| 摘 要： | 参考水上飞机的横向稳性计算原理和海船稳性规范，建立了直升机的横向稳性计算方法，对漂浮姿态角、横向静稳性、横向动稳性、抗风浪等级等进行研究，并采用简单的方法进行燃油液面修正。完成了某型直升机漂浮特性试验，进行了横向稳性计算结果与试验结果的相关性分析。结果表明计算结果与试验结果的相关性很好。

| Abstract: | According to the theory of lateral stability computation and ship stability criterion, the paper established the method of lateral stability computation for helicopter. Flotation attitude angle, lateral static/dynamic stability, ＂wind and wave resistance level were studied, then simple method was adopted for oil surface correction. The test of lateral stability for helicopter has been accomplished, the correlation analysis was made between the lateral stability calculation results and the test data. The correlation was good. It meant that the method could be adopted for helicopter design. |
