Hempsell. (2021),\u00a0<em>JBIS<\/em>, 74, pp.234-236<\/h3>\n<p><strong>Refcode:\u00a0<\/strong>2021.74.234<\/p>\n<p><strong>Abstract:<\/strong><\/p>\n<p>Globus has produced an argument for the optimum overall shape for a large spinning space habitat, considering minimising overall wall area, maximising floor area, while maintaining an inertia ratio compatible with stable spin. The resulting shape was a cylinder with a height 1.3 times the floor radius. This shape was used in Globus\u2019 own Kalpana habitat designs and also the British Interplanetary Society\u2019s Avalon study. Globus assumed a complete cylinder with a full disc end wall. Here we look at the impact of using a roof to create a hollow cylinder, reducing the pressurised volume for a given usable floor area. It was found that the structural mass differences are small and in a real situation other secondary factors would have a larger influence. Therefore, the selection between them would be based on the saving in the mass of the atmosphere and the aesthetic of the overhead sky.<\/p>\n","protected":false},"featured_media":10270,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,171],"product_tag":[3236,3235],"class_list":["post-10269","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2021papers","product_tag-globus-cylinder","product_tag-space-settlements","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\/10269","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\/10270"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=10269"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=10269"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=10269"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=10269"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=10269"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
