High speed, air-breathing engines are known as ramjets or scramjets because they ram oxygen into the front of the engines.
Scramjets, also known as supersonic combustion ramjets, can theoretically halve payload weights by carrying only fuel - such as liquid hydrogen - rather than both the fuel and oxygen carried by traditional rockets.
The company has a patented variation of the ramjet it calls an ejector ramjet that can operate at lower speeds than the ramjets of the 1960s.
