ESDU 95022 presents graphical data for centre of pressure position of delta and rectangular wings of aspect ratio 0.25 to 4 for angles of attack up to 90 degrees. They were obtained by correlating results from the literature. However, for cropped-delta wings there were fewer data and it only proved possible to present graphs applying to pre-stall conditions for angles of attack up to 30 degrees, aspect ratio from 0.1 to 4 and taper ratios from 0.1 to 0.5, although a method of extrapolation to taper ratios from 0.5 to unity is suggested. The correlation in that case also involved the aerodynamic centre position, a graph for which is reproduced from ESDU 70011. The methods apply at low subsonic speeds; a method of extrapolating to high Mach numbers is given but is tentative for the rectangular and cropped-delta wings although for delta wings it is found to work well at Mach numbers up to 0.95. The method applies to thin, sharp-edged wings without camber or twist. It is accurate to 2 per cent of root chord length. The pitching moment is obtained using the normal-force data from ESDU 93034.
