Abstract:
For aircraft, propellers have higher efficiency than other forms of propulsion and demonstrate wide-range versatility. The close aerodynamic coupling between the propeller and aircraft fuselage necessitates a comprehensive design of propeller-driven aircraft for better performance. This paper first introduces the requirements of aircraft design for propellers, such as but not limited to their diameters, blade numbers, and airfoil configurations, accompanied by the multidisciplinary optimizing design methods for propellers. Then, it examines the ramifications of propeller layout on aircraft design, focusing on two novel propeller configurations: co-axial counter-rotating propellers and distributed propellers. Furthermore, the evolution of propeller design techniques is traced, and the application of Computational Fluid Dynamics (CFD) in computational aeroacoustics, three-dimensional shape optimization, evaluation of aerodynamic interference, and comprehensive aircraft design is summarized. This paper will serve as a valuable reference for designing and optimizing propeller-driven aircraft.
