本文研究了使用经验方法来估算流线型水下航行器的水动力导数。这些是出现在控制飞行器运动的微分方程中的系数。美国空军的Datcom-一种用于确定飞机的类似气动稳定性导数的方法-被用来执行不可压缩介质中的无量纲导数的估计。然后使用水的性质将衍生物量纲化。由于压缩性效应在Datcom中占很大一部分，并且在本申请中被忽略，因此该技术的使用相对简单。这里列出了Datcom获得的结果，并与其他来源的测试结果进行了比较。>
This paper investigates the use of an empirical method to estimate the hydrodynamic derivatives of streamlined undersea vehicles. These are coefficients which appear in the differential equations governing the vehicle's motion. The USAF Datcom-a method developed to determine the analogous aerodynamic stability derivatives of aircraft-is used to perform the estimation of the non-dimensional derivatives in an incompressible medium. The derivatives are then dimensionalized using the properties of water. Because compressibility effects make up a large part of the effort in the Datcom, and are neglected in the present application, the use of this technique is relatively straightforward. Results obtained with the Datcom are presented here and compared to test results from other sources.>
