摘　　要：水下无控航行的研究是有控弹道设计的基础.为研究航行器从水下发射到出水前的弹道特征及影响因素,基于鱼雷航行力学导出了水下潜航的弹道方程,分析了舵面固定的水下无控航行器的作用力.弹道曲线的预测为航行器试验模型质心位置选取提供了依据,计算结果与试验符合良好.For submarine navigation the free motion is the basis of controllable ballistic curve design. To research determinants of underwater-vessel trajectory during the course from launch to undersurface, the ballistic equation governing the submarine navigation were educed based on the torpedo dynamics. Forces applied on the underwater vessel with a fixed control piston were analyzed. The ballistic curve prediction provides guidance for choosing centroid of test model, and the computational results coincide with tests very well.
