摘要
采用数值计算的方法,研究了舰体周围的气流分布情况。给出了不同条件下气流分布的差异以及舰载机滑跃起飞过程对舰面气流分布的影响。计算结果表明,舰体周围的气流分布是相当复杂的,尤其在舰体不同位置会产生不同强度的漩涡。它对于舰载机滑跃起飞气动特性的影响是不可忽略的。侧向风会大大增加舰面气流的湍流程度。本文计算为进一步研究和改善舰面气流分布以提高舰载机滑跃过程的气动特性具有参考价值。
The distribution of airflow around the warship is studied with numerical simulation method in this paper. The difference of the airflow distribution in different conditions is obtained. The influence during the course of the aircraft ramp ski-jump take-off on the airflow distribution on the deck is also considered. A result in numerical simulation shows that the airflow distribution around the warship is considerably complicated ,especially different intensity eddies are generated in different displacements on the deck. Influence of the eddies on the air dynamic characteristics for the aircraft takeoff can＇t be neglected. The sideslip wind will greatly enhance the airflow＇s turbulent intensity on the deck. The numerical simulation in the paper plays an important part in further research and improving the airflow distribution on the deck to advance the air dynamic characteristics of aircraft during the ramp ski-jump take-off course.
