Analysis of the Designing Parameters of a Buoyancy Driven Underwater Vehicle

对浮力驱动水下航行器几组主要设计参数航行速度与航行角、净浮力的关系,航行器速度和航行器体积及压载系数的关系进行了研究。结果表明:浮力驱动式水下航行器的航行角在35.26°时,航行器速度最快;航行器的速度与净浮力的平方根成正比,净浮力越大速度越快;航行器的速度与压载系数的平方根成正比,压载系数越大速度越快,航行器速度与航行器的(VT)^(1/6)成正比。关键词:浮力驱动;水下航行器;净浮力;受力分析;

We analyze the relationship among the speed and the path angle,volume and ballast friction of a buoyancy driven underwater vehicle.The results show that （1） the buoyancy driven underwater vehicle is the fastest when the vehicle＇s path angle is near 35.26°; （2） the vehicle＇s speed is in direct proportion to the square root of net buoyancy,the bigger the net buoyancy,the faster the speed; （3） otherwise,its speed is in direct proportion to the square root of ballast friction,the greater the ballast friction,the faster the speed; （4） the vehicle＇s speed is in direct proportion to （VT）^（1/6）.
