Article
Material strength under complex stress states is vital for structure design. This paper studied the strength and failure behaviour of 3D C/C composites under compression-shear coupled loads. Experiments were conducted using a modified anti-symmetric four-point bending (MAFPB) method and off-axis compression method. Two dominant failure modes were o...
Article
A coupling framework of hypersonic flow, heat transfer and structural response is presented in this paper in order to accurately predict aerodynamic environment, extreme aerothermal environment, as well as thermal and structural response for hypersonic flight. Multi-field coupling analysis is implemented in conjunction with the hypersonic chemical...
Article
Extreme high-temperature flight environment exposure of ultra-high temperature ceramic materials will result in their oxidations, and the generated oxide products on the surface which have different thermal-physical properties, thus will affect the heat transfer process. For pre-oxidized ZrB2 and ZrB2-SiC materials, the thickness of oxidation layer...
Article
In order to investigate the ablation mechanisms of carbon/phenolic composites which were used in thermal protection system of hypersonic vehicles with blunt shapes, the mathematical model for ablation behavior was established firstly, the model took a variety of energy dissipation mechanisms, including the thermal radiation of material surface, the...
Article
Thermal protection material and structure is one of the key technologies enabling near space hypersonic flights. For the past few years, new design and analysis methods have constantly emerged. This paper will focus on these new concepts and technologies, and a survey of literature reveals that: design of thermal protection materials has been devel...
Article
Composites are multi-scale in nature. The multi-scale simulation stands among one of the most important methods for response analysis of composites, due to its ability to incorporate micro scale damage initiation, evolution and the corresponding effects in macro material property and mechanical behavior. The multi-scale asymptotic expansion theory...
Article
The aero thermal heating rate of hypersonic vehicle surfaces is a key input parameter for thermal protection system design, It is of great significance, in view of the limitation of computation and ground test, to obtain the aerothermal heating rate in the real environment of flight, and then validate and upgrade the computation code and ground tes...
Article
With the development of hypersonic vehicles, aerodynamic heat loads on thermal protection materials under high enthalpy disassociated environment is affected by surface catalytic properties to a large extent. According to the research development in characterization of high enthalpy environment and surface catalytic properties, this paper presents...
Article
Aerospace structural thermal control design for heat sink leaved the most demanding for mass, volume and environmental adaptability. PCM (Phase Change Materials) was in an order of magnitude higher efficiency, compared to the traditional quality heat sink. PCM slug fabricated by vacuum infiltration, in which Sn-Bi alloy was used as phase change mat...
Article
The oxidation behavior of ZrB2-20% vol SiC ceramic composites, which is typically used as the potential composite materials of nose, in the ambience pressure of 40Pa and temperatures between 1400 and 1700°C of the atomic and molecular oxygen environment were studied. The practical situation of tip materials exposed in the plasma of high temperature...
Article
The demanding requirements of high-speed aircraft for structural efficiency lead to their thermal protection system to be lightweight and integrated. The new thermal-mechanical coupling integrated thermal protection system (ITPS) has great potential for development. Firstly, the concept and characteristics of a new integrated thermal protection str...
