典型舰艇空气尾流特性分析

Analysis of the Characteristics of Typical Ship’s Airwake

摘要:

舰艇空气尾流环境是影响舰载航空装备飞行安全的重要因素。借助CFD技术研究了舰艇空气尾流场内气流的运动规律、甲板上方涡流结构。应用激光片光显示系统对舰艇缩比模型的流态进行了风洞实验,并用流场实测数据对理论计算结果进行了校验。研究结果有助于指导舰艇外形优化设计和舰载航空装备的安全性分析。

Abstract:

The ship’s airwake environment has significant effect on the flight safety of shipboard aircrafts. Using CFD method, the aerodynamic natures of a missile destroyer’s airwake and fluids over the flight deck were investigated. Laser-sliced flow visualization system was employed to validate the vortex structure of the air fluid with a scaled ship model in the wind tunnel. The result obtained may help to optimizing ship design and safety analysis of shipboard aircrafts.
