Prediction of Propeller Aerodynamic Performance based on Blade Element Theory
초록
영어
This study explores the application of Blade Element Theory (BET) to predict the aerodynamic performance of three-dimensional propellers, addressing the computational challenges associated with traditional methods like moving mesh and Multiple Reference Frame (MRF). By utilizing two-dimensional flow analysis to compute lift and drag coefficients, this approach enables rapid and efficient aerodynamic performance predictions with significant reductions in computational time. Comparative analysis with three-dimensional simulations reveals BET's accuracy, with thrust predictions showing slight overestimation at higher RPMs. Findings highlight BET's potential for preliminary propeller design, particularly for low-solidity, low-speed applications. This method provides an efficient alternative for optimizing propeller performance in electric vertical takeoff and landing (eVTOL) systems, pivotal for advancing Urban Air Mobility (UAM) solutions.
