直升机-舰动态配合的舰面流场环境研究综述

研究了制约直升机-舰动态配合性能的首要原因——直升机的载舰在海上风场、舰面特殊结构、舰艇运动等因素作用下形成的非定常舰面紊流场。在总结早期直升机-舰动态配合试验研究特点的基础上,分析了舰面流场海上实测试验的方法及其发展;针对舰面流场模拟普遍采用的CFD技术,分析了舰面流场CFD仿真的发展过程及现状。评价了新型CFD方法——DES在处理大分离涡外流方面的优势,指出了DES在舰面流场仿真领域的光明前景。

Review on Shipboard Flow Study for Dynamic Interface of Helicopter and Ship

To study the main factor restraining the dynamic interface performance of helicopter and ship-an unsteady flow field formed on the helicopter carrier by sea breeze, special structure of the ship and ship movement. Based on the feature of dynamic interface test of helicopter and ship in early stage, the methods of shipboard flow measurement as well as its development were analyzed. As for the CFD technique-usually used in flow simulation, its development and status were discussed. The advantage of DES, a new method of CFD, in handling Large-separation external flow was introduced and its bright perspective in simulation of shipboard flow was pointed out.
