Description

technical field [0001] The invention relates to a sweat cooling test system and a test method based on an oxyacetylene platform, belonging to the technical field of aerospace thermal protection. Background technique [0002] In the field of aerospace, the severe aerodynamic and thermal loads borne by supersonic vehicles may lead to changes in the surface shape of the vehicle, and even reduce the structural strength and stiffness of the vehicle, affecting the normal flight of the vehicle. Therefore, it is very important to set up a thermal protection system to eliminate the adverse effects of aerodynamic thermal loads, which is also one of the key technologies for the development of near-space vehicles. At present, the development of the ablation heat protection system has been relatively mature, but in terms of maintaining the stability of the aircraft's aerodynamic shape and improving the strike accuracy, the ablation heat protection system still has certain limitations, an...
