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 efficient, ...

This engine does not need to slow the incoming air for combustion, instead maintaining supersonic airflow and achieving higher fuel efficiency. Scramjets were conceptualized as far back as 1958 but ...

The United States is actively pursuing the development of hypersonic weapons in view of rising threats from Russia and China. A new report on the topic suggests that the U.S. hypersonic weapons will ...

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 ...
