The analyses investigate the effect of 5-100 Hz vibration acceleration loads of the Falcon Heavy and Delta IV Heavy launch vehicles. The radiator module comprises of a Cs-Ti heat pipe with HOPG\/Ti heat spreading fins mounted into a titanium frame and the panel comprises of ten modules hydraulically coupled in parallel. The radiator panel has an areal density of 2.98 kg\/m2 and rejects &gt;56 kWth into space at a surface average temperature of 600 K. The highest induced Von Mises stresses for the radiator module during launch of 11.9 -12.9 MPa are only 1.2%-1.5% of the yield strength of the Ti alloy walls and the highest induced tensile stresses are &lt;6% of the bending failure of HOPG. The highest induced Von Mises stresses in the radiator panel during launch on the Falcon Heavy in the Ti alloy walls of 22.5-97.6 MPa are &lt;10% of the titanium alloys yield strength of 898 MPa. These results confirm that the designed lightweight Cs-Ti heat pipe radiator panel would survive vibration acceleration loads during launch..<\/p>\n<p class=\"p2\"><b>Keywords: <\/b>Heat Pipes, Fission Surface Power, Radiators, Finite Element Analysis, Launch Stresses<\/p>\n","protected":false},"featured_media":53294,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,3901],"product_tag":[],"class_list":["post-53673","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2025-papers","first","instock","downloadable","virtual","purchasable","product-type-simple","czr-hentry"],"jetpack_sharing_enabled":true,"brands":[],"_links":{"self":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product\/53673","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media\/53294"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=53673"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=53673"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=53673"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=53673"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=53673"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
