摘要:

舰船在航行过程中会受到海洋大气环境的影响,导致在舰船艉部会产生舰艉流。在舰载机着舰的过程中,舰艉流的存在会对舰载机产生较大影响,导致舰载机着舰安全性和飞行品质的降低。文中研究了舰载机进舰过程中舰艉流的影响,结合美军标MILF8785C中关于舰艉流的相关说明,在Matlab环境中建立舰艉流模型并仿真舰艉流速度的空间分布,最终得到舰艉流在水平方向和垂直方向产生的总扰动速度。该仿真结果需要实测数据进一步确认。

Abstract:

Air wake will be generated behind the body of the ship which voyages in the sea under the influence of the oceanic atmospheric environment. The existence of the air wake will greatly affect the carrierbased aircraft, resulting in the decline of the safety and the flight quality of the aircraft in its approaching and landing. A ship air wake model is built to study the impacts on the carrierbased aircraft in its approaching and landing where the ship air wake exists, and the spatial distribution of the velocity of the air wake are simulated in Matlab on a PC with reference to the specifications of the MILF8785C standard. The total turbulence velocity of the air wake is finally obtained in horizontal and vertical directions. The conclusion from the simulation of the model needs to be further validated by more experimental data.

Key words: air wake, atmospheric disturbance, Dryden model
