VFP uses a relaxation process to solve finite-difference<br \/>\nforms of the full nonlinear velocity-potential equation for the<br \/>\nflow around the three-dimensional geometry. The viscous effects are<br \/>\nmodelled using a coupled semi-inverse swept tapered integral<br \/>\nboundary-layer method. The VFP program was developed over a period<br \/>\nof years at ARA, Bedford and RAE\/DERA (now QinetiQ), Farnborough,<br \/>\nand is made available by ESDU under the terms of an agreement with<br \/>\nQinetiQ. Used originally on mainframe computers, VFP has provided<br \/>\nvaluable data in the design of a number of aircraft. With advances<br \/>\nin computers, it has become possible to perform runs of VFP on a PC<br \/>\nwithin a few minutes. One of the advantages of the VFP method is to<br \/>\nprovide a rapid process to produce valuable data to assess the<br \/>\naerodynamic qualities of wings as part of the design process.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Viscous Full-Potential (VFP) Method for Three-Dimensional Wings and Wing-Body Combinations &#8211; Part 3: Error Messages, Failures and Suggested Remedies<\/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>2014-06<\/td>\n<td>16<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":557513,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-557505","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\/557505","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\/557513"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=557505"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=557505"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=557505"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
