Aerodynamic characteristics and ducted shape design of ducted flying car propeller
摘要
Abstract
To design a ducted propeller that satisfies the requirement for high thrust efficiency during hover in a ducted flying car,a dedicated design methodology is proposed.Blade geometry is developed using blade element momentum theory in conjunction with ducted propeller vortex theory,and the resulting de-signs are refined through CFD-based corrections to meet target performance.Under hover conditions,the aerodynamic performance of the ducted propeller is evaluated and compared with that of an isolated propel-ler.The results indicate that,due to suppression of blade-tip vortices and the additional lift generated by the duct,total thrust is increased by 11.1%while power consumption is reduced by 10.5%relative to the isolated propeller.To further enhance hover performance,an innovative variable-duct propeller configura-tion is proposed,in which the flare expansion angle is dynamically adjusted to maximize inlet airflow dur-ing hover,yielding a 15.53%increase in total thrust.The study validates a high-accuracy design frame-work that integrates blade element momentum theory with CFD correction,providing theoretical and tech-nical support for efficient aerodynamic design of propulsion systems for flying vehicles.关键词
