| titleOfInvention | A retrievable and reusable solid launch vehicle substage |
| abstract | The invention discloses a recoverable and reusable solid carrier rocket sub-stage, which comprises a sub-stage body, an inflatable thermal protection structure and a solid rocket motor; The front-end airbag in the shape of a rotating body on the surface, the front-end airbag includes a flexible heat insulation layer and a heat-resistant coating arranged sequentially from the inside to the outside; the solid rocket motor includes a combustion chamber shell with a chamber for placing the charge column, and the combustion chamber The inner wall of the casing is provided with a thermal protection structure for the combustion chamber. By adopting an inflatable thermal protection structure combining thermal protection + deceleration + cushioning, the front airbag can maintain a good aerodynamic shape, and the sub-stage will not be damaged by aerodynamic heating and large landing impact during reentry, which can achieve Recycling of sub-stages, recharging of rocket engines, replacement of one-time use parts, etc., can realize the reusability of sub-stages and their engines, thereby reducing the launch cost of solid launch vehicles. |
