| Abstract: | The ablation and denudation of carbon/carbon composites appear under the condition of strong shock wave and the circumgyration of carbon grain denuded is brought about by many kinds of factors, such as geometry shape and velocity grades. The effect on circumgyration of carbon grain and the ablation of nose-tip during re-entry of stratagem missile is analyzed according to thermal transfer theory, thermo-aerodynamics and N-S equation. The result presents that the circumgyration of carbon grain is benefit to thermal protection. |
