海空两栖无人机是一种既能在天上飞,又能在水下航行的新型航空航海器,具有很高的研究与应用价值。设计了一种海空无人机的构型,为了研究该构型在飞行与潜水时的可行性,利用Fluent对海空无人机外部构型进行气动和水动特性计算分析。然后根据仿真与分析得到的气动系数与水动力系数得出,所设计的海空无人机外形布局分别符合飞行与水下航行要求,确定了外形布局的可行性,为进一步研究提供理论支持。

Amphibious air-sea UAV is an aviation and navigation device which can not only fly in the sky, but also navigate under water, and it has great research significance and application value. A structure of amphibious air-sea UAV was designed. The aerodynamic and hydrodynamics performances of UAV were analyzed with Fluent software to prove its feasibility. As results were analyzed, the calculated data could show the aerodynamic and hydrodynamic coefficient. As a result, the configuration of UAV could satisfy flying and diving quality with favorable aerodynamic and hydrodynamic performances, and it is confirmed that the UAV's shape structure is feasible and provides theoretical support for further research.
