摘要

摘要: 混合动力水下滑翔机是一种加装了鳍舵和螺旋桨推进系统的新型水下滑翔机。为了验证混合动力水下滑翔机的总体性能, 研究了其在海洋环境中不同工作状态下的操纵性。混合动力水下滑翔机除可进行无动力滑翔外, 为了提高运动性能, 提出了2种混合工作模式, 即有动力推进时结合重心调节与无动力滑翔时结合舵操作。根据动量和动量矩定理建立了水下滑翔机的空间运动数学模型和海流动力学模型, 对不同的工作状态进行了仿真。结果表明, 混合动力水下滑翔机的无动力滑翔与有动力推进的转换过程具有良好的操纵性和稳定性, 但在进行无动力滑翔时易受海流的影响发生偏移, 混合工作模式效果良好, 具有可行性。

Abstract: Hybrid power underwater glider is a new kind of underwater glider equipped with rudders and propeller system. To validate its performance, the maneuverability under different working conditions in the ocean environment was investigated. A mixed working mode was proposed for a hybrid power underwater glider to improve its navigation capability, i.e. adjusting the center of gravity when the glider is powered, and operating rudders when it is gliding without power. Spatial motion equations were established according to the momentum theorem and the moment of momentum theorem, and a mathematical model of ocean current was constructed. Then different working conditions were simulated numerically. The results show that satisfactory maneuverability and stability of the transition between unpowered gliding and powered propulsion are obtained, but deviation due to ocean current occurs during unpowered gliding period; and the proposed mixed working mode is feasible.
