摘　　要：两栖飞行器是既能在地面上行驶又可以在空中飞行的一种新型飞行器。文章研究的涵道式飞行汽车是通过车身的主涵道螺旋桨产生升力,车尾的推进螺旋桨产生推力完成升降及前进。利用ANSYS-CFX对飞行汽车在空中飞行时的飞行姿态进行了仿真分析,得到飞行汽车的升力,翻滚力矩,俯仰力矩及偏航力矩等参数,并分析飞行汽车前飞状态的流场结构,根据数值结果对飞行汽车空中飞行姿态进行讨论。Amphibious aircraft is a new type of aircraft that can travel on the ground and fl y in the air.The culvert fl ying car studied in this paper generates the lift force through the main culvert propeller of the body,and the propelling propeller at the rear of the car generates the thrust to complete the lifting and advancing.ANSYS-CFX was used to simulate the fl ying attitude of the fl ying car in the air,and the parameters of the lifting force,rolling moment,pitching moment and yawing moment of the fl ying car were obtained.The fl ow fi eld structure of the fl ying car in the forward fl ying state was analyzed,and the fl ying attitude of the fl ying car was analyzed in detail according to the numerical results.
