Design and aerodynamic characteristics research of ducted flying car
摘要
Abstract
To address the technical challenges associated with high-speed performance and extended endur-ance of flying cars,a hidden ducted aerodynamic design featuring a circular cavity is proposed.A parame-terized modeling approach was developed,taking into account the overall weight constraints of the flying car,as well as the specifications of the engine and annular cavity.Three-dimensional models of the outer surface,annular cavity,and twin tail fins were constructed to establish the aerodynamic configuration of the vehicle.To evaluate the influence of varying aerodynamic features,a comparative analysis between single tail and twin-boom configurations was performed through multiple simulation experiments using FLUENT software.An in-depth investigation of the aerodynamic characteristics of three configurations at angles of attack of 0°,3°,and 5° was conducted under both ground driving and flight conditions,with re-sulting cloud maps and aerodynamic characteristic curves obtained.The experimental results indicate that,under identical operating conditions,increasing the angle of attack leads to a rise in lift coefficient,drag co-efficient,and lift-to-drag ratio.Notably,the drag coefficient exhibited abrupt changes in the single tail and twin-boom configurations,whereas the double tail configuration demonstrated more stable aerodynamic be-havior,thereby better satisfying the safety and stability requirements of the flying car.关键词
