Unstart Coupling Mechanism Analysis of Multiple-Modules Hypersonic Inlet [PDF]

open access: yesThe Scientific World Journal, 2013
The combination of multiplemodules in parallel manner is an important way to achieve the much higher thrust of scramjet engine. For the multiple-modules scramjet engine, when inlet unstarted oscillatory flow appears in a single-module engine due to high ...

Carbon Fiber Oxidation in 4D. [PDF]

open access: yesAdv Mater
The oxidation of porous carbon fiber heat shield material at high temperatures is imaged using time‐resolved synchrotron X‐ray microtomography. Resolving the interplay between species diffusion and carbon‐oxygen reaction rate reveals spatially and temporally varying degradation across oxidation regimes, with profound implications for in‐depth material ...

Fluid/Thermal/Structural Coupling Simulation on Effects of Forebody-Inlet Thermal Deformation on Intake Performance

open access: yes气体物理, 2023
Intake performance is one of the most important factors relating with the forebody-inlet design for air-breathing hypersonic vehicles. The intake performance will be altered due to hypersonic flow field change by the thermal deformation of forebody and ...

Self-Start Characteristics of Hypersonic Inlet When Multiple Unstart Modes Exist

open access: yesApplied Sciences, 2023
Intense shock boundary-layer interaction may lead to multiple unstart modes existing in a hypersonic inlet. Thus, self-start problems become complex and cannot be explained using the classical double-solution theory of air inlet.

Numerical Research on the NS-SDBD Control of a Hypersonic Inlet in Off-Design Mode

open access: yesAerospace, 2022
The overall performance of a scramjet inlet will decline while entering off-design mode. Active flow control using nanosecond surface dielectric barrier discharge (NS-SDBD) can be a novel solution to such inlet–unstart problems.
