摘要

Mechanical testing techniques in ultrahigh temperature environments are the crucial techniques related to the success or failure of heat-proof material design and structure safety design for hypersonic flight vehicles. This paper describes a self-developed radiation-based aerodynamic heating simulation system that can generate infrared radiation in ultrahigh temperature environments with the highest temperature up to 1500°C. This system is capable of simulating the transient nonlinear experiment environments accurately, with a rapid heating rate up to 210°C/s and with a heat flux up to 1.5Mw/m~2. Furthermore, this paper presents the full-field high-temperature deformation measurement under the 1550°C environment by using the digital image correlation method and also presents the abruption property test of a high-temperature composite material SiC/SiC specimen in a thermal strength environment up to 1400-1500°C. This aerodynamic heating simulation system and the mechanical testing methods in this paper have great value in military engineering applications for the design of hypersonic flight vehicles in the aerospace field.
