Imagine a hypothetical scramjet engine with a combustion chamber that’s one meter long; at a velocity of Mach 5, air traveling in a straight line will only be inside the chamber for a fraction ...

The scramjet — or "supersonic combustion ramjet" — engine is an innovation on the original ramjet engine design that changes the internal combustion chamber to remove the shock cones.

In this connected pipe test mode, in which the combustion chamber is connected directly to the air heater ... the improvement and better understanding of future ramjet and scramjet engines, but also ...

(CNN) -- The National Aeronautics and Space Administration conducted a third and final test flight of the unmanned X-43A aircraft, which uses an experimental scramjet engine designed to push the ...

An array of propellants are evaluated in combustion chamber and engine tests under ambient and ... green propellants and scramjet engines. Advanced propellants are vital for replacing highly toxic ...

The results, published in China’s Journal of Experiments in Fluid Mechanics, suggest combustion rates 1,000 times faster than traditional scramjet engines, with operational capability between Ma ...
