潜艇艉水平稳定翼加断板（Ｈ型艉布局）可以显著地提高其垂直面的运动稳定性和机动性，从而也可以缓解水平翼超宽问题，因而该布局在新型潜艇的设计中受到青睐。本文对Ｒｉｌｅｙ［１］机翼端板的系列试验和Ｄｅｍｐｓｅｙ［３］潜艇艉水平翼的系列试验的数据进行了重新分析，提出了稳定翼有效展弦比的概念．并基于此概念，提出了一套简洁完整的半经验计算方法，可用于潜艇Ｈ型艉布局的操纵性设计和预报。与实际艇型的模型试验结果的比较表明，该计算方法具有良好的精度和适用性。
The submarine 艉 horizontal stabilizer and plus plate (H-type 艉 layout) can significantly improve the stability and mobility of the vertical plane, which can also alleviate the problem of horizontal wing width, which layout in the design of new submarines favored . In this paper, we reanalyzed the series of Riley [1] wing end-plate tests and the series of Dempsey [3] submarine 艉 horizontal wings and put forward the concept of effective aspect ratio of the stabilizer. And based on this concept, a set of concise and complete semi-empirical calculation method is proposed, which can be used in the maneuver design and forecast of H-shaped submarine layout. The comparison with the model test results of the actual boat shows that the calculation method has good accuracy and applicability.
