ESDU 83020 provides pressure distribution data for both surfaces
of simple, isolated, paraboloidal antennas in uniform flow. For
incidences of 0 and 180 degrees the data are presented as radial
pressure distributions for focal length/diameter (f/d) ratios from
0.2 to infinity (a flat disc). For incidences of 60, 90 and 120
degrees, plots of constant pressure contours are provided for f/d
ratios of 0.33 and 0.4. A suitable approach is suggested for
interpolation for other incidences and limited interpolation or
extrapolation for other f/d ratios, and a blank grid is included on
which contour plots can be developed. The pressure distribution
data have been integrated (the procedure is given) to give force
and moment coefficient values and compatibility with coefficient
data from ESDU 82031 is ensured. Corrections made to the basic
experimental data are discussed.
