摘要
提出一种基于负浮力设计思想的水下航行器,其原理是在运动时通过在固定机翼上产生的流体升力来平衡其负浮力。建立其空间六自由度动力学模型,并用龙格-库塔数值方法进行仿真求解和动力学行为分析。分析结果表明,与传统中性浮力自主水下航行器相比,负浮力水下航行器具有负载能力强、容积利用率高、升阻比大的优点。
An underwater vehicle designed based on negative buoyancy is proposed,which balances the negative buoyancy by the fluid lift generated on the fixed wing during motion.The spatial six-degree-of-freedom dynamic model is established,and Runge-Kutta numerical method is used to simulate and solve the dynamic behavior.In conclusion,compared with the traditional neutral buoyancy autonomous underwater vehicle,the negative underwater vehicle is of the advantages of high load capacity,high volume utilization and large lift-to-drag ratio.
