Total pressure loss data are given for three classes of intake, namely, pod or pitot types with well rounded lips, intakes with well rounded lips and long and\/or curved ducts leading to the engine, and sharp-lipped intakes. It is assumed that the flow is unchoked at take-off. The Mach number range of the data is 0 to 0.5. Values of thrust loss per unit intake total pressure loss are given for engines having two types of engine control and unreheated specific thrusts in the range 25 s to 90 s (corresponding to bypass ratios up to about 10). Data are applicable to unreheated or reheated turbo-jet or turbo-fan engines.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Effect of Intake Total Pressure Loss on Net Thrust at Take-Off: Turbo-Jet and Turbo-Fan Engines<\/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>1977-03<\/td>\n<td>7<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":558082,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-558073","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\/558073","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\/558082"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=558073"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=558073"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=558073"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
