The model consists of multiple, 1 kg payloads mounted at the tip of 1,000-meter (1 km) rotating arms constructed from commercially available Kevlar. At 75.5 RPM, the tip velocity reaches 7.91 km\/s, more than sufficient for Earth escape velocity at LEO. We analyze stress distribution, axial load, and material constraints, confirming that Kevlar remains within tensile limits under optimized conditions for escape velocities once in LEO. The design offers a scalable, reusable companion to chemical propulsion, with implications for orbital logistics and interplanetary missions. The analysis shows that high-performance deployment systems can be constructed using conventional, low-cost, available materials and technologies, opening new pathways for high-efficiency space payload deployment and scientific research..<\/p>\n<p class=\"p2\"><b>Keywords: <\/b>Momentum Exchange Tethers, Kevlar, Rotating Space Structures, Non-Chemical Propulsion, Tensile Stress Analysis<\/p>\n","protected":false},"featured_media":56894,"template":"","meta":[],"pwb-brand":[],"product_brand":[],"product_cat":[3911],"product_tag":[],"class_list":["post-56947","product","type-product","status-publish","has-post-thumbnail","product_cat-2026-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\/56947","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\/56894"}],"wp:attachment":[{"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/media?parent=56947"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/pwb-brand?post=56947"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_brand?post=56947"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_cat?post=56947"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bis-space.com\/shop\/wp-json\/wp\/v2\/product_tag?post=56947"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
