| Abstract: | Thermal protection is one of the main research subjects of hot launch technology.It is proposed to develop subscale test for combustion-gas jet based on the research of simulation on combustion airflow dynamics and similarity theory.By subscale test for combustion-gas jet validating the theoretical simulation results and thermal protection schemes,the ablation range and degree of launch structures are examined to guide the working way of thermal protection,therefore,the design approaches of scattering,plugging, avoiding,preventing and rapidly replacing are determined. |
