| 摘 要： | 舰载直升机是登陆舰实现"垂直登陆"的主要武器,研究舰面流场特性对直升机安全性能与操纵性都有重要意义。建立了某型登陆舰的三维模型,以风向角为30°,风速为15m/s的流场为例,通过数值仿真得到了飞行甲板上方的气流分布,经分析机库陡壁效应引起的下冲气流分量在机库后方形成了涡流区,在直升机的起降过程中应避免通过该涡流区,以保障直升机的安全起降、平稳飞行。

| Abstract: | Shipboard helicopter is an important vertical landing weapon for landing ship. Research on flight deck airflow is of great significance to the control and safety of the helicopter. With three-dimensional model of a certain landing ship established, the airflow distributions in flight deck were calculated by simulation in the condition of wind angle 30°and speed 15 m/s, the analysis of which showed that the downwash from han- gar steep face made the vortex area behind the hangar. The helicopter should avoid this area when taking off and landing for the safety and steady flight. |

| Keywords: | flight deck airflow landing ship take off and landing from warship numerical simulation |
