| 摘要 | A dual-walled ceramic matrix composite (CMC) component comprises: a CMC core having a hollow shape enclosing at least one interior channel; and a CMC outer layer overlying and spaced apart from the CMC core by a ceramic slurry-cast architecture positioned therebetween. Each of the CMC core and the CMC outer layer comprises ceramic fibers in a ceramic matrix. The CMC core further includes a plurality of through-thickness inner cooling holes in fluid communication with the at least one interior channel. The ceramic slurry-cast architecture defines a cooling fluid path over an outer surface of the CMC core that connects the interior channel(s) to an external environment of the dual-walled CMC component. The CMC outer layer may also include a plurality of through-thickness outer cooling holes in fluid communication with the cooling fluid path, thereby extending the cooling fluid path through the CMC outer layer. | ||||||
