水陆两栖飞机船体水动力矩特性研究

船体水动力矩特性是水陆两栖飞机水动力性能的重要部分。为了研究某型飞机船体的水动力矩特性，开展了单船身模型水池力矩试验，详细研究了飞机纵倾角、断阶吃水及试验速度对船体水动力矩的影响，并对试验结果的可信度进行对比论证。结果表明该力矩试验得到的船体力矩特性数据具有较高的可信度，船体水动力矩随着断阶吃水和试验速度的增大而增大，而随着纵倾角则呈现先增大再减小的趋势。

The hydrodynamic moment performance study of a amphibian

the hydrodynamic moment performance is vital to amphibian, in order to study the hydrodynamic moment performance of a amphibian, a moment performance tank test is conducted, the test model is a single hull model, the influence of trim angle, sea gauge of step and test velocity on the hull moment performance is systematically analyzed, and the test reliability is also demonstrated. The results turn out to be that this kind moment performance model test measure is of high reliability, the hydrodynamic moment increases with sea gauge and test velocity, and increases firstly then decreases with trim angle.
