Comparison of Scramjet and Shcramjet Propulsion for an Hypersonic Waverider Configuration
44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2008Ramjet propulsion is often proposed for airbreathing applications with speeds higher than Mach 3. However, for speeds higher than Mach 5, the performance of a ramjet drops significantly and the scramjet is the preferred option. The shockinduced combustion ramjet, or shcramjet, is also an interesting alternative at higher flight speeds.

Radiative heating in scramjet combustors
31st Thermophysics Conference, 1996Currently, there is considerable interest in scramjet engines for hypersonic aircraft and missiles. This paper presents preliminary calculations of the radiative heating of the walls of scramjet combustion chambers. The analysis assumes isothermal, constant property ow elds that are representative of actual combustor ow elds.

RANS investigation of the effect of pulsed fuel injection on scramjet HyShot II engine
Aerospace Science and Technology, 2019Effective and efficient fuel–air mixing plays a critical role in the successful operation of scramjet engines. To enhance the fuel–air mixing in supersonic combustion systems with a short flow residence time, the pulsed fuel injection strategy in a ...

Flowfield Reconstruction and Shock Train Leading Edge Detection in Scramjet Isolators
, 2020Within a scramjet, the location of the shock train will change as the backpressure changes. When the shock train leading edge moves out from the entrance of the isolator, the engine usually goes in...

Wave processes in scramjet thrust generation
Combustion and Flame, 1988The investigation explores the steady, supersonic expansion and compression wave processes involved in generating thrust from a combustion jet in a two-dimensional scramjet. Two types of thrust generating wave are produced by the jet. The first is the injection compression waves associated with injection and combustion of the fuel, and the second is ...

Numerical study of a scramjet engine flow field
19th Aerospace Sciences Meeting, 1981A computer program has been developed to analyze the turbulent reacting flow field in a two-dimensional scramjet engine configuration. The program numerically solves the full two-dimensional Navier-Stokes and species equations in the engine inlet and combustor, allowing consideration of flow separation and possible inlet-combustor interactions.
