Also, an expression for<br \/>\nthe longitudinal position of any fraction of the aerodynamic mean<br \/>\nchord is determined.<\/p>\n<p>Investigations then establish, for a straight-tapered<br \/>\ntrapezoidal wing, the relationships between the aerodynamic mean<br \/>\nchord and the chord at the centroid location, with respect to their<br \/>\nlengths and longitudinal locations.<\/p>\n<p>Finally, equations are provided to determine the geometric<br \/>\nproperties of a multi-panel wing by consideration of the geometry<br \/>\nof the individual panels. The calculation procedures are also<br \/>\ntabulated as assistance to the user in the computation of<br \/>\nmulti-panel wing planform geometry and a worked example illustrates<br \/>\nthe use of these tables.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Derivation of equations for the geometrical properties of straight-tapered and multi-panel wings<\/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>2012-05-01<\/td>\n<td>29<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":559887,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-559877","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\/559877","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\/559887"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=559877"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=559877"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=559877"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
