The invention discloses a thermal protection structure, the thermal protection structure comprises a thermal protection layer arranged on the outer wall of a main body layer and a connecting assembly used for connecting the main body layer and the thermal protection layer, the connecting assembly comprises a strain isolation piece, the strain isolation piece has elasticity, and at least part of the strain isolation piece is attached to the inner wall of the main body layer; one end of the connecting piece is mounted on the thermal protection layer, and the other end of the connecting piece sequentially penetrates through the thermal protection layer and the main body layer and is detachably connected with the strain isolation piece. According to the thermal protection structure disclosed by the invention, the main body layer and the thermal protection layer are detachably connected by adopting the variable isolation piece and the connecting piece, so that high-density heat flow at the connecting piece only causes the strain isolation piece to generate relatively high thermal stress, and the thermal stress generated on the main body layer is relatively small, so that the damage of the thermal stress to the main body layer is reduced; the service life of the main body layer is prolonged.
本发明公开了一种热防护结构,该热防护结构包括设置在主体层外壁上的热防护层、以及用于连接主体层和热防护层的连接组件,连接组件包括:应变隔离件,具有弹性,应变隔离件至少部分贴合设置在主体层的内壁上;连接件,连接件的一端安装在热防护层上,另一端依次穿过热防护层和主体层,并与应变隔离件可拆卸地连接。本发明中的热防护结构,其采用变隔离件和连接件将主体层和热防护层进行可拆卸地连接,使得连接件处的高密度热流仅导致应变隔离件产生较高热应力,而在主体层上产生的热应力较小,从而降低热应力对主体层的损伤,延长主体层的使用寿命。
