[citation needed] This fact, together with the simpler engine geometry with concomitant increase in component efficiencies, results in superior predicted performance at flight Mach numbers beyond 12.
[4] A critical challenge is to confine the detonation in a small area, without allowing it to direct energy upstream towards the fuel source or downstream where it loses force.
In 2021 an experimental device maintained a detonation in a fixed location for 3 seconds, far longer than earlier attempts.
Recent researches have stipulated that shcramjet, alongside its other airbreathing variants, can act as an efficient high-speed vehicle propulsion system for SSTO flights.
[6] These potential advantages have attracted substantial research on propulsive applications, as well as on the fundamental physical phenomena.
