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.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Pitching moment of low-aspect-ratio cropped-delta wings up to high angles of attack at subsonic speeds<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/esdu\/\"><b>ESDU<\/b><\/a><\/td>\n<td>1995-09-01<\/td>\n<td>21<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":559339,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-559331","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-esdu","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/559331","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/559339"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=559331"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=559331"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=559331"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
