Claim:
1. A ceramic matrix composite airfoil comprising: a longitudinal shaped laminate core comprising a core wrap formed of a plurality of ceramic composite plies, a cooling fluid flow network formed of one or more ceramic foam components at least partially positioned around the longitudinal shaped laminate core; an airfoil skin formed of a ceramic fiber lamina disposed about the longitudinal shaped laminate core and the cooling fluid flow network; a rotatable blade formed from the ceramic composite airfoil; a blade platform connected to the rotatable blade; and at least one ceramic foam component positioned within the blade platform, wherein the at least one ceramic foam component positioned in the blade platform is fluidly connected to the one or more ceramic foam components positioned around the longitudinal shaped laminate core, and wherein the at least one ceramic foam component positioned in the blade platform is generally orthogonal to the one or more ceramic foam components positioned around the longitudinal shaped laminate core.
