圆碟形水下滑翔机外形设计研究

Research on Shape Design of Disk Type of Underwater Glider

圆碟形水下滑翔机是一种新型水下滑翔机,其外形明显不同于现有的传统水下滑翔机,目前尚未看到有关其外形设计的详细讨论。基于水动力分析技术和滑翔机的稳态运动方程,建立了圆碟形水下滑翔机的外形设计分析方法,进而实现了导流沿、机身高度对水动力和运动性能影响的分析。研究发现,导流沿结构会增加单位垂直高度对应的水平滑行距离,但也会降低水平方向的滑行速度;机身高度的降低会增大水平方向的滑行速度,但不影响单位垂直高度对应的水平滑行距离。

Disk type of underwater glider is significantly different from traditional ones.So far,shape design of this type of underwater glider has not been discussed in detail.Based on hydrodynamic analysis technology and the steady motion equations of the glider,shape design method of the disk type of underwater glider is established,and influence of diversion edge and gilder height on the hydrodynamic performance is analyzed.It is found that the horizontal gliding distance corresponding to the unit height is increased by the diversion edge,while the sliding speed in the horizontal direction is decreased.Decrease of the gilder height will result in the increase of the horizontal sliding speed,but has no influence on the horizontal gliding distance.
