The vibratory motions are primarily excited by the power plant. At operational (design) speeds, panels vibrate in their fundamental modes and those associated with their higher harmonic frequencies. The panel motions have rather well-defined energy spectra, which depend on both the structural design, position of the panel and the rotational speed of the single or multiple power plants. The panel motions will interact with the vortices in the adjacent turbulent boundary layer. The interaction can result in either an increase in the frictional drag or a decrease. Because of this, the argument is made that the designs of the panels and their support systems should include considerations of this hydroelastic effect.

The system is sized to provide 125-kW/sub e/ power output when experiencing 3-m waves. A novel design of a pneumatic turbine has been constructed and is awaiting the commencement of a steady-state test program. Modeling

Results of the analysis are then compared with experimental data in a study of the relative air ...
