A scramjet is a supersonic ramjet and aside from differences with dealing with internal supersonic airflow works like a conventional ramjet. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Except for scramjet engines, all airbreathing jet engines need ...
As spectacular as space shuttle flights still are, they are also about the past. Scramjet propulsion is about the future. Unlike rocket engines, scramjets (supersonic combustion ramjets) are air-breathing engines that inhale oxygen from the atmosphere to achieve near rocket engine velocities and a...
They found that the flame-forward and flashback are mainly caused by the interaction between the flame region of the cavity downstream and the boundary layer. Jiang et al. [13], who demonstrated the possibility of a standing oblique detonation (SOD) ramjet, illustrated the surging of a ...
Despite these advantages, the development and application of scramjet engines are considered to be more challenging than those of rockets. Challenges include the Mach number limitation of the ramjet effect, the flow deflection occurring in the combustion chamber under complex shockwave interactions, the ...
The scramjet mode corresponded to cavity shear-layer-stabilized combustion, and the flame of the ramjet mode was combined with cavity shear-layer- and recirculation-stabilized combustion. In addition, many researchers have focused on subsonic and supersonic combustion modes in dual-mode scramjet ...
However, compared with the liquid fuel scramjets, solid fuel scramjets have the same advantages as traditional solid fuel engines, such as simple structure, high energy density, good maneuverability, and long storage time, etc. Therefore, the solid fuel scramjet has gradually developed in the ...
