Shipboard launching and reuse of a helicopter are always difficult tasks due to the airwake effects arisen from the interaction between helicopter and maritime structure. It is no doubt that the unsteady airwake would add complexity to the helicopter operating environments. Therefore, the flight control technique for helicopter would be more complicated than that of other Aerial Vehicle. In order to obtain the know-how regarding the safe-landing issue of helicopter, the airwake and ground effects between helicopter and maritime structure would be focused and studied through implements of numerical flow simulation. Since the dynamic flow pattern analysis by means of the field measurements and model-test experiments always cost much expenditure, the Sliding mesh technique involved in the CFD computation would be employed to predict the aerodynamic behavior of a helicopter. The numerical simulation could possibly provide a flexible way to investigate and reveal the flow physics involved in the safety design issue. Meanwhile, the valuable work done in this research could also supply sufficient aerodynamic characteristics of a helicopter to perform its safe taking off and landing mode.
