“…The splicing component base also uses the same material. The high-temperature heating simulation was performed on the structure, and the initial splicing gap width is 10 mm [ 3 ]. The temperature nephogram, deformation nephogram, and stress nephogram of the transverse splicing component are shown in Figure 12 .…”

“…As a material applicated in extreme high temperature environments, it needs to have excellent properties, such as high temperature resistance, ablation resistance, and oxidation resistance, etc. In recent years, there has been more and more research on high temperature resistant materials, such as high temperature structural ceramics [ 1 , 2 , 3 ], high nitrogen steel [ 4 , 5 ], etc. In aerospace, aircraft, and other fields, steel, as an indispensable material, needs to withstand high temperatures in service.…”

As a steel with high strength, good plasticity and fracture toughness, high temperature resistance, and corrosion resistance, Cr18Mn18N is widely used in industrial engineering and military fields. However, in a high temperature environment, Cr18Mn18N needs to be subjected to higher temperature, resulting in excessive expansion deformation and larger stress, which will greatly damage the stability and service life of the material structure. In this paper, the high temperature arc wind tunnel is used to heat the high nitrogen steel material with prefabricated round structure, and the surface images of the material are collected at the temperature of 1500 K. After comparison, it is found that the material is well preserved in a high temperature environment, indicating that the circular structure has better thermal protection ability. Based on the experiment, the thermal-fluid-solid coupling model is established, and the surface temperature field, deformation field, and stress field are analyzed. Different surface structures are designed, and numerical models of horizontal and vertical splicing components are established. Through numerical simulation, the surface structure is optimized, the surface temperature of the material is reduced, and the gap change trend of the splicing component is displayed. This work has theoretical significance for the application of materials in a high temperature environment and the optimization and improvement of material surface structure.

“…The ablation property test is essential to accurately evaluate whether the ATPCs meet the thermal protection requirements of supersonic vehicles. Recently, several methods, such as quartz lamp, [19,20] oxy-acetylene flame, [21,22] plasma wind tunnel, [23,24] and arc-jet [25,26] have been widely used to ablate the materials. However, it should be mentioned that the high temperature caused by the aerodynamic heating effect during the hypersonic flight will partially or completely ionize the air and form a typical plasma environment on the surface of the ATPCs.…”

Novel hybrid ablation thermal protection coatings (FHMP‐ATPCs), employing iron trioxide (Fe2O3) powder, hollow glass microspheres, and mica powder as the fillers in hydroxyl‐terminated silicone oligomer‐bridged epoxy resins (PSG) copolymer, is investigated using an aerothermal‐vibration coupling test system. The ablation behavior and structural reliability of FHMP‐ATPCs with varying coating thickness were studied. During the test, the total enthalpy of airflow and dynamic pressures are 23 MJ/kg and 300 Pa, accompanied by the random vibration with a frequency of 20–2000 Hz and a total root‐mean‐square acceleration of 14.9g. The maximum surface and back‐face temperatures of the coating with the thickness of 2 mm reached 836.2°C and 156.4°C, respectively. Results also showed that the reduction of thickness obviously suppressed the surface temperature and increase in back‐face temperature yet maintaining high structural reliability. Compared with DGEBA‐based coatings, the PSG‐based coatings showed excellent structural reliability during the test. The study provides a solution for obtaining high performance ATPCs, which are highly desired for supersonic vehicles.
