Description

technical field [0001] The invention relates to a mechanical-thermal composite environmental test device, which belongs to the technical field of aircraft structural strength and environmental assessment, and is used for simulating the thermal-noise composite environment faced by an aircraft during cruise or reentry on the ground. Background technique [0002] High Mach number aircraft, reusable vehicles, etc. are subjected to severe aerodynamic heat, noise and other complex environments during cruise and reentry, such as high-intensity noise generated by the propulsion system / boundary layer, which exceeds 170dB in local areas, due to Cruising in the atmosphere for a long time, the temperature of the large-area thermal protection system exceeds 1000°C, and the local temperature can reach above 2000°C. Under the action of high-intensity noise for a long time, fatigue damage will occur to the structure of the aircraft. The aerodynamic thermal environment changes the thermophy...
