Description

technical field

[0001] The invention relates to the technical field of aircraft testing, in particular to an extreme high temperature thermal strength experimental system for a complex curved surface structure used for aerospace aircraft testing. Background technique

[0002] When the aerospace plane flies at hypersonic speed in the atmosphere, its structural surface is subjected to severe aerodynamic heating. The aerodynamic heating temperature peak is high, the temperature change rate is large, and the thermal field is extremely complex, which makes the structural thermal strength test in the aerospace plane strength test. It is extremely challenging to evaluate and evaluate the complex surface temperature and heat flow field distribution with local temperature exceeding 1800°C and temperature variation exceeding 200°C / s, it is difficult for the existing traditional experimental techniques to meet the experimental simulation requirements at the same time.
