| 摘 要： | 应用粒子图像测速技术(PIV)获得了舰船空气尾流场特性,介绍了试验模型及PIV设备的安装方法和试验方案.试验表明:舰船机库及上层建筑物对飞行甲板上方区域的流场影响较大,使尾流场形成了死水区、U形脱体涡及下冲气流等,对直升机舰上起降以及临近舰船作业时的操稳性能有很大影响.根据试验结果,合理选择直升机的进场方向及舰船航向或打开机库大门有利于直升机舰上起降安全.

| Abstract: | The characteristics of warship air-wake can be obtained by means of particle image velocimetry(PIV).This paper presents the installation of test model and PIV set up,and the test scheme.Test results show that the hangar and superstructures affected largely flowfield over flight deck,and brought about the "dead water regions" and U-shaped vortex and downwash,thus greatly influencing the helicopter's control and stability when take-off/landing from warship and closing to the warship.According to the test results,it's conducive to the safety of helicopter's take-off and landing to properly choose the approach course of the helicopter and course heading of the warship or to open hangar door. |
