Investigation of Trimaran helideck wake field based on superstructure optimized curvature

Helideck design is one of the main objects in the naval vessel design process. Despite structural constraints that affect the flight deck of the helicopter takeoff and landing performance is on board these vessels. There's hanger or any other structure in front of the flight deck will cause turbulent flow through to flight deck then the floating topside ship design should be designed that at least there is turbulence on the flight deck. Today, Trimaran for use in military industry with unusual attention Pavements have been. The most complex matters, which is angled topside addition to complying with the requirements of stealth, must create the best one on the flight deck. First, to select the correct flow forecasting model in turbulent flow, flow modeling was evaluated on a staircase. Six basic geometry was changed in the geometry in order to reduce the separation zone and helicopter landing zone were analyzed together finally, the best geometry on the deck of one flow-based product.
