The method takes the body-alone contribution (ESDU 89008 provides values for forebody-cylinders) and adds contributions from the wing (in the presence of the body) and from the change in body lift-curve slope due to the wing. Both contributions are obtained by factoring the isolated wing lift-curve slope from ESDU 70011 or 70012 (for subsonic or supersonic flow respectively). Equations and graphs are given for the factors. The wing factor is a function of span-to-body-diameter ratio, while, at supersonic speeds, the body correction factor depends on whether the Mach line from the wing tip intersects the root chord or passes downstream of its trailing-edge. In the latter case the factor is a function of body length downstream of the wing. The method applies to straight or swept-forward trailing-edges, but has been found to be satisfactory for moderate trailing-edge sweeps. It is found to compare with experiment within about 10 per cent. A worked example illustrates the use of the method.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Lift-curve slope of wing-body combinations<\/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>1995-12-01<\/td>\n<td>25<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":559029,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-559019","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\/559019","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\/559029"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=559019"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=559019"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=559019"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
