| 摘 要： | 舰船空气尾流场是直升机舰上起降时的主要环境条件,对直升机的操稳性能及飞行安全有很大的影响。通过某型舰模风洞试验的PIV结果,介绍了舰船空气尾流场特性,如:等速度场和截面流线图、舰船机库脱体涡等,分析了下冲气流、涡流区及开/关机库大门等对直升机着舰的影响,对保障直升机飞行安全有重要价值。

| Abstract: | The warship air-wake is a major environmental condition for the helicopter during take-off and landing from warship, which affects the helicopter's control and stability and flight safety. According to PIV results in a ship model's wind-tunnel test, the warship air-wake field characteristics are introduced such as velocity field and vorticity field, vortex shedding from ship hangar etc. and the effects of downwash and turbulent zone and opening/closing hangar door on helicopter's landing on shipboard are analyzed. It is valuable for helicopter's flight safety. |
