The mission of the human-powered submarine team is to design and build a high-speed controllable underwater vehicle. The team determined that the control system must meet the following criteria: create as little drag as possible, function efficiently, and have a quick response to the pilot's signals. Three different fin configurations are considered: a thrust vectoring system, a separate stability and control fin configuration, and fixed fins with movable trailing edge flaps. The three systems were simulated using a two-dimensional computer code, XFOIL. Results of turning moment and drag from each system are present, along with discussion. The fixed fins with control flaps are found to be the most efficient system, producing nearly /sup 1///sub 3/rd the drag of the other two systems for the same control moment. A detailed description of the final design is presented as it was developed for Phantom IV.
