Direct-Connect Test of Solid Scramjet with Symmetrical Structure
The solid scramjet has become one of the most promising engine types. In this paper, we report the first direct-connect test of a solid scramjet with symmetrical structure, carried out using boron-based fuel-rich solid propellant as fuel. During the test,

Experimental Study of the Formation and Evolution of Gas Jets in Supersonic Combustion Chambers
A simple and efficient flow field visualization method (based on shadow imaging) was applied in a direct-connect test to explore the influence of the momentum flux ratio and the jet angle on the formation and evolution of nitrogen jets in supersonic ...

Sizing of scramjet vehicles [PDF]
The current European project LAPCAT II has the ambitious goal to de¦ne a conceptual vehicle capable of achieving the antipodal range Brussels Sydney (∼ 18,000 km) in about 2 h at Mach number Ma = 8. At this high speed, the requirement of high lift to drag (L/D) ratio is critical to high performance, because of high skin friction and wave drag: in fact,
