hypersonic going over the top

This is extraordinary news.  It means that we can expect been able to reach ramjet engine speeds from take off.  swi8itching over to a ramjet then becomes possible if one is high enough and a ramjet makes a vrun up to orbit possible..  that has always been the gap and we can jump it.

Still a long ways off but no longer just impossible.  Exciting times.

we now have a bif thimper able to directly boost a hundred tonsintoo orbit and this promises to allow a commute.

We all gave up too soon.

Physics Broken: Rolls Royce's New Ice Cool Engine Achieves Mach 7 Without Melting At Mach 7, the sky turns into fire. In this deep dive, we explore how Rolls-Royce and Reaction Engines are challenging one of aerospace engineering’s most unforgiving barriers: surviving hypersonic heat. When aircraft push beyond Mach 5, the air itself becomes a 1,000°C plasma blast furnace capable of melting advanced alloys in seconds. Traditional jet engines fail. Even legends like the SR-71 Blackbird and the F-22 Raptor never came close to these extremes. For decades, reusable hypersonic flight seemed impossible. But the SABRE engine (Synergetic Air-Breathing Rocket Engine) may change everything. At the heart of this breakthrough is a revolutionary *precooler* system capable of chilling 1,000°C airflow to manageable temperatures in under 1/20th of a second. Combined with ceramic matrix composites, fuel-based regenerative cooling, and advanced frost-control systems, this technology doesn’t fight the heat — it manages it. From ground tests in Colorado using a modified General Electric J79 as a hypersonic blowtorch, to integrated UK test runs simulating speeds beyond the Concorde, this is the story of how engineers are rewriting the rules of flight. Could this mean: • London to Sydney in under 4 hours? • Fully reusable spaceplanes? • Mach 5+ reconnaissance aircraft? • A new era of sixth-generation air dominance? The wall of fire that stopped hypersonic aviation for 60 years may finally be cracking.
