一种直升机漂浮稳定性计算方法的研究

A Calculating Method of Helicopter Float Stability

参考水上飞机的横向稳定性计算原理和船舶稳定性原理,提出合理的假设,并以三维势流理论为依据,对液体粘性进行适当的简化处理,建立了直升机的漂浮稳定性计算方法,对漂浮姿态、横向稳定性、耐波性以及抗风浪等级进行评估。最终将计算结果和试验结果进行对比,结果表明所选择的方法可以用于工程预测。

Refer to lateral stability of the waterplane and ship, this work made logical assumptions, and proposed a helicopter float stability calculating method through some simplifications in the viscous liquid that based on three -dimensional potential -flow theory, then float attitude, lateral stability, sea keeping and sea wave resistant capability were computed. Finally, compared the test resuits to calculated results, it implied that the method this work used was applicable for predicting.
