Near-space hypersonic vehicles are subjected to complex environment including physics, chemistry and stress under high temperatue during high speed flight, which brings forth serious challenges and harsh demands for the thermal protective materials and structures of the aircrafts. On the basis of the requirement of ‘integration projects’ in GUIDANCE and the early research work of general programs and key projects, the integrated research is focused on experimental methods and techniques of thermal protective materials and structures such as C/C, C/SiC and thermal protective coatings under ultra high-temperature by means of interdisciplines and complentary advantages. The emphasis is to solve the critical issues, such as development of new sensor technologies, non-contact measurement methods and characterization techniques of critical parameters with temperature over 1500 ℃. The goal is to establish the experimental methods and platforms to characterize the key parameters of thermal protective materials and structures in mechanical/thermal/oxidizing coupled environment. The efforts will be devoted to clarifying the physical and chemical process and failure mechanism of materials and structures under complicated high-temperature environment and providing experimental data for the optimum design of thermal protective materials and structures. It is expected that a group of excellent talents and research teams for fundamental researches will be cultivated and a good foundation will be established for great-leap-forward developments of thermal protective materials and structures of near-space hypersonic vehicles.
