Fluid Dynamic Characteristics of an Underwater Towed Sound Generator.

摘要

An underwater towed sound generator, used in sonar research work, was found to be unstable when under tow. This document records wind tunnel tests carried out on a model of the towed vehicle. Investigations were concerned mainly with static stability characteristics and the effectiveness of various configurational changes in improving the stability of the vehicle. The reasons for the original instability are identified and proposals are presented for some minimal effort modifications to the vehicle to achieve satisfactory towed stability.
