Abstract: One of the design requirements of a heliostat is the ability to withstand storm wind loads in the stow position and operational wind loads in any position. To design a heliostat, therefore, one must be able to predict the wind loading on the heliostat for all elevation angles of the heliostat and all wind directions relative to the heliostat coordinate system. A companion paper has described a technique for using of Fourier analysis to fit a small number of correlations to a large experimental wind tunnel force and moment coefficient dataset for an isolated heliostat, and presented correlations for the lift and drag forces. In this paper correlations for the side forces and for moments about the three principal axes are presented, the behavior of the correlations is discussed and comparisons are made to recently published heliostat mean loading data.
