Simulation of a hydrocarbon fueled scramjet exhaust [PDF]

Exhaust nozzle flow fields for a fully integrated, hydrocarbon burning scramjet were calculated for flight conditions of M (undisturbed free stream) = 4 at 6.1 km altitude and M (undisturbed free stream) = 6 at 30.5 km altitude.

Radiant heating tests of several liquid metal heat-pipe sandwich panels [PDF]

Integral heat pipe sandwich panels, which synergistically combine the thermal efficiency of heat pipes and the structural efficiency of honeycomb sandwich construction, were conceived as a means of alleviating thermal stress problems in the Langley ...

CYCLE ANALYSIS OF SCRAMJET ENGINES

CYCLE ANALYSIS OF SCRAMJET ENGINES
In this paper, engine cycles for airframe-integrated scramjets employing hydrogen fuel are analyzed to investigate regenerative engine cooling characteristics, required pump exit pressure, and overall engine thrust. An expander cycle and a gas generator(G.G.) cycle are examined. It is found that the engine can function with either of these cycles.

Viscous computations of cold air/air flow around scramjet nozzle afterbody [PDF]

The flow field in and around the nozzle afterbody section of a hypersonic vehicle was computationally simulated. The compressible, Reynolds averaged, Navier Stokes equations were solved by an implicit, finite volume, characteristic based method.

Combustion of hydrogen in a two-dimensional duct with step fuel injectors [PDF]

An investigation of the combustion of hydrogen perpendicularly injected from step fuel injectors into a Mach 2.72, 2100 K vitiated test gas was conducted. The model simulated the flow between the center and side struts of an integrated scramjet module at

Analysis of Scramjet Engine Characteristics

Analysis of Scramjet Engine Characteristics
In a previous report, we compared scramjet engine characteristics of different propellant feed cycles, and discussed engine performances. In this study, we examined a hydrogen fueled airframe-integrated scramjet, considered the cooling of the airframe as well as the engine, and analyzed how engine characteristics depend on such parameters as flight ...
