为解决现有水下潜器系统组成复杂、丢失后难以搜寻等问题，借鉴扇翼飞行器理念，提出扇翼推进水下潜器的新概念，弥补现有水下潜器的不足。针对扇翼推进水下潜器的核心装置扇翼推进器的敞水性能问题，运用CFD方法对比分析了一定的来流速度下，扇翼推进器和可倾斜轴导管桨在定深直航工况下，产生同等负升力和推力条件下的敞水效率。结果表明应用在高升推比的水下潜器上时，扇翼推进器的敞水效率远高于可倾斜轴导管桨，一定程度上论证了扇翼推进水下潜器概念方案的可行性。
To solve the problem of the existing underwater submersible, for example, complex system composition and difficult to search after loss, drawing onthe concept of fanwing aircraft, a new concept of fanwing-propelling underwater submersible is proposed to make up for the deficiency of existing underwater submersible. Aiming at the open water performance problem of fanwing propeller which is the core device of fanwing-propelling underwater submersible, CFD method is used to compare and analyze the open water efficiency of the fanwing propeller and the tiltable duct propeller which produce the same negative lift and thrust under the condition of constant depth direct flights at a certain inflow velocity. The results show that the open water efficiency of the fanwing propeller is much higher than that of the tiltable duct propeller when it is applied to the underwater submersible with high lift-thrust ratio, which proves the feasibility of conceptual plan of the fanwing-propelling underwater submersible to a certain extent.
