Supersonic combustion is used to propel hypersonic scramjets, which travel at speeds over Mach 5. These engines are fundamentally different from traditional jet engines. They feature a more ...

But while pretty much any other technology you could imagine has progressed by leaps and bounds in the nearly 30 years that have passed, the state-of-the-art in hypersonic scramjets hasn’t moved ...

The key to hypersonic vehicles is Scramjets, which are air breathing engines capable of sustaining combustion at supersonic speeds without using any moving parts. The ground test of the scramjet ...
