As a result, scramjets have become something of a well-studied technology in search of a practical application.<\/p>\n<p>To reach these hypersonic speeds, Michael Smart, professor of hypersonics at the University of Queensland in Brisbane plans to combine an uncrewed scramjet with conventional rockets. He believes his Spartan launch system could radically reduce the costs of blasting satellites into orbit.<\/p>\n<p>\u201cAll conventional satellite launch systems use different stages,\u201d says Smart. \u201cThere\u2019ll be a first stage rocket that normally gets up to Mach 5 or 6, you\u2019ll have a second scramjet stage that goes two thirds of the way to space and you\u2019ll have a final upper stage that takes the satellite into orbit.\u201d<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.nextbigfuture.com\/2016\/11\/australia-developing-low-cost.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:+blogspot\/advancednano+(nextbigfuture\">http:\/\/www.nextbigfuture.com\/2016\/11\/australia-developing-lo...tbigfuture<\/a>)  --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Once you get to mach 5+ hypersonic speed, then a scramjet works and it is by far the most efficient type of engine for hypersonic speeds.
