AbstractA novel physics-based real-time computational method of representing the airwake of Navy ships to support rotorcraft shipboard landing simulation studies is proposed for research and development. In this method, the unsteady ship airwake is modeled usingvortex doublet elements shed from sharp edges of the ship superstructure, and the approaching rotorcraft is described by a panel-based fuselage model and freely distorting wake analysis. Use of fast panel methods and octree sorting structures may allowthis highly complex wake representation to be calculated in real-time, using networked computers in a parallel computation environment. The airwake model representation provides an appropriately detailed level of fidelity to capture handling qualitiesfeatures of importance to shipboard rotary-wing aircraft operations, while maintaining real-time computation throughput. This approach promises to revolutionize
