The oxidizer-to-fuel (O\/F) ratio for peak Isp is approximately 7:1 by mass. While lower than liquid oxygen systems (Isp ~310\u2013340s), the operational simplicity often justifies the performance trade-off.<\/p>\n<div class=\"chem-data-box\">\n<div class=\"label\">Specific Impulse (N\u2082O\/HTPB)<\/div>\n<div class=\"value\">Isp \u2248 250 \u2013 270 s<\/div>\n<\/div>\n<h2>Notable Applications<\/h2>\n<p>SpaceShipOne and SpaceShipTwo (Virgin Galactic) use N\u2082O\/HTPB hybrid motors designed by Sierra Nevada Corporation.
