To study the main factor restraining the dynamic interface performance of helicopter and ship-an unsteady flow field formed on the helicopter carrier by sea breeze, special structure of the ship and ship movement. Based on the fea-ture of dynamic interface test of helicopter and ship in early stage, the methods of shipboard flow measurement as well as its development were analyzed. As for the CFD technique-usually used in flow simulation, its development and status were discussed. The advantage of DES, a new method of CFD, in handling Large-separation external flow was introduced and its bright perspective in simulation of shipboard flow was pointed out.
