ESDU 82031 provides force and moment coefficients for use
primarily in estimating mean wind loading on stationary or slow
moving paraboloidal reflectors such as are used for microwave
communications antennas, radio telescopes and solar energy
concentrators. The data may also be used to estimate the mean
loading induced by other gas or liquid flows over paraboloidal
shapes. The data apply for solid or perforated-surfaced
paraboloidal antennas with focal length/diameter ratios between
0.15 and 0.5 and with minimal backup and support structures. The
effects of backup and support structures and of other nearby
antennas are discussed briefly. Also discussed are the effects of
turbulence, shear flow and hysteresis of the flow. A Calculation
Sheet provides a step-by-step procedure for calculating the basic
forces and moments in a body-axis system and a method and equations
for conversion to other axis systems are also provided.
