| 摘 要： | 建立了在密度分层环境中热尾流特性的计算模型。通过试验测量得到了艇模热尾流轴线的浮升规律和热尾流横截面的温差分布规律、热尾流轴线处温差的衰减规律。利用模型试验结果，验证了本文提出的潜艇热尾流特性计算模型的有效性，同时利用该模型计算了实际核潜艇的热尾流特性，为红外探潜与热尾流制导技术的发展提供了依据。

| Abstract: | The calculation model of thermal wake characteristics of submarine in stratified flow is established in this paper. The lift law of the model wake axis, the distribution law of temperature difference at cross section of the the thermal wake and the attenuation law of temperature difference at the thermal wake axis are obtained from test. The validity of the calculation model is verified through the experimental results. The thermal wake characteristics of nuclear submarine is calculated based on the model so that scientific bases are provided for the infrared detection of nuclear submarine and the control and guidance of the torpedo. |
