The invention provides a method for regulating and controlling the
ablation resistance of a high-temperature pneumatic environment
ablation-resistant material based on fractal geometry, and belongs to the technical field of thermodynamic functional materials, fractal geometry and high-temperature pneumatic protection. The regulation and control method comprises the steps that an initial
geometric configuration of an anti-
ablation material is constructed, the anti-ablation material is formed by periodic arrangement of three-dimensional unit
cell structures in a plane, and fractal dimensions of the unit
cell structures in the initial
geometric configuration are determined; layering the unit
cell structure according to the similarity between the structure heights, and obtaining the number of
layers of the unit
cell structure, the duty ratio of each layer and the thickness of each layer; constructing a thermal impedance
transfer equation, and determining the thermal impedance of the
surface layer by using the fractal dimension, the number of
layers, the duty ratio of each layer and the thickness of each layer of the unit
cell structure; determining the
surface layer heat flux density or ablation rate by using the
surface layer thermal impedance of the unit
cell structure; and optimizing the configuration of the unit cell structure and the layer structure until the
heat flux density or ablation rate of the surface layer of the anti-ablation material meets the requirement, and obtaining the optimized
geometric configuration of the anti-ablation material.
