THE USE OF WIND TUNNELS FOR STUDIES ON UNDERWATER VEHICLES

Various hydrodynamic aspects of underwater vehicles, including drag, propulsion, stability and control, cavitation and noise are discussed in relation to vehicle design and operation. A design approach is outlined in which experimental measurements are used for dual objectives: to design an optimum underwater vehicle and to predict the performance of the full-scale vehicle at sea. It is explained how models are then created and full-scale tests undertaken in wind tunnels. Such tunnels are now considered an acceptable substitute for an underwater environment, and their use of wind tunnels for investigating particular hydrodynamic aspects is described in detail. Typical studies in the area of drag and propulsion, as well as that of stability and control, are discussed. The paper concludes with a summary of important existing applications of wind tunnels for design, testing and research associated with underwater vehicles, after which the prospects for the future use of wind tunnels for this type of work are considered.
