H. Cocks; C. M. Harman; P. A. Klenk; W. N. Simmons (2005),\u00a0<i>JBIS<\/i>,\u00a0<b>58<\/b>, 2-8<\/h3>\n<p><b>Refcode<\/b>: 2005.58.2<\/p>\n<p><b>Abstract:<\/b><br \/>\nActing as a virtual first stage, a hypervelocity launch together with the use of frozen hydrogen\/frozen oxygen propellant, offers a Single-Stage-To-Orbit (SSTO) system that promises an enormous increase in SSTO mass-ratio. Ram acceleration provides hypervelocity (2 km\/sec) to the orbital vehicle with a gas gun supplying the initial velocity required for ram operation. The vehicle itself acts as the centre body of a ramjet inside a launch tube, filled with gaseous fuel and oxidizer, acting as an engine cowling. The high acceleration needed to achieve hypervelocity precludes a crew, and it would require greatly increased liquid fuel tank structural mass if a liquid propellant is used for post-launch vehicle propulsion. Solid propellants do not require as much fuel- chamber strengthening to withstand a hypervelocity launch as do liquid propellants, but traditional solid fuels have lower exhaust velocities than liquid hydrogen\/liquid oxygen. The shock-stability of frozen hydrogen\/frozen oxygen propellant has been experimentally demonstrated. A hypervelocity launch system using frozen hydrogen\/frozen oxygen propellant would be a revolutionary new development in spaceflight.<\/p>\n","protected":false},"featured_media":7893,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[56,59,155],"product_tag":[1004,1002,1003,789,966,786],"class_list":["post-7892","product","type-product","status-publish","has-post-thumbnail","product_cat-journal-of-the-bis","product_cat-papers","product_cat-2005papers","product_tag-frozen-propellant","product_tag-hypervelocity","product_tag-ram-acceleration","product_tag-space-launcher","product_tag-spaceflight","product_tag-ssto","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\/7892","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\/7893"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=7892"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=7892"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=7892"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=7892"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=7892"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
