测量有尾翼水下航行体横倾力矩的一种新方法

A Method for Measuring the Rolling Moment of Submerged Body with Tail Fins

象鱼雷、运载器等水下航行体决定其运动性能的安定面和操纵面，通常布置在尾部。就航行体的横倾运动来说，尾翼既可产生控制力矩和恢复力矩，也可产生于扰力矩。因此，试验测量尾翼引起的横倾力矩是很重要的。目前，模型试验采用的测量横倾力矩的方法精度较差，不尽人意。本文介绍一个新的试验方法。试验情况表明，数据基本合理、精度有了提高，是一个有开发前途的试验方法。

The motion perfortnances of submerged bodies,such as topedo,missile container and so on,depend on their stabilizing and controllable planes mounted on aft portion of the bodies. The resultant moment of tail fins,which could be the rolling moment,the restoring moment,or disturbing moment,as the case may be. As a consequence,it is most important to measure the rolling moment caused by stern planes.Up to-date the accuracy of expermental data on the rolling moment obtained by the existed methods are rather slower and unsatisfactry. A new testing method for improving accuracy is presented in the paper. The results of tests show that the test data are reasonable in the main and the accuracy has been improved,and it is an effective measured method.
