摘　　要：以喷水推进型水下滑翔机为研究对象,对比理论计算、数值仿真和拖曳试验结果,验证数值仿真方法计算水动力的准确性.考虑水平翼对水下滑翔机滑翔效率和静稳特性的影响,通过设计正交仿真试验和利用惠克公式确定水平翼的参数配置.基于刚体六自由度动力学模型,建立喷水推进型水下滑翔机的动力学模型,对定常滑翔运动和水平面回转运动进行运动仿真.结果表明,滑翔运动时,随质心调节位移的增加,攻角减小、滑翔角和滑翔速度增大;水平面回转运动时,随舵角增大,回转半径和回转周期减小,并且航速越快,尾舵调节效果越好.研究结果对喷水推进型水下滑翔机的设计与应用具有指导意义.The theoretical calculation, numerical simulation and tank towing test results were compared to verify the accuracy of the numerical simulation method for calculating hydrodynamics of water-jet hybrid glider. Considering the influence of the wing on the gliding efficiency and static stability of the water-jet hybrid glider, the wing parameter configuration was determined by designing the orthogonal simulation test and the Whicker formula. The dynamic model of a water-jet hybrid glider was established based on a rigid body six degree of freedom dynamics model, and the motion simulation was performed for the steady gliding motion and the horizontal rotary motion. The results showed that with the increase of the displacement of the centroid adjustment block during the gliding motion, the attack angle decreased, and the gliding angle and the gliding velocity increased; the rotation radius and rotation period decreased with the increase of the rudder angle during the horizontal rotary motion, and the faster the velocity was, the better the rudder adjustment effect was. The results make reference to the design and application of water-jet hybrid glider.
