摘要

针对机-舰动态配合问题,从甲板起降区流场特性和舰船流场对直升机起降操纵影响角度出发,研究了直升机复杂流场环境下起降特性。采用CFD仿真方法,分析了不同风向角下甲板区涡流场变化。考虑舰船流场对直升机气动环境扰动,基于Peters-He广义动力入流理论,建立了直升机舰面起降时飞行动力学模型,分析了甲板流场不同位置对直升机起降时操纵影响,为直升机安全起降提供有利参考依据。
        Aiming at the problem of helicopter/ship dynamic,helicopter take-off and landing characteristics is researched to study the ship deck airwake and helicopter operation.The airflow field above the deck is calculated by CFD method.In this paper,we focus on the deck airflow from different wind angles and vortex shedding.The flight dynamic model of ship/helicopter is established,based on gust penetration model of ship airflow Peters-He inflow model.We computed the helicopter take-off and landing characteristics on the deck different positions,which an important basis for ship helicopter safe operational limitation.
