针对现阶段水下滑翔机水下航速慢，以岸基或船基部署时转场至预定作业区耗时过长的问题，本文在其原有机翼基础上设计一种使用亚音速对称翼型的矩形可断机翼。通过断翼的方式，使水下滑翔机兼容水下滑翔与空中滑翔功能，具备了跨介质滑翔的基础；采用计算流体力学方法，构建一种采用该机翼的跨介质滑翔器数值计算模型，开展滑翔器在该机翼影响下的空中气动特性数值模拟试验。试验结果表明，在本文研究的范围内，使用该亚音速对称翼型、可断机翼的跨介质滑翔器在空中滑翔时平飞失速速度不低于90.5 m/s，同时具有较好的升阻比特性、俯仰特性，在主要工况下也具备较好的静稳定度，能够以0.8 Ma初速开始空中滑翔，可有效减少滑翔器向预定作业区转场所耗费的时间。
In response to the current problem of slow underwater speed and long transition time to the predetermined operation area when deploying on shore or ship, this paper designs a rectangular breakable wing using subsonic symmetric airfoil based on its original wing. By breaking the wings, the underwater glider is compatible with both underwater and aerial gliding functions, providing the foundation for trans-media gliding; A numerical calculation model for a trans-media glider using the wing was constructed using computational fluid dynamics methods, and numerical simulation experiments were conducted on the aerodynamic characteristics of the glider under the influence of the wing. The experimental results indicate that. Within the scope of this study, a trans-media glider with a subsonic symmetric airfoil and a breakable wing is used for horizontal flight with a stall speed of no less than 90.5 m/s during aerial gliding. It also has good lift drag ratio and pitch characteristics, and good static stability under main operating conditions. It can start aerial gliding at an initial speed of 0.8 Ma, effectively reducing the time required for the glider to transition to the predetermined operating area.
