Propeller Analysis by Blade Element Momentum and Numerical Methodes for Autonmus Submarine Veichle

Nowdays, the use of Autonomous Submarines has increased for Various applications such as, Scientific, military and commercial research. In this paper, a drone type propeller for autonomous vehicle is examined from various aspects such as: performance, product material and hydroacoustics. Hydrodynamic and hydroacoustic results are validated. Numerical uncertainty was calculated and estimated. To select propeller, the coupling of Blade Element Momentum Theory (BEMT) method and Computational Fluid Dynamics (CFD) solver have been used. In the following, by the finite element method, several different materials for product the propeller with stress and minimum displacement of the blade tip constraint have been investigated. In order to examine the propeller from different aspects, a flowchart was proposed. The propellers were analyzed in terms of performance and strength and the displacement criterion for the blade tip was considered. In the last section, the hydroacostic results are validated and Sound pressure Level (SPL) is estimated and compared.
