for Shipbord Flow Modeling

Dynamic combining of helicopter/ship is one of the most important phases to insure onboard helicopter flight safe-ty. On the basis of analysis on the factors involved in dynamic combining, a simplified plan was proposed to solve the cou-pling flow field under the rotor and above the shipboard. To take some ship-helicopter for instance, the key techniques inshipboard flow field simulation were described, including shipboard flow simulation with CFD, reconstruction of the flowfield for dynamic interface, and the typical trajectory of helicopter landing was described. Finally, conclusions were madeto find methods of shipboard flow field simulation for helicopter/ship dynamic combining, providing referance for relevant researchers.
