Research on the Thermal Protection Method for Rapid Repair of Launch Pad
Thermal protection is a regional protection measure covering the outer surface of the launch pad to prevent the bearing structure of the launch pad from being eroded by the rocket launch gas flow. It is a key link to ensure that the launch pad can reliably carry the rocket safely. In recent years,as the launch frequency of the conventional liquid carrier rocket represented by the Long March 2C rocket has increased year by year,the recovery time of the launch pad after the launch of the rocket has also been greatly reduced. Therefore,a rapid recovery scheme for thermal protection of the launch pad is proposed,which combines the ablation type heat protection technology with the absorption type heat protection technology,and the modular thermal protection components are designed to realize rapid replacement through simulation,test and use. The results show that the repair time of the new thermal protection is shortened from 3 days to 1 day,and the protection effect is good,which can meet the needs of high-density rocket launch.
