| 摘 要： | 舰船上层建筑是诱发舰船舰面空气湍流的主要因素,对于具有全通飞行甲板的舰船,其岛式上层建筑的外形及布置则出现了多样化的趋势,对迎风方向后方的气流场形态势必会产生影响.为了解上层建筑外形及布局形式的变化对舰船空气流场,尤其是对舰载机起降影响的初步规律,通过定常同等试验工况条件下,建立多种形式的上层建筑以及变化研究模型上层建筑纵向的布置位置的数值三维模型,对5种模型分别进行数值模拟计算,分析和观察由此产生的气流场变化,对计算结果进行取值分析.通过各模型及原型舰模型间气流场特性的对比,所得出的有关结论与目前实际的舰船产品所采用的布置形式决策是一致的.

| Abstract: | The ship's superstructure is a primary factor that would causes turbulence in the air, and it is sure to change the ship's air-wake when the layout of these structures has been changed. This paper has simulated five different layout arrangements for a number of conditions, attempted to identify the influ- ences to the ship's air-wake, especially to the taking-off / landing for the ship-based aircrafts. The eval- uation was made based on the simulation results. Those analyses verified the real layout decisio... |
