Time Accurate CFD Analysis of Ship Air Wake with Coupled V-22 Flow

Abstract

The research objectives of this task are three-fold. The first objective is to predict the unsteady air wake over Navy class ships. A database of important air wake conditions is thus developed which can then be incorporated into a manned flight simulator. The improved simulation environment can then ultimately be used to train pilots and develop shipboard flight envelopes that would otherwise only be developed with expensive at-sea trials with real aircraft, crew and ships. The second objective is to determine the time-varying affect of the air wake generated by a ship on a hovering rotorcraft, in this case the V-22, and vice-versa. This analysis is used to analyze the causes of increased pilot workload at problem landings spots. The third objective is to provide an accurate and efficient design tool to aid in the development of improved air vehicle/ship interface designs for future Navy ships.
