Composite propellers are the potential alternative of conventional propellers because of their superior properties such as high specific stiffness and strength ratios. The industry is becoming aware of the advantages of composite propellers and an increasing trend towards it is noticed. Unfortunately, there is a lack of proper de-sign assessment tools for the certification of composite propellers. Therefore, it is essential to develop and validate the tools to evaluate the design of the composite propellers. This report is about the validation of a design assessment tool knownasComPropAppwhich is designed by Cooperative Research Ships (CRS) partners.ComPropAppis a specially designed tool for the FSI analysis of composite propellers by doing one-way coupling of BEM-FEM solvers. The boundary element method (BEM) solver gives it an edge over Reynolds Averaged Navier Stokes(RANS) solvers in terms of computation time and cost. Hence, it is suitable for the initial design stage. The validation of calculations is done by usingFebHeli; a propeller’s geometry which is used in the French Research Project. The project is divided into four steps. In the first step, a new blade scantling is defined, as FabHeli’s actual scantling can't be used for confidentiality reasons, and the propeller’s geometry is reconstructed based on the given input data and new scantling. In the second step, the FSI analyses are carried out by using the one-way and two-way coupling of RANS solver(Star-CCM+) and FEM solver (FEMAP) and Star-CCM+respectively. In the third step, the FSI analysis is carried out by usingComPropApp. Finally, the calculated values of stresses, displacement, and forces from both methods are compared.
