The invention relates to an arc ablation simulation test piece. The test piece comprises a force bearing structure; the heat protection assembly is fixed to one side of the force bearing structure, a through groove is formed in the heat protection assembly, and the through groove penetrates through the two opposite sides of the heat protection assembly in the extending direction of the heat protection assembly; the pressing plate is fixed to the through groove, and one side of the pressing plate is attached to the force bearing structure. By arranging the force bearing structure, the heat protection assembly, the through groove formed in the heat protection assembly and the pressing plate fixed in the through groove, a gap at the butt joint position of cabin sections of a whole-course hypersonic aircraft can be jointly simulated, the test piece is used in an assessment test of a dynamic thermal arc wind tunnel, the assessment cost can be effectively reduced, and the test efficiency is improved. The problem that the assessment cost is high even if the reliability of the local thermal protection structure system of the thermal protection system of the aircraft is verified by adopting the local structure of the whole-course hypersonic aircraft in the related technology is solved.
本申请涉及一种电弧烧蚀模拟试验件,其包括:承力结构;防热组件,所述防热组件固定于所述承力结构的一侧,所述防热组件开设有通槽,所述通槽沿所述防热组件的延伸方向贯穿所述防热组件的相对两侧;压板,所述压板固定于所述通槽,且所述压板的一侧贴合于所述承力结构。通过设置承力结构与防热组件,以及在防热组件中开设的通槽,并在通槽中固定压板,可以共同模拟全程高超飞行器的舱段对接处的缝隙,将试验件用于动态热电弧风洞的考核试验中,可以有效降低考核成本,解决了相关技术中即使采用全程高超飞行器的局部结构验证飞行器热防护系统局部热防护结构系统的可靠性,其考核成本也较大的问题。
